/*
|
||||
* vo_tga.c: targa output
|
||||
*
|
||||
* this video output module write targa uncompressed file in 15, 24 and 32 bit bgr format.
|
||||
*
|
||||
* to select the output format use the format filter:
|
||||
* mplayer -vo tga -vf format=bgr15 ...
|
||||
* mplayer -vo tga -vf format=bgr24 ...
|
||||
* mplayer -vo tga -vf format=bgr32 ...
|
||||
*
|
||||
* The 16 bit file are loaded without problem from Gimp and ImageMagick but give an error
|
||||
* with entice (a visualizer from the enlightenment package that use the imlib2 package).
|
||||
*
|
||||
* In 32 bit mode the alpha channel is set to 255 (0xff). I may not work with big endian
|
||||
* machine (is probably enought to change the TGA_ALPHA32 from 0xff000000 to 0x000000ff).
|
||||
*
|
||||
* I need to fill the alpha channel because entice consider that alpha channel (and displays
|
||||
* nothing, only the background!), but ImageMacick (the program display) or gimp doesn't
|
||||
* care.
|
||||
*
|
||||
* maybe is possible (with a compilation switch) to avoid the fill of the alpha channel
|
||||
* and work outside mplayer (if needed)
