Maximum file size 300 KB for each image. ZIP file is less than 20 MB.
  • (*2)The first image of the APNG will be displayed as a static image on LINE STORE and the LINE Sticker Shop.
  • Use Firefox to test out your APNG files.
    Until now you had to combine PNG images with an APNG creation tool such as APNG Assembler. Now you can generate APNG directly from animation by using 9VAe.

Let's make APNG !

In this article the barrelFish animation is used as an example which is created from Openclipart's SVG illustration. (SeeMake animation from Openclipart's SVG with Raspberry Pi )

If you want to try to make APNG, Click [help] on the 9VAe's menu > Click 'Play with face(Training)' > Click 'Transform'. Now you can get a sample animation.

The picture as follows shows the editor screen of 9VAe.

  1. Click [File] on the menu bar > Click 'Sequential images/APNG export'
  2. Enter the name of APNG file. Click [Save].

Now the APNG setting panel will appear as follows.
