- (4) Command Line Switches
- =========================
-
- DISPLAY understands several command-line parameters. Some of them are
- useful for setting up your preferred configuration or overwriting
- config.dis options. Others are for command-line processing.
-
- Symbol :
- aaa | bbb : You can use aaa or bbb. They are equivalent.
- [ aaa ] : aaa is optional.
- < aaa > : Use other value or string to replace aaa.
-
- (a) For normal use :
- display [-d|--display <initial_display_type>] [-s|--sort <sort_method>]
- [-f <config_file>] [-c <config_file] [-a] [-n l|g] [--help|-?]

- -n: Do not read Local or Global config file.
- Global: where DISPLAY.EXE resides. Local: where you start DISPLAY.
- -t: change to the specified directory when DISPLAY starts up.
- filename_mask: separated by ';'. quotation marks are needed before and after
- + filename_mask. Mask length should be less than 128.
- report_file: Contains useful information generated by DISPLAY.
- Please don't use relative path(e.g.: ../qqq/report).
-
- (b) For command-line single image/movie viewing :
- display [--width|-w <image_width>] [--height|-h <image_height>]
- + [--noask|-k] [--stay] [--type <standard extension>]

-
- Upper-Left corner : Never sleep.
- Low-Right corner : Sleep now.
-
-
- (8) Preview
- ===========
- Preview lets you see the small image of this picture before loading it.
- You can use key 'p' to turn on/off preview (DISPLAY will switch to
- graphic text mode if necessary). Currently DISPLAY support 2 strategies
- for preview, i.e. loading preview from .TNL file and original image.
- The first method is faster, but you need to make .TNL file first. You can
- also use PKZIP or ZIP to archive .TNL images together to reduce the disk
- space occupation. This .ZIP file is called 'packfile'.
- The procedures of loading preview are described below:
- (use_tnl_preview, global_tnl_path, global_tnl_packfile & local_tnl_packfile
- are resources in config.dis)
-
- 1.
- If 'use_tnl_preview' is false(i.e. 0), goto step 3.
- Load preview from .TNL file within current directory. Filename is the
- same as current image filename, except that extension is changed to .TNL.
- If success, return.
- If 'local_tnl_packfile' is specified, try to load the corresponding .TNL
- image from this file within current directory.
- If success, return.
- 2.
- If 'global_tnl_path' is not specified, goto step 3.
- Load preview from .TNL file within 'global_tnl_path'. Filename is the
- same as current image filename, except that extension is changed to .TNL.
- If success, return.
- If 'global_tnl_packfile' is specified, try to load the corresponding .TNL
- image from this file within 'global_tnl_path'.
- If success, return.
- 3.
- Don't use .TNL file. Load preview from current image.
- Return.
-
-
- (9) Initialization steps
- ========================
-
- The followings are what happen when you start DISPLAY. There's nothing
- you have to do, but it helps to avoid errors. The important thing is,
- that a command-line option overrides the configuration file option.
-
- 1. Find allowed screen resolutions (for .grn video drivers only).
- 2. Read the configuration files (Global first, then Local).
- Global: where DISPLAY.EXE resides. Local: where you start DISPLAY.
- If you use '-f' command-line option, Global and Local config files
- are ignored. The specified file is used.
- 3. Process the command-line options (if any). So command-line options
- override the configuration file.
- 4. Now, RUN.
-
-
-
- (10) Menu
- =========
-
- GENERAL RULES
-
- This section will describe the menus and options you can choose from. You can
- read through it or just start the program and play around. When you have
- a problem you can come back and read the section you need.
-
- Most things are self-explanatory. Look for the comments behind a possible
- command. Also keep an eye at the first and last row of the screen: DISPLAY
- will tell you in most cases what is going on.
-
- There are several fields with a special meaning (i.e. [ Auto Read ]). You
- can activate them by moving the cursor inside the marks and then click the
- left mouse button.
-
- In any MENU you can call a pull-down-menu by pressing the F9 key or moving
- the cursor to the top-line and click a button.
-
- The different functions can also be selected by using a hot-key.
-
- Sometimes DISPLAY will ask you questions. You can answer them with a mouse
- click or by pressing the first (capital) letter of the answers
- (i.e. Y or y for yes).
-
- Allowed operations are shown in white the others in grey (if you use the
- default colors).
-
-
- -----------------------------------------------------------------------------
- THE READ-MENU
- -----------------------------------------------------------------------------
-
-
- After starting DISPLAY, you will find yourself in the read-menu. You will see
- a file list of the directory you started DISPLAY from (or the directory you
- have specified with the -t command line option). Which file information you
- see, depends on your selection in the config.dis file. You can choose from
- different informations (including 4DOS description files).
- There are some marked fields you can use with the mouse. In the pull down
- menu-bar you will find 8 headers with a different number of options. Because
- most operations are accessible with short-cuts, that's the easiest way to call
- them. For some operations (i.e. slide show) you have to tag at least one file.
-
- For Reading a file (image, movie) simply select one and press RETURN or double
- click with the left mouse button. Display will autodetect the correct format
- by itself. If you have problems try using the SPACE bar or double click with
- the right mouse button for selecting a format manually.
-
- When image dimension is shown, '*' means that this image is 24-bit. percentage
- means the compression ratio (file size/image size). Where image size is
- image_width * image_height * pixel_size(1 or 3).
-
- There is a status line at the bottom of screen. 'gamma' means gamma
- correction is used. 'desc' means file descriptions are changed. 'Hi' means
- using HiColor mode for preview.
-
-
- 1. HELP
-
- Here you find some informations about display and it author. You can choose
- the complete help (this file) and a short overview of key assignments.
- Calling help will load the DISPLAY.DOC file. It contains help about possible
- actions and a list of all short-cuts. There is also a description of the
- meaning of the mouse buttons (be sure to check them out, because they
- change, depending on the menu you use).
- The second file is user defined, so you can write whatever you want. The
- actual file brief.doc is just an example.
-
- 2. FILE
-
- You have several options to manipulate files. You can delete, move, copy,
- rename and view files. The options for shelling to DOS and quiting the
- program are also located under this header. You can perform the actions on
- a single file, a group of files (that is, tagged files), or the file
- currently under the marker.
-
- 3. DIR
-
- From inside DISPLAY you can make directories. Another point is rereading
- the current directory, for updating changes you have written to disk.
-
- 4. OPERATION
-
- That's the menu with the real highlights of DISPLAY. Here you can choose
- from the options: slide show, batch conversion, contact sheet, accumulate
- quantization, and the special effects. Further you can display the fonts
- comming with DISPLAY, show and write a already loaded image, and unpack
- gl-files. You can also create a .flc movie. For some operations, you must
- tag files first.
-
- 5. CHANGE
-
- Under this header you will find options to select the image type and
- graphic resolution (for a list of possible modes for your graphic card
- take a look at the status menu or type L). Other options are for changing
- the working-drive and for editing the file mask (see match.doc).
-
- 6. TAG
-
- Believe it or not this one is for tag and untag files (single, group, all).
- I think that's all you must know.
-
- 7. OPTION
-
- This menu point is for changing the defaults. Open the submenu and you
- will see a number of fields, where you can change most parameters that
- DISPLAY uses. You can activate them just for one run or make them the
- default by saving a new config.dis. You can work with different configur
- -ations, when you use different local config.dis files (i.e. make
- directories for the users of your system, if there is more then one).
- If you don't understand the meanings of parameters, please read config.dis.
-
- 8. STATUS
-
- Here you can get informations about your graphic card, RAM, disk space,
- and the formats of your image files.
-
-
-
- -----------------------------------------------------------------------------
- THE WRITE-MENU
- -----------------------------------------------------------------------------
-
-
- When you choose an option that will write changes to your disk, you will
- sometimes enter the write-menu (i.e. moving files). In the write menu you
- will find other marked fields for use with mouse. Although you will see the
- same headers in the pop-up-menu, most of the options are disabled. Also the
- most short-cuts won't help you. I think you will use this menu without
- problems, because it is very self-explanatory.
-
-
-
- -----------------------------------------------------------------------------
- THE SCREEN-MENU
- -----------------------------------------------------------------------------
-
-
- Once you have loaded a picture, you will see the screen-menu (if you don't
- set the 'auto_display_image' to 1). It has a different look and pop-up-menu
- structure. If the loaded file is a movie, you will find yourself in another
- menu, which is optimized for the additional needed options you need to
- display movies.
-
- The marked fields in the screen-menu are for viewing an image in the selected
- resolution or writing it to file. Further you can go back to the read-menu or
- exit the program. On the left you see three bigger fields. They are for those
- of you, who are using a mouse and don't want to use the keyboard for pressing
- the return, space, or esc keys.
-
- The graphic modes you can choose from (to show the image) are in white, the
- others are grey.
-
- Pressing F9 again will bring up the headers of the pop-up-menu. These have
- changed a little, compared to the read/write menu
-
- 1. HELP
-
- Same as in read/write menu.
-
- 2. FILE
-
- Only the exit option is still there, for the other things you have to go
- back to the read/write menu.
-
- 3. OPERATION
-
- Three options are now in the submenu. You can choose between special
- effects, display fonts, and change processing target. The last option
- means to change between palette images (most 8-bit images are of that
- type) and RGB-pictures (truecolor, highcolor).
-
- 4. OPTION
-
- Same as in read/write menu except for the preview option.
-
- 5. STATUS
-
- The possible graphic and text mode are shown here (depends on your
- hardware and the driver you use).
-
- 6. UTIL
-
- What you find in this submenu are some often used operations from the
- special effects menu (look there for a description of the comands).
- Another way to manipulate your image is the pop-up menu in graphics
- mode. There you can perform some effects without leaving the picture.
-

-
- (11) Special Effects
- ====================
-
- -----------------------------------------------------------------------------
- SPECIAL-EFFECTS-MENU
- -----------------------------------------------------------------------------
-
- When you start manipulating your pictures you will at some point look in the
- special-effects-menu. The different effects are sorted in 6 groups. As
- mentioned above you can rotate, flip, resize, mix, and convert images.
- Most often other programs offer only some of the operations DISPLAY is able
- to perform. Some other effects DISPLAY performs are otherwise found in
- professional and expensive graphic packages only!
-
- In this chapter you will find the complete list of possible effects with some
- short comments. The numbers are the same as in DISPLAY. If you want to make
- some of these effects the defaults for batch conversion please find the
- [Batch_Convert] section in config.dis and read the comment.
-
- At the end of this section are some more detailed explanations of selected
- special effects (marked with an '*'), don't miss them !!

- Detail Explanations of Special Effects
- --------------------------------------
-
- DISPLAY can store both 8-bit and 24-bit images in memory. If 8-bit image
- presents, 'Imag8' is shown in the screen mode/resolution selection scren.
- Otherwise 'NULL8' is shown. For 24-bit image, 'Imag24' or 'NULL24' is shown.
- If 'Imag8' or 'NULL8' is highlighted, all special effects are performed on
- 8-bit image, which is called processing target. Of course, error message is
- shown, if there is no 8-bit image ('NULL8' is shown). In general DISPLAY can
- make the best decision for you. You can also use TAB key to change the
- processing target. The general rule is:
-
- The processing target is always the newly saved image.
-
- If possible, DISPLAY keeps the target type. That is, after processing 8-bit
- image is still 8-bit. If it is not allowed, type tranformation occurs. For
- exmaple, 'Flip image' keeps the target type, while 'Quantization' converts
- 24-bit image to 8-bit image. The follow is the used symbols:
- -> 24 : Result is always 24-bit image(with some exceptions).
- -> 8 : Result is always 8-bit image.
- 8 -> 24 : This effect works on 8-bit image only and produces 24-bit image.
- 8 : This effect works on 8-bit image only. Image type is preserved.
-
- Some effects(or called operations) are easy to understand. Just do it and
- see the result. Some are difficult to understand. Here I make the detail
- explanations of some effects.
-
-
- (01)-(05) Rotate/Shear image (any angle)(->24)
- Antialias : The result looks more smooth.
- Background R,G,B : Used to fill the unused area in the result.
-
- (02)-(01) Resize image (->24)
- Image width, Image height : You can use '%' to specify the percentage
- relative to the original image dimension.
- Preserve aspect ratio : DISPLAY keeps the original width v.s. length
- ratio in the result.
- Smoothing : The result looks more smooth. If this
- opation is off, image type is preserved.
- Otherwise 24-bit image is produced.
- Resize method (for batch) : This option works for batch conversion only.
- Absolute : Image is resized to the specified size.
- Relative : Image is resized to the specified percentage
- relative to the original image.
- Bounded box : Image is resized to the specified bound box
- size. The result is always smaller than or
- equal to the bound box. Use 'Preserve aspect
- ratio' to control the aspect ratio.
- Fix width : If 'preserve aspect ratio', use the specified
- image width and adjust image height so that
- the new aspect ratio is the same as original,
- otherwise same as 'Absolute'.
- Fix height : Same as above but applied to height.
-
- (02)-(03) Mix/Concat two images (->24)
- This is the one of thw two effects that
- works on two images.
- Fore over Background(no w.) : Very simple. If the pixel in forground image
- is BLACK(that is, pixel value is 0), it is
- replaced by the corresponding pixel in
- background image.
- Background R,G,B : Used to fill the unused area in the result.
-
- (02)-(04) New Dimension
- This effect doesn't resize image, just change
- the image size. If the new size is smaller
- than original size, cropping is performed.
- Otherwise, unused area is filled with Back-
- ground R,G,B.
- For 24-bit image, the result is always 24-bit.
- For 8-bit image, if number of colors is greater
- than 256, the result is converted to 24-bit.
-
- (03)-(04) Color Quantization (24->8)
- This is the most complicated
- operation in DISPLAY.
- I recommend the 'Statistical' and
- 'Variance Based' methods.
- Fixed 256 : Worse quality, fast, always 256 colors.
- Median Cut : quality better than 'Fixed 256', slightly slow.
- Median Cut(Better) : The best quality of all, need LARGE memory,
- slowest. I don't recommend you the method.
- Grey 256 : Convert to grey, always 256 colors, fastest.
- Variance Based : Good quality, accetable time and memory
- comsumption.
- Statistical : Actually, I can hardly tell the difference
- between this method and 'Variance Based'.
- Current Palette : Useful if you want to produce images that use
- the same palette. Use 'display palette table'
- to show current palette.
- Ordered(fast) : The fastest method for color quantization.
- Need no additional memory.
- Neural Net(256) : Always 256 colors. The quality is controlled by
- 'neuquant_sample_factor' resource.
-
-
-
- (04)-(08) Remove unused colors (8)
- This effect trys to remove unused and
- duplicated colors from 8-bit image.
- It can decrease the number of colors.
-
- (04)-(10) General convolution (-> 24)
- I think that mathematical expression is
- more clear:
- _ _ _ _
- | (x-1,y-1) (x ,y-1) (x+1,y-1) | | K0 K1 K2 |
- A = | (x-1,y ) (x ,y ) (x+1,y ) | , B = | K3 K4 K5 |
- | (x-1,y+1) (x ,y+1) (x+1,y+1) | | K6 K7 K8 |
- - - - -
- new pixel at (x,y) = (sum all A(i,j) * B(i,j)) / overall_divider
-
- For those without matrix knowledge:
- Think of A as a picture.
- 1 1 1 The B matrix are the 9 values you can fill
- 1 1 1 in the Kernel fields. The multiplication of
- 1 1 1 two matrices (which must have the correct
- row and column size) results in a single value.
- R R R Now imagine that 'picture' A (3x3 pixel)
- G G G 3xR+3xG+3xB consists of colored lines (i.e. Red Green Blue)
- B B B and all K-values in B equals '1'.
- You'll get a new center pixel, which is bright
- 3 red + 3 green + 3 blue white. If you set the overall divider to 50
- the resulting pixel will be grey (dark white).
- So as a result you will mix-up the colors of
- your picture. The divider sets the brightness.
-
- (02)-(06) Make image translation (->24) (documented by Bernhard Maerz)
- ----------------------------------------
- This is a very powerfull tool to make nice effects by changing of the
- brightness. There are much different ways possible to change the brightness
- and secondary there could be used a maskfile to use different methods on
- different parts of the picture.
-
- Foreword:
- three numbers separated by a '/' are RGB values:
- i.g. 30/60/0 are Red=30, Green=60 and Blue=0
-
-
- First, there should be explained how the brightness would be changed.
- For this thing, there exist a 256x256 image (called TABLE), which tells how
- to do it. You can select Your own table or You can use one of the tables
- directly implemented in DISPLAY (read display.faq for the formulas) :
- - User defined table (from stack)
- - Brightness adjust
- - Contrast adjust
-
- Before You read the following, You could take a small look on one of the
- implemented tables with the option (in the mask image translation menu):
- Display mask table in graphic mode
-
- You will see a 256x256 image. Each defined method of changing the brightness
- needs ONE HORIZONTAL LINE. Because there are 256 lines, there are 256 WAYS
- of changing the brightness.
-
- Let us look at an example to explain how it work: the implemented brightness
- table. The upper and the left numbers are only for help and are not saved in
- the tablefile. The numbers in the table are set by colors:
- (The value along Y axis is taken from mask, while the value along X axis
- taken from original image)
-
- black for 0 - white for 255
-
- # 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16

-
-
- This table contains 256 ways of changing the brightness. Let us look at
- one of them. For example, take a look at line 64. This line contains
- 256 numer of values.
- For EACH OLD BRIGHTNESS VALUE are standing the NEW VALUE OF BRIGHTNESS.
-
- When the brightness is changed, this will be done separately with
- Red, Green and Blue.
-
- The line 64 'says' the following:
- For EACH Red, Green, Blue value it will be changed
- from 0 to 0
- from 1 to 0
- from 2 to 1
- from 3 to 1
- from 4 to 2
- ans so on.
-
- So here are a few examples:
- The color 6/0/1 will be changed to 3/0/0
- the color 6/9/0 will be changed to 3/4/0
- the color 4/7/5 will be changed to 2/3/2
-
- For each pixel, You can specify 3 different mask values for R, G, and B,
- respective. For example, you can use masks 0, 128, and 255. Therefore
- red component is changed to 0, green component is not changed, and blue
- component is changed to 255.
-
- If You have carefully lookd at the table, You would have remarked that the
- line 128 doesn't change anything. And if You have take a better look, You
- would know what the 256 methods would be done:
-
- Brightness adjust table
- Methode
- 0 Darken the image to fully black
- ... Darken the image
- 128 Doesn't change the image
- ... Lighten the image
- 256 Lighten the image to fully white
-
-
- And this is the first easy way to use this option. You can simple select
- the option
- 'Where to get Mask User input'
- and then You can say with
- 'Mask value (user input)'
- which of the 256 methods should be used. You can specify three different
- mask values for R, G, and B, respective. Then the whole picture would be
- changed with these methods specified by the three masks.
-
- If You select the Brightness adjust table and the mask value of 100, the
- image would be a bit darken. Have You selected 70 instead, the picture would
- be a bit more darken.
-
- Maybe You ask, You could have done that allready with DISPLAY (but not with
- different strengthness). But with this table You are much more flexible.
- So You could make a table which will lighten only the dark parts of the
- picture. Such a table could look like the following:
-
- 0 ... 30 ... 60 ... 90 ... 120 ... 150 ... 180 ... 210 ... 240 ...
- #########################################################################
- . #
- 128 # 0 ... 30 ... 60 ... 90 ... 120 ... 150 ... 180 ... 210 ... 240 ...
- . #
- 160 # 0 ... 70 ... 95 ...120 ... 145 ... 170 ... 195 ... 220 ... 245 ...
- . #
- 192 # 0 ...110 ...130 ...150 ... 170 ... 190 ... 210 ... 230 ... 250 ...
- . #
-
- The method in line 192 says the following:
- 30/0/0 will be lighten by +80 to 110/0/0
- 60/0/0 will be lighten by +70 to 110/0/0
- 90/0/0 will be lighten by +60 to 150/0/0
- ...
-
- But furthermore, the option 'Mask image translation' could be made even
- more.
-
- It's not only possible to say what method should be used by the option
- user input, it's possible to use different methods in one process by
- defining a mask file.
-
- This mask file should have the same size as the image to process, but
- there is no need to make this manually, because DISPLAY resizes it
- automatically. But if the size of the mask file is very small (relatively
- to the picture), the size should be increased a bit manually (with smooth),
- because DISPLAY resizes it directly while processing the 'mask image
- translation' and can't so use any smoothing.
-
- Then DISPLAY takes each pixel from the original picture (which should be
- changed) and takes the pixel from the mask picture from the same position
- (tells the methode) and makes the changes like defined.
-
- For this I will make a small example which uses again the brightness adjust
- table.
-
- The mask file could look like the following.
-
- 0 10 30 10 0
- 10 40 60 40 10
- 30 60 128 60 30
- 10 40 60 40 10
- 0 10 30 10 0
-
- With such a mask file (and brightness adjust table) the orignal picture
- will be stay in the center, but it will be become more darker to the edge.
-
- In the text above, I have allways written ONE number in the table and mask
- file. This means all changes done for Red, Green and Blue are the same. But
- You can use RGB images as masks, too, and then the changes are different.
-
- You can use RGB or 8-bit image as table (palette is discarded). Finally,
- the mathematical equation is given below (for 24bit mask and table):
-
- new_pixel[x,y].r = table[ old_pixel[x,y].r , mask[x,y].r ].r
- new_pixel[x,y].g = table[ old_pixel[x,y].g , mask[x,y].g ].g
- new_pixel[x,y].b = table[ old_pixel[x,y].b , mask[x,y].b ].b

- (13) About the author
- =====================
-
- I am a student in National Chiao-Tung University, Taiwan, R.O.C.. Why do I
- write DISPLAY ? Because I can't find any viewer in DOS world which can fulfill
- my needs. I want to have a viewer for my personal use, so that I can do any
- experiment I want to do. It is obvious that the easiest and best way is to
- write a viewer by myself.
-
- The first thing I think of is which compiler I should use. Turbo-C ? No, I
- don't want to bother with segment and offset any more. Watcom-C ? No, I don't
- have money to buy it. DJGPP ? YES, it is a 32-bit C compiler with good
- reliability becuase the engine is GNU C compiler. The most important reason is
- that it is FREE.
-
- I develop DISPLAY on 486DX-33 with 16MB ram, So memory is not a problem. I
- decide to write program in UNIX style, because DJGPP emulates the UNIX
- environment. Thanks to the virtual memory function in DJGPP, I don't need to
- worry about the memory allocation. In the initial stage, I just write DISPLAY
- for my persion use. Finally, I want to hear others' opinions, so I release it
- to the Net. Many people give me suggesitons, encouragement and bug reports.
- They all help to keep DISPLAY growing. The role of DISPLAY also changes from
- plain viewer to multi-purpose viewer. Now DISPLAY is not just my program
- because it includes many ideas from the users.
-
- DISPLAY source code size : 156 files, 77927 lines, 2560246 bytes.
- Including : ZIP code.
- Not including : MPEG player, JPEG and TIFF library.
-
- Finally, if you think that DISPLAY is good enough and would like to write a
- postcard to me, my physical address is :
-
- Room 1410, Graduate Student Dorm., National Chiao-Tung University,
- Hsin-Chu 300, Taiwan, R.O.C.
-
- My room (above address) will change after September 1995. If you want to
- mail me without knowing my new address, you can mail to:
-
- Institute of Electronics, Engineering Building 4, National Chiao-Tung
- University, Hsin-Chu 300, Taiwan, R.O.C.
