- INTRO
- =====
-
- CRUMBLER is a SIRDS (Single Image Random Dots Stereogram) and SIS (Single
- Image Stereogram) generator, able to render "TRUE-DEPTH" holusions.
-
- Crumbler 1.x & 2.0 are totally BATCH oriented, so they run using an
- extended command line.
-
-
- SYNTAX
- ======
-
- > CRUMBLER <input[.TGA]> <output[.TGA]> [+<options>]
-
- Input and output are TARGA files; input file can be either compressed or
- uncompressed, 256 gray-shade or 256 indexed coloured or 24 bit truecolor.
- The output is ALWAYS truecolor 24 bit, it can be compressed or uncompressed.
-
-
- PARAMETERS
- ==========
-
- Symbol "+" activates the specified option; when CRUMBLER checks the command
- line, prints "+<opt.>" for explicated options, while prints "-<opt.>" to
- show other Default values.
-
- Here are the options:
-
- "+p<pattern[.TGA]>" tells the program to create a SIS and <pattern.TGA> is
- the pattern file you want to superimpose to the Stereogram (it
- can be either compressed, uncompressed, 256c, 256g, 24 bit)
-
- "+b" is NOT compatible with "+p<>", neither with "+g". Tells to generate
- BLACK & WHITE SIRDS (so it doesn't need a pattern file)
-
- "+g" is NOT compatible with "+p<>", neither with "+b". Tells to generate
- a GRAY-SHADE SIRDS.
-
- "+dXXX" tells the input image depth-level. Means the way to read the colours:
- each colour represent a "depth-level" in the output image.
- Valid values are:
-
- "+d256" : 256 gray-values (Default) (SUGGESTED)
- "+d768" : 256(RED) + 256(GREEN) + 256(BLUE)
- "+d4069": RED*16 + GREEN + BLUE/16 (from 3D programs)
- "+d64k" : smoother images from 3D programs (SUGGESTED)
- "+d16m" : top number of depth-levels
-
- "+d256" is the easiest way to use CRUMBLER. The BRIGHTER pixels
- becomes THE NEAREST to you in the output stereogram, while
- the DARKER becomes the farther.
-
- "+r" is the RESOLUTION in DPI. Default=72 DPI, it depends on your output
- device. This is NOT compatible with "+w" option.
-
- "+w" is the MAX distance between two repeated patterns. This option can
- replace the "+r" one and it's NOT compatible with.
-
- "+z" is the Depth of Field. Values greater than 1.0. "+z1.0" generates
- the DEEPEST stereogram, while values greater than 10.0 generate
- 'flat' stereograms. Default = 2.0 for Wall-eye, 4.0 for Cross-eye.
-
- "+INT" uses a classical INTEGER algorithm to generate SIS & SIRDS.
- Use this option for "flat" stereograms, which don't need to appear
- smoothed.
-
- "+c" generates CROSS-EYED stereograms (WALL-EYED is by Default)
-
- "+sXXX" cuts the stereogram into "XXX" slices and invert them.
-
- "+o" overwrites existing output files.
-
- "+RLE" writes output compressed.
-
-

- QUICKSTART: Examples
- ====================
-
- Let's check a command line and say what it does:
-
- CRUMBLER in.tga out.tga +ppatt.tga +d256 +r60
-
- creates a SIS by using "PATT.TGA" as pattern file, and consider a
- gray-shade input image (IN.TGA), by producing a "true-depth" stereogram
- (OUT.TGA) of 60 DPI.
-
-
- CRUMBLER in out +b +int +RLE
-
- creates a black & white SIRDS by using an INTEGER algorithm (non true-depth)
- and saving "OUT.TGA" with RLE compression. Input file "IN.TGA" is considered
- 256 gray-shade, by Def.
-
-
- CRUMBLER i o +g +s18 +w100
-
- creates a gray-shade SIRDS by repeating a random pattern of max. 100 pixels
- per raw, and cuts it into 18 inverted slices.
-
-
- CRUMBLER i o +pp +c +o
-
- overwrites "O.TGA" if already exists and creates a CROSS-EYED SIS.
-
-
- CRUMBLER in ou +d64k +r100 +z1.5
-
- creates a coloured SIRDS (resolution = 100 DPI) quite deep, by using an image
- from a 3D program like 3D Studio.
-
-
- CRUMBLER i o +pp +d64k +r80 +s32 +c +o +RLE
-
- creates an 80 DPI cross-eyed SIS from a 3D image, cuts it in 32 slices,
- reverse them and then overwrites "O.TGA" and writes it compressed.

- INPUT IMAGES
- ============
-
- ===>
- ===> CHECK CRUMBLER.DOC TO SEE HOW TO CREATE 3D-IMAGES!

-
- ===>
- ===> CHECK CRUMBLER.DOC TO SEE HOW TO CREATE INPUT-IMAGES TOO!
- ===>
-
- Anyway, start drawing a simple WHITE shape (like a filled square or a
- circle) on a BLACK background, then try changing the BRIGHTNESS (using
- simple gray values is the easiest way, to use with "+d256" option) to see
- changes in the depth of the planes.
-
- Then try writing (BIG FONTS) with gray shades, then more complex
- pictures.... In this way you can easily learn by experience.
-
- ALWAYS check sample files to see how the input images should be.
