JP2A AmigaOS 4.0 Read Me ------------------------ jp2a is a small utility that converts JPG images to ASCII. It's written in C and released under the GPL. Important Note about the AmigaOS 4.0 port, it was not compiled with libcurl support, so you can't convert images directly from the net. I'll implement that in the future if LibCurl gets ported to clib2. Example Usage: jp2a --size=60x60 jp2a.jpg --output=jp2a.txt gives you this; MMMMWNWMMMMMMMMMMMMMMMMMMMMMMMMMMWNNWMMMMMMMMMMMMMMMMMMMMMMM MMMMWXNMMMMMMMMMMMMMMMMMMMMMMMMMMNXKNMMMMMMMMMMMMMMMMMMMMMMM MMMMOclXMMMMMMMMMMMMMMMMMMMMMMMN0oc:lkXMMMMMMMMMMMMMMMMMMMMM MMMN; dMMMMMMMMMMMMMMMMMMMMMWOc' .:KMMMMMMMMMMMMMMMMMMMM MMMK. :MMMMMMMMMMMMMMMMMMMMMk. cWMMMMMMMMMMMMMMMMMMM MMM0. :MMMMMMMMMMMMMMMMMMMMW; .OMMMMMMMMMMMMMMMMMMM MMMN, oMMMMMMMMMMMMMMMMMMMMN' cNMMMMMMMMMMMMMMMMMM MMMM: xMMMMMMMMMMMMMMMMMMMMN' ,KMMMMMMMMMMMMMMMMMM MMMMk:lKMMMMMMMMMMMMMMMMMMMMN' .. .OMMMMMMMMMMMMMMMMMM MMMXOkOKWMMN0000XW0xxOXMMMMMN' ;okx; .dMMMMMWXkxxxOXWMMMM MMWd''':KMMk''''dd'...;OMMMMN:oKMMM0. dMMMW0o;.....;kWMMM MMWc .0MMo ..

COLORED IMAGES You can also make coloured HTML images. They use CSS however, so currently we can't display them correctly with Amiga Browsers. --html Make ASCII output in strict XHTML 1.0, suitable for viewing with web browsers. This is useful with big output dimensions, and you want to check the result with a browser with small font. --html-fill When used with --html and --color, then color each output character's background color. For instance, if you want to use fill-output on a light background, do jp2a --size=60x60 --color --html --html-fill --background=light somefile.jpg --output=dark.html To do the same on a light background: jp2a --size=60x60 --color --html --html-fill --background=dark somefile.jpg --output=light.html The default is to have fill disabled. --html-fontsize=N Set fontsize when using --html output. Default is 4. --output=... Write ASCII output to given filename. To explicitly specify standard output, use --output=-. -i --invert Invert output image. If you view a picture with white background, but you are using a display with light characters on a dark background, you shoudl invert the image. --red= ... --green= ... --blue= ... When converting from RGB to grayscale, use the given weights to calculate luminance. These three floating point values must add up to exactly 1.0. The default is red=0.2989, green=0.5866 and blue=0.1145. SIZE --size= WIDTHxHEIGHT Set output dimension. FINAL WORDS For a deeper understanding of how this app works look in the source/man/ drawer for a indepth usage guide that unfortunately is in the unix man format.
