Compiling gif2apng on debian

[SplitIce]

Came accross something I thought to be pretty unique today, the ability to animate PNG's. First of all I will warn that this requires Firefox 3 or Opera 9.5 or a couple other browsers may support it (Not IE).

What is an animated PNG?

^ IF you cant see that moving (once it loads of course) then your browser doesnt support animated PNG's

How do I make one?
Many ways although gif2apng is the best way on linux (console), and so I will guide you through compiling it.

When/Why should I use animated PNG's
- To save bandwidth, you can save 20% easy, even more will be possible once firefox fixes support for BLENDING (40-50%)
- Backwards compatible with PNG, people who dont support APNG should just see the first frame.

Install dependencies:

apt-get install zlib1g-dev zlib1g

# cd ~
# mkdir gif2apng
# cd gif2apng
# wget http://downloads.sourceforge.net/project/gif2apng/1.1/gif2apng-1.1-src.zip?use_mirror=transact
# unzip gif2apng-1.1-src.zip
# rm *.zip
# gcc -Wall -lz gif2apng.c -ogif2apng

There you go its compiled, you may want to move the executable into the local path with a comand like:

mv gif2apng /usr/bin

then just use it like:

gif2apng in.gif out.png

Thanks man !

Yeah howeaver you will need to alter the apt-get lines

You can also compile these APNG projects the same way:

http://sourceforge.net/projects/apngasm/
http://sourceforge.net/projects/apngdis/

gcc -O2 -o apngasm apngasm.c -lz -lpng
gcc -O2 -o apngdis apngdis.c -lz

I myself havent got round to doing what I intended with this, although what is the advantages of gif2apng compared to apngasm?

[maxst]

If your source is animated gif, use gif2apng.

If your source is PNG image sequence, use apngasm.

apngdis does the opposite: apng -> png sequence.

ah interesting. Definately going to fiddle with this in the future.

[litewarez]

is there any php libaries available or GD extensions to supoort this ?
