Thanks for the kudos, Mark! Yeah, I discovered that that bytes are switched between Mac and Windows; glad you got some use out of it...   Ken Ray Sons of Thunder Software Email: [EMAIL PROTECTED] Web Site: http://www.sonsothunder.com/   ----- Original Message ----- From: Mark Luetzelschwab To: [EMAIL PROTECTED] Sent: Friday, July 05, 2002 10:52 AM Subject: Re: Fun With ImageData, MaskData and AlphaData Ken, Thanks for sharing these functions about imageData, etc....they were always in the arena of "when I might have some time"...but now they are quite within my grasp! Two items: 1. The order that you had in your example for making the 50% transparent blue image: repeat with i = 1 to 400     put binaryEncode("CCCC",255,0,0,0) after iData     put binaryEncode("C",128) after aData   end repeat did not work for me on my Mac, using 2.3.2 I had to switch the order: repeat with i = 1 to 400     put binaryEncode("CCCC",0,0,0,255) after iData     put binaryEncode("C",128) after aData   end repeat 2. Just for fun - I added a red-to-blue gradient..you can add to your page if you so desire! (this is for a 16 x 16 image - will require some more calculations for other images) repeat with i = 1 to 256     put binaryEncode("CCCC",0,min(i,255),0,max(255,255-i)) after iData     put binaryEncode("C",128) after aData   end repeat Thanks again - your work is most appreciated! -ml -- Mark J.
