ΓòÉΓòÉΓòÉ 4.1. Object of SBSVIEW ΓòÉΓòÉΓòÉ

The object of SBSVIEW is to display and export images in various formats.

SBSVIEW has several capabilities for image processing such as filtering, gamma
correction, resizing, flipping and rotating.

You can display the images in full screen mode, in original size or in window
size with keeping the image aspect view or not.

Because we're very interested in fractals, we have developed a fractal
compression format. A few examples of fractal compressed images (unfortunataly
only in 8-bit grayscale color) are in the package. Try then and compare then
with the JPEG's.

We have implemented a slideshow with the usual option as display the selected
files in forward, reverse and random order with a cycle option . You can choose
if you want to load the next file timed or manual. Because we does'nt like the
random order in other slideshows (the files were selected over the whole image
pool) we have implemented an option where you can specify the range of the
image pool in percent in which you want to select then next file from the last
loaded image.

See working with SBSVIEW to get an introduction to handle the capabilities of
SBSVIEW .

ΓòÉΓòÉΓòÉ 4.3. Helpfull Hints ΓòÉΓòÉΓòÉ

o If you can only display 8-bit color depht in your PM applications, you should
  turn off the 24-bit color depht in the Load Options.
o If you display JPEG images in 8-bit color depth you should use the 2-Pass
  decoding Option to get better images, but the decoding is a little bit
  slower.
o many functions you can select from the menu you can faster access with the
  mouse. See Working with the mouse for furthr information.


ΓòÉΓòÉΓòÉ 4.4. Working with the mouse ΓòÉΓòÉΓòÉ

The mouse buttons have various functions depending on the state SBSVIEW is in.
Left mouse button:

o if you have loaded an image you can select an rectangle of the image by
  pressing the left button at the first position, draging to the second
  position by let the button pressed and then release the button. This
  rectangle can be used to zoom and to crop this part of the image.
Right mouse button:

o if you have loaded an image and the image isn't zoomed the right button can
  be used for loading the next file in the current directory.

o if you have selected an rectangle as described at the top the right button is
  used for zooming this part of the image.

o if you have started a slideshow and the current image isn't zoomed the right
  button is used to end the slideshow. When the image is zoomed or a rectagle
  is selected then the right button is used as described before.


ΓòÉΓòÉΓòÉ 5. Help for Aspect ΓòÉΓòÉΓòÉ

If the menu entry Aspect is checked then the image is displayed by keeping the
aspect ratio of the original image size. If not the image is displayed in the
size of the window.


ΓòÉΓòÉΓòÉ 6. Help for Original Size ΓòÉΓòÉΓòÉ

If the menu entry Orig. Size is checked the image will be displayed by its
original size. Because an image can be greater then the window in wich it is
displayed, we've added sliders to make it possible to view the whole image. If
the menu entry is not checked the image will be displayed to fit the window.


ΓòÉΓòÉΓòÉ 7. Image Formats ΓòÉΓòÉΓòÉ

SBSVIEW can display and save images in various image formats. The supported
formats for loading are Windows and OS/2 BMP, FRACT, GIF, JPEG, PCX and TIFF .
The supported formats for saving are OS/2 BMP, GIF, JPEG and TIFF. Support for
other formats is in progress. Look for the latest version of SBSVIEW. Related
information:

o BMP format

o FRACT format

o GIF format

o JPEG format

o PCX format

o TIFF format


ΓòÉΓòÉΓòÉ 8. BMP format ΓòÉΓòÉΓòÉ

SBSVIEW can view Windows and OS/2 (1.x and 2.0) BMP files stored with 1, 4, 8,
or 24 bits per pixel and can view BMP files that are run-length encoded(RLE).
In addition, it can display the first image in an OS/2 bitmap array. It can
save uncompressed Windows or OS/2 BMP files in 1, 4, 8 or 24 bits per pixel.


ΓòÉΓòÉΓòÉ 9. FRACT format ΓòÉΓòÉΓòÉ

FRACT is a fractal compression format based on quadtree the image recursive.
It's an experimental method we're developing on.


ΓòÉΓòÉΓòÉ 10. Display Warnings ΓòÉΓòÉΓòÉ

If the menu entry Display Warnings is checked SBSVIEW shows all warnings and
errors, wich occurs during decoding the images. If you get only a warning
SBSVIEW tries to correct or ignore the warning and make further processing. At
an error it will stop decoding and let you selectt anothher image. If it isn't
checked SBSVIEW shows only errors, wich occursduring decoding. These are errors
SBSVIEW can't correct.


ΓòÉΓòÉΓòÉ 11. Help for Encode Options ΓòÉΓòÉΓòÉ

In the Encode options dialog you can specify the compression subformat for the
image format you want to save with.

The following image describes the Encode Options:

At the JPEG Options you can select the quality you want to save the image to.
Since JPEG uses a lossy encode algorithms the default quality of 75 percent is
a good decision between the quality of the rersulting picture and the filesize.

At the Gif Options you can select if you want to save the picture as interlaced
gif of if you want to save the gif with a transparent background.

At the TIFF compression options you can determine how SBSVIEW saves TIFF files.

o Compression - Bilevel Images This lets you choose compression method for
  Bilevel (Black/White) images. -  None No compression is used - Packbits use
  Apple Macintosh PackBits compression scheme -  LZW use LZW adaptive
  compression scheme -  Group 3 bilevel use CCITT Group 3 facsimile encoding
  scheme -  Group 4 bilevel use CCITT Group 4 facsimile encoding scheme

o Compression - Color Images This lets you   choose compression method for
  Color images. -  None No compression is used -  Packbits Use Apple Macintosh
  PackBits compression scheme -  LZW Use LZW adaptive compression scheme
For more information on these options, please refer to the TIFF 6.0
specification avaliable from Aldus Corporation.


ΓòÉΓòÉΓòÉ 12. Help for JPEG ΓòÉΓòÉΓòÉ

This package contains software to implement JPEG image compression and
decompression. JPEG (pronounced "jay-peg") is a standardized compression method
for full-color and gray-scale images.  JPEG is intended for compressing
"real-world" scenes; cartoons and other non-realistic images are not its strong
suit.  JPEG is lossy, meaning that the output image is not necessarily
identical to the input image.  Hence you must not use JPEG if you have to have
identical output bits.  However, on typical images of real-world scenes, very
good compression levels can be obtained with no visible change, and amazingly
high compression levels are possible if you can tolerate a low-quality image.
This software implements JPEG baseline and extended-sequential compression
processes. Provision is made for supporting all variants of these processes,
although some uncommon parameter settings aren't implemented yet.  For legal
reasons, we are not distributing code for the arithmetic-coding process; see
LEGAL ISSUES.  At present we have made no provision for supporting the
progressive, hierarchical, or lossless processes defined in the standard.
(Support for progressive mode may be offered in a future release.)

ΓòÉΓòÉΓòÉ 13. Help for TIFF ΓòÉΓòÉΓòÉ

SBSVIEW supports a subset of the TIFF 6.0 specification.  SBSVIEW can view TIFF
files stored with 1, 4, 8, or 24 bits per pixel.  SBSVIEW can read TIFF images
stored in strip format, in which the image is divided into horizontal strips of
pixels, and tile format,  in which an image is divided into rectangular grids
of pixels.  The compression modes LZW, Packbits, Thunderscan, NeXT, and CCITT
(RLE, RLEW, FAX3, FAX4) can be read as well as uncompressed TIFF images.

SBSVIEW can save uncompressed or Packbits-(Macintosh RLE), LZW-(with or without
differential encoding), CCITT Group 3-, or CCITT Group 4-compressed TIFF files
with 1, 4, 8 or 24 bits per pixel.  TIFF files are saved in strip format.

ΓòÉΓòÉΓòÉ 17. Help for slideshow options ΓòÉΓòÉΓòÉ

The following image describes the Slideshow options:

If you want to start a slideshow you can select between several Options:

o Cycle  When a slideshow is running, the Cycle option determines whether or
  not a list of images is continuously displayed in a cycle.  If this option is
  on, the slideshow returns back to the first picture after the last one is
  displayed and continues to display all the images in a selected list until
  you abort the slideshow.

o Forward/Backward  The Slide Order determines the order in which the images in
  a slideshow list is displayed. If forward order is selected,  the images are
  displayed in the order in which they are listed in the slideshow dialog box.
  If backward order is chosen, the images are displayed in reverse order from
  the last file to the first one in the slideshow list.

o Random  If you choose the random order SBSVIEW will select an image out of
  the filelist. The selection of the image depends on two factors. First if you
  have choosen forward order SBSVIEW will select an image in the order in wich
  they are listed in the slideshow list. If you have choosen backward order
  SBSVIEW will select an image in reverse order. Because we does'nt like the
  random order in other slideshows (the files were selected over the whole
  image pool) we have implemented an option where you can specify the range of
  the image pool in percent in which you want to select then next file from the
  last loaded image.

o Randomsearch  In this entry field you can enter the range in wich you want to
  select an image in random order.

o Manual  The Slide Advancement options determine how to advance to the next
  image in a slideshow.

  In manual mode, SBSVIEW will wait until you click with the right mouse button
  before advancing to the next picture.

  In Automatic mode, there will be a user-selected time delay before the next
  picture is loaded.

  To advance to the next picture before the delay has elapsed, press the N or
  the space key. The Delay can be set to a value between 0 and 60 seconds.

o Time  In this entry filed you enter the time delay before the next picture is
  loaded. To advance to the next picture before the delay has elapsed, press
  the N key. The Delay can be set to a value between 0 and 60 seconds.

o Show Container  If you choose the show container option an then start a
  slideshow you get a panel with status informations for the slideshow. The
  panel displays the current index and the number of images selected for the
  slideshow, the path of the current image and a listbox in wich all selected
  images are displayed by path and name.
Use OK to use the selected options. Use Cancel to discard your selection.


ΓòÉΓòÉΓòÉ 18. Help for cycle ΓòÉΓòÉΓòÉ

When a slideshow is running, the Cycle option determines whether or not a list
of images is continuously displayed in a cycle.  If this option is on, the
slideshow returns back to the first picture after the last one is displayed and
continues to display all the images in a selected list until you abort the
slideshow.


ΓòÉΓòÉΓòÉ 19. Help for forward/backward ΓòÉΓòÉΓòÉ

The Slide Order determines the order in which the images in a slideshow list is
displayed.  If forward order is selected,  the images are displayed in the

ΓòÉΓòÉΓòÉ 28. Help for Decode Options ΓòÉΓòÉΓòÉ

The decode options are applied when Maximum Color Depth is set to 8-bits.
2-pass quantization(specifically, Heckbert) calculates the optimal colormap for
the quantized image and produces better looking output than 1-pass
quantization. 1-pass quantization is slightly faster because a fixed colormap
is used. The other options select which decompression algorithm is used. Float
will be the best but the slowest. The best solution for an 8-bit color display
will be to select the 2-pass and the float option.

The following image describes the Decode Options:
