How Would I open Files in GraphicConverter using Applescript?

Thanks alot guys. I got it!!!!

Well that's my initial step for what i want to do.

What i want to do with graphic converter is i want to make an Applescript droplet into which the user drags a bunch of PNG files with a white NONTRANSPARENT Bground , and want my droplet

to make all thoes file's background color be transparent ...then save all those files with transparency.

So right now i don't have a clue how to do it but my algorith would be something like:

UPON RECEIVING A BUNCH OF DROPPED files

for all those files

-open the file

-Set the color WHITE to be transparent

-save the file

-close the file

end for loop

So i have other questions

1. My initial step: How would i let the script detect that a bunch of files are dropped into it?

2. My second step: How would i put all the received files into an array so i can manipulate them

3. What is the Graphic Converter command i would use to set the transparent Color of the image file that is currently being processed by the FOR loop?

I looked in the dictionary of Graphic Converter X and there is a command TRANSPARENT COLOR( RGB)

I searched for an example of using that, and i found one in the web

They use this:

tell application "GraphicConverter"

open theImage //This theImage was created somewhere in the file

tell window 1

//a bunch of other stuff which i will not write here

set transparency to true

set transparent color to {65535, 65535, 65535}

end tell

end tell

****

So i can kinda see how to set transparency but i thought RGB would be numbers from 0 to 255

so for example white would be 255 255 255.. But here it's 65535?

And would that be all it takes to turn the image's bground color( white) into transparent?

Thanks

Ok guys here's my first exercise for what i want to do.

But the transparency thing doesn't work. The open file does work!!! Thanks alot!

tell application "GraphicConverter"

activate

open alias "Macintosh HD:Users:myuser:Desktop:untitled folder:a.png"

tell window 1

set transparency to true

set transparent color to {65535, 65535, 65535}

end tell

end tell

While it doesn't give an error.. the BGround color doesn't get changed to CHECKER pattern. In GC, transparency is usually seen as Checkerboard pattern.

And usually to get that in the BGcolor of an image you have to use the transparency tool and click on the background (which is a solid color)

Guys i'm back and the transparency thing via applescript may not work cause the Graphic converter i'm using is Graphic converter X and i read in a site that has GC applescript examples and which was written in 2005, that

"GraphicConverter 5.6.3 (or higher, most likely) is the version of GraphicConverter that supports setting up transparency in an image via AppleScript. I wrote Lemkesoft’s support asking if it was possible to set transparency via AppleScript; they replied with a new beta version of GraphicConverter with this feature added."

So that was long time ago. The makers of GC probably didn't or haven't made transparency control via Applescript in this new version(version X). Maybe i should try my script using Graphic converter 5.6.3.

Just in case any of you are following . I just want to say i finally got it to work using Graphic Converter . ANd yup, you can't set transparency in GConverter X. I download version 5.9.5 and it works

tell application id "com.lemkesoft.graphicconverter"

activate

open alias "Macintosh HD:Users:myusername:Desktop:untitled folder:a.png"

tell window 1

set alpha channel to false

minimize color table

set transparency to true

set transparent color to {65535, 65535, 65535}

end tell

end tell
