Write Photoshop script to export timeline as a png sequence

Report · Feb 17, 2017

I wrote following script to export time line as png sequence i want to optimize the code.

Please advise

// enable double clicking from the Macintosh Finder or the Windows Explorer
#target photoshop
// in case we double clicked the file
app.bringToFront();

Are you sure that script listener code does what you claim. It looks like that script would try to open the first file in a folder that you select no matter what kind of file it may be. I do not see any loop you added to process frames in a timeline. The sequenced Make layers from frames follow by make frames from layers seem wrongs to me where did the Frame animation come from I see no create frame animation was the first file required to have a frame animation if so would it not already have the layers and frames. Why select a folder of files if you only process the first entry in the folder. I can not believe that is a working script.

Thanks for reply

script working fine for me!

I have created this script to change the animation frame rate and change the last two frames only.

It looks like that script would try to open the first file in a folder that you select no matter what kind of file it may be.

-- when user should select the destination folder is full of ".png" images only! (no other type of files will be there)

I do not see any loop you added to process frames in a timeline

-- Check the line number 21,22,23 code "( idsequence, true );" This code add all files and put on timeline so no need to write loop for this.
