- PicView 0.9beta
- An alternative picture Viewer
- Copyright 1989 by Greg Thomas & Brad Mettee

- What is PicView?
-
- PicView is an alternative picture viewer that offers features
- not found in any other Picture viewer elsewhere. This is not the end
- all program (yet). Other viewers do offers some features that PicView
- does not, such as graphic conversion. Some of the 'deficiencies' of
- PicView will be added to later releases.
-
- Currently PicView will read and display 2 graphic formats.
- These are GIF and MAC formats. We are currently working on
- implementing more formats, notably RIX SC? files, PCX and Deluxe Paint
- LBM files. Other formats are being looked into, and will be
- implemented as we accrue information on them. (As well as a
- proprietary format that contains information for PicView.
-
-
-
-
- What makes PicView different than these other viewers?
-
- Ahh glad you asked that question (you did ask that, didn't
- you?) Well, for starters, our biggest pride with this product is the
- superb ADJUSTABLE palette animation. A picture can be animated
- through the entire palette, a portion of the palette, and through a
- range of colors in the palette. The effects of the animation must be
- seen to be truly appreciated.
-
-
- It also sports a very easy to use window interface that if not
- for the complex animation abilities, would preclude the need for docs
- at all. It uses very easy pop-down windows for all parameter setting
- and selection very similar to the environments used in Borland's
- Language's (Guess will have to look out for the look and feel police.)
-
-
- Currently, it supports the SVGA (or EVGA if you prefer) modes of
- the ATI VGA wonder and small wonder. It will auto detect if these
- adapters are installed, and adjust the mode selections (screen size)
- accordingly. Other chip sets such as Vega, Tseng, Paradise, etc. are
- on the way, and should be ready shortly. Also, for you True Blue
- users, a special 360x480x256 mode is in the works for you to get
- almost SVGA performance out of your motherboard VGA (expect this to be
- in release 1.0 shortly). PicView currently (and most likely won't
- ever) does NOT support standards less then VGA. There are several
- viewers on the market that support EGA and below, so it seemed rather
- pointless since PicView's animation abilities are best done on VGA.

-
- PICVIEW.GIF PicView.gif is a gif file which
- demonstrates the viability of partial
- palette animation. Using the random
- palette (any palette will do, but works
- best with random or plasma) set starting
- register to 92, and end register to 112.
-
- WAVE.GIF Wave.gif and boxes.gif both have
- BOXES.GIF continous smooth palettes making
- experimentation of the default palette's
- possible settings.
-
-
-
-
- In the Works
- Some of the features that PicView will be incorporating in
- future releases are:
- 360x480x256 for IBM and all register compatible VGA cards.
- A script language for slideshow presentations.
- Support for other SVGA cards.
- Support for more file formats i.e. PCX, LBM, etc.
- Hot key access to menu choices.

-
- Getting Started with PicView
-
-
- To start PicView, simply type pv at the dos prompt. A credit
- screen will pop up, and after a short pause, will take you to the main
- menu. From the main menu, you have 5 choices, detailed here.
-
-
-
-
- Info
-
- Pops up the opening credit screen. (In case you get bored, or
- want to know who wrote this contraption.)
-
-
-
- File
-
- Pops up a sub menu used for file selection.
-
-
-
- Environ
-
- Pops up submenu for options pertaining to environment.
-
-
-
- Options
-
- Brings up a submenu to select PicView's options.
-
-
-
- Exit
-
- Exits the program. (That's a hard one to figure out, eh?)
-
-
-
-
- Submenus have a varying number of selections that either pop up an
- additional submenu, prompt you for data, or display a selected file.
- Submenu options will be detailed here.
-
-
-
-
- File
-
- Select File(s)
-
- This selection pops up a file selection window which allows
- you to select the file to be viewed. The window sports a scroll
- bar to give you an indication of how far along you are in the
- list of files. There is a real file limit of 16,000 files that
- can be read into the directory (assuming you have a 640k
-
-
-
- machine). You can use first character selection to speed you
- through your files. Hitting 'T' once will take you to the first
- file beginning with T. Hitting it again will take you to the
- next and so on. The list can be scrolled beyond the end or
- beginning if scrolling in reverse. When you find the file you
- want to display, Hit the 'ENTER' key and it will be displayed.
- After the file has been displayed, strike any key to return to
- the file selection window. When you return, you will have the
- last file displayed still highlighted.
-
-
- File Type
-
- This selection will pop up a little window that allows you
- to select which type of file you wish to have in the selection
- window above. Currently you have two choices, GIF and MAC.
- This will be expanding in the near future.
-
-
- Environ
-
- Screen
-
- This will pop up a submenu allowing you to select which
- screen mode you want the picture displayed in. Depending on
- your video adapter, you may not be able to select all of the
- choices. If you have an ATI VGA Wonder with 512k, you can
- select from any mode, including the Auto select option which
- will let the program select the best video mode for the picture
- to fit in.
-
-
- Options
-
- Animate
-
- This will pop up a window prompting you for data to control
- the animation facilities of PicView. The first data item you
- are prompted for is whether or not you want animation on. If
- you select 'N', the window is dropped, and you are returned to
- the next level up menu. If you select 'Y', you are then
- prompted for the direction, palette, starting and ending
- registers, and depending on the palette selected, starting and
- ending color data. More detail will be covered on this topic
- later.
-
-
- Exit
-
- This selection returns you to DOS. Optionally, you can hit the
- escape key at any top level menu to return to dos as well.
-
-
-
-
- OK, Let me go into some details on the animation options, as
- some of it can be a bit confusing.
-
-
- After selecting 'Y' to the animate prompt, your next prompt will
- be for the direction to animate. View both, as the different
- directions can have an entirely different effect. The direction is
- relative, and can/will be different from file to file (dependent on
- how the palette registers were laid out at the time the file was
- created).
-
-
- The next prompt after selecting the direction, will be for you
- to select the palette. You have 3 choices here, a random palette, the
- default palette, and a plasma palette (based loosely on the demo
- plasma). Use experimentation here, as different images work better
- with different palette selections. The random palette will look
- pretty good for just about any image (note: images with smooth
- palette ranges animate the best). If the default palette is laid out
- well without many 'holes', this one works well too. Although, I have
- viewed some images that DO have 'holes' which enhanced the animation
- effect. The plasma palette is based on a smooth transition of red,
- green and blue and restricts the animation to the first 180 or so
- registers (again, based loosely on the images created by the demo
- plasma).
-
-
- If you select the Default palette, a window will pop up
- prompting your for starting and ending color. This will be discussed
- in the next section as it is related to registers, but only applies to
- the default palette.
-
-
- OK, I trust you've kept up with me so far. Here's where it can
- get confusing. Your next prompt is for the starting and ending
- color. If you've selected either the Random or Plasma palette, this
- will tell the program which color register to start the animation at,
- and which to stop it at. This gives you the ability to animate a
- portion of the image, instead of the entire image. This works VERY
- well for images that use a smooth palette range in a portion of the
- picture.
-
-
- Now, if you've selected the Default palette, your start and end
- colors take on additional meaning in conjunction with the start and
- end color window that popped up after you selected DEFAULT. To give
- you a better understanding, picture your image like this. Every pixel
- gets its color from one of 256 palette registers. The start and end
- registers are exactly that, PHYSICAL registers in the machine. The
- start and end colors are the color data contained in those registers.
- When you select your start and end register, you are selecting the
- physical registers that are scrolled. When you select the start and
- end color, you are selecting the range of color data that you want
- scrolled through those registers. If you select a color range smaller
- than the palette range, the number of colors you selected will
- determine the number of registers scrolled. However, if you select a
- smaller range of registers than colors, then the registers will scroll
- through the entire range of colors you selected
-
-
-
-
- OK, are you thoroughly confused? I thought so, but experiment a
- little after reading the docs (preferably with the images that came
- with the PicView file since they have smooth palette ranges, it makes
- it clear sooner what exactly is going on).
