Make transparent areas white converting from png to jpg

[doobox]

Hi there,

I set about converting an image, from a png that contains transparency around the outer edges, to a jpg file saved to disk.

So great i can simply do this and i am 99% there :

Code: Select all

on mouseUp
   // image "mail" below contains a png with transparency
   export image "mail" to myImageContent as JPEG
   put specialfolderpath("desktop") & "/miniVersion.jpg" into tOutputPath
   put myImageContent into URL("binfile:" & tOutputPath)
end mouseUp

Trouble is, i don't seem to have any control over the background color of the output jpg file.
It always makes the transparent areas black... I would like white.
Is this possible to control..?

Hi Gary,

you can:
1. deal with imagedata and maskdata (way over my head ) or
2. put your image in front of a white graphic (same size as image) and export a snapshot of that rect.
