Two addenda: FIrst: Create any image. Use the paint tools to create a little black, but keep the paint tools away from the upper left corner. I find that the imagedata shows these pixels to be black. The imagedata function does not seem to represent images created with the paint tools. Se

Re: Starting at square one with image processing

There is a typo in the simplified version of the script most of you will already have noticed: Instead of "put (chartonum(char tij+ 2) of idata)) into tRed" add the missing bracket and use "put (chartonum(char (tij+ 2) of idata)) into tRed" or leave out the inner brackets "put (chartonum(

Re: Starting at square one with image processing

James, You are on the right track. Your interpretation of the pixels is correct. However, I would pay special attention to the size of your image - setting the imageData can reset scaling you have done, which off of the top of my head is probably why you are seeing a line become a square

Chipp has done some very good imagedata and alphadata example stacks. You should see how he does: ImageTrans.rev altMakeTrans.rev and Wilhelm Sanke tiles_seamless.rev Jim Ault Las Vegas On 7/6/07 4:51 PM, "James Hurley" <[EMAIL PROTECTED]> wrote: > I've discovered that I have no idea what's go

Re: Starting at square one with image processing

I've discovered that I have no idea what's going on with the imagedata function. I thought that the imagedata was a pixel by pixel map of the image. I tried the following handler to look at each pixel of my image: on mouseUp put the name of image id 1014 into tName put the imagedata of

Re: Starting at square one with image processing

Jim, imageData is a pixel-by-pixel property. Pixels are read in rows across and then down. Each pixel is 4 characters long: alpha, red, green, and blue. So for example, a white pixel would be 0,255,255,255 A black pixel would be 0,0,0,0 A red pixel: 0,255,0,0 A 50% transparent pixel: 127, re
