Question

Dear all,

I have like hundreds of files. Each file has it's own "sister black&white file" which is ment to be used as a mask.

I was wondering if it is possible to automaticly merge those 2 files so we would end up with a masked image..png or whatever....

It would be a monster job to do it all by hand...

Maybe a a script or badge???

kind regards,

What are the naming-rules and the files’ locations (side by side?) and is the Alpha a grayscale image or RGB, too?

Edit: Could you post a pair of files for testing?

the alpha image will be rgb.

The filenaming is not problem - that we can take care of...

in other words - you can call it whatever you want...

thanx

Oh ic,

thanx, that is becauseI don't know how to do that....

This just an existing script I adapted...

How do I do that?


You could change the save options to something like: 

tifOpts = new TiffSaveOptions() ;      
tifOpts.embedColorProfile = true;      
tifOpts.imageCompression = TIFFEncoding.TIFFLZW;
tifOpts.alphaChannels = false;      
tifOpts.byteOrder = ByteOrder.MACOS;
tifOpts.layers = true;

And the export-line to 

var docName = doc.name;
var basename = docName.match(/(.*)\.[^\.]+$/)[1];
doc.saveAs((new File(ofolder + '/' + basename + '.tif')),tifOpts,true)
doc.close(SaveOptions.DONOTSAVECHANGES);

And if you think it would be easier if I just amended the Script, that might be so, but you may pick up more this way, I guess.
