vb.org Archive - Photoshop Script to Change Matte Color

I created a Photoshop script that will open all the PSDs in a folder and Save To Web as .gif using a matte color you specify in hex out to a folder of your choice.

You need to specify the hex color in the code around line 52, just put in the value without the preceding "#" sign. Copy and paste the code to into a new text document and save it as <somename>.jsx .

Unfortunately, it doesn't do folder traversing so if you have multiple folders it will be necessary to do each folder individually. I created this script especially for use with the vBulletin PSDs for easy matting. It has been tested in Adobe Photoshop CS2.

Code below... let me know how you like it.

// enable double clicking from the Macintosh Finder or the Windows Explorer
