Question

How do I script a PNG24 file to have white opaque background

I have a script that will export layers to png files but I want each layer to have a white background and not a transparent background

I am using these sets of export options.

var exportOptions = new ExportOptionsPNG24();

exportOptions.antiAliasing = true;

exportOptions.matte = true;

exportOptions.matteColor = RGBColorobject;

exportOptions.transparency = false;

I know I am using the exportOptions.matteColor = RGBColorobject; incorrectly but need some direction on how to get this to work.

even when I delete that line and have the transparency set to false and the matte = true I still get a transparent background.
Any coaching will be appreciated.

Delete the matte color line and try setting artBoardClipping to true.

Thanks for responding Larry,

I did that and when I open the png file in photoshop it still has a transparent background.

usually transparent backgrounds would be great but I need to isolate some patterns to be used on a 3D model in PS CS4

All the references I see say to just mark transparency as false…

Thanks!

I tried it and it still does not generate a white background.

I am going to post the illustrator file and the photoshop png result in another post.

I have to be doing something incredibly stupid wrong with the color space and am too bleary-eyed to see it


Give this a try? I think what is need to to set 'transparency = false' before matte = true; this works in CS2

#target illustrator

var userHome = Folder("~").fsName.toString();

var fileRef = new File (userHome + '/Desktop/Marks_Star.png');

docRef = activeDocument;

exportAsPNG24File(fileRef, 'Flat');

function exportAsPNG24File(saveFile, x) {

var exportType = ExportType.PNG24;

var png24Options = new ExportOptionsPNG24();

with (png24Options) {

switch(x) {

case 'Flat' :

transparency = false;

var bgMatte = new RGBColor();

bgMatte.red = 255; bgMatte.green = 255; bgMatte.blue = 255;

matte = true;

matteColor = bgMatte; break;

case 'Tran' :

matte = false;

transparency = true; break;

}

antiAliasing = true;

artBoardClipping = true;

horizontalScale = 100;

saveAsHTML = false;

verticalScale = 100;

}

docRef.exportFile(saveFile, exportType, png24Options);

}
