NAME¶
apngasm - assemble individual PNG files int to animated PNG file.
SYNOPSIS¶
apng2gif <OUTPUT *.png> [<INPUT *.png>] [options]
DESCRIPTION¶
Assemble individual PNG files into animated PNG file.
Some optimizations used in APNG Assembler might re-sort the palette, or change
the color type from RGBA and RGB modes to RGB and indexed modes. Those
optimizations are only performed when they are lossless, but if you want to
avoid changing the palette or colortype, see options to turn them off.
The Animated Portable Network Graphics (APNG) file format is an extension to the
Portable Network Graphics (PNG) specification. It allows for animated PNG
files that work similarly to animated GIF files, while retaining backward
compatibility with non-animated PNG files and adding support for 8-bit
transparency and 24-bit images.
OPTIONS¶
- /kp
- Keep the original palette and do do not optimize for created APNG.
- /kc
- Keep the original color type.
EXAMPLES¶
[Example 1] With following files, to have 3/4 seconds delay between the frames:
frame01.png
frame02.png
frame03.png
apngasm output.png frame01.png 3 4
You can control individual frame by creating control files, like for
"frame02.txt":
delay=25/100
[Example 2] The same as above, but the with frame00.png, which is
"invisible". Notice the use of option
/f:
frame00.png - invisible
frame01.png
frame02.png
frame03.png
apngasm output.png frame00.png 3 4 /f
That way APNG supported browsers and image viewers will show
frame01-frame02-frame03 animation, while IE and Chrome will display static
frame00.png image.
[Example 3] This way you'll get 1/10 sec delay:
apngasm output.png frame01.png

None.
