- ... version 0.8 by ma.ke. 2017-05-08 is a tcl package for windows
- ... is a hobby project with no warrenty
- ... can create animated GIFs from tcl/tk photo images
- ... is based on AnimGifC (animation feature) by Hubert Dryja hubertdryja@gmail.com
- ... is based on gifsave.c by Sverre H. Huseby sverrehu@online.no (see github)
features:
- standard functions of AnimGifC
- add simple standard vga palette of 16 colors
- add function to define default color
- add function to get color palette of an image
compile:
- to compile tclgif you need gcc and the header files of tcl/tk 8.3.x or higher.
- i use gcc 4.8.3 32bit and tclkit 8.40 under Windows 10.
- you can use the simple batch file compile_tclgif.bat and change it for you.
general working steps in wish (tk shell):
1. create gif stream
2. define colors and default color
3. add images (first add starts animation mode)
4. close gif stream
commands for working steps:
tclgif::new name width height res(bits) pal(bits)
tclgif::colput index r g b --> set color, get r,g,b values
tclgif::coldef index --> set default color, get r,g,b values
tclgif::add image delay --> add image, get frame and udf rgb color list
tclgif::close --> close gif stream, get last frame number
commands for informations:
tclgif::help --> get these infos
tclgif::info --> get info about gif stream
tclgif::colpal --> get gif color palette as rgb triple bytes
tclgif::coludf --> get udf color palette as rgb triple bytes
tclgif::colget index --> get r,g,b values of palette entry
tclgif::colimg image --> get image colors as list of rgb triple bytes
example tclgif_tcl.tcl
start wish
source tclgif.tcl --> create a simple gif animation as file matze.gif
todo:
- implement a canvas to image feature, so you can use a canvas as animation tool
- implement a widget to image feature (like as img::windows), so you can make a screenshot animation
TRY IT ;-)
I hope you have fun.
