Newcomers DBPro Corner / Can you paste images over each other and sort of AND them...?

For example, if I paste one image over the top of another, if any of the pixels of the original image are brighter than the one going on top, I don't want them replaced by the darker pixels.

I suspect there's no way of doing this other than purpose written code to check images on a pixel basis, but I thought I'd just check first of all that there isn't some nice command in DBPro that will achieve this.

I've looked and can't see anything obvious...

You could put out the images one at a time on the screen, and then check the color valur of every pixel in the image and store the resolts in an array. Then you could check which pixel (of course only the ones on top of each other) that is brighter using the "point" command and then draw out the brightest pixel using the "dot" command, or something like that. I've not tested the code and I don't know if it would work. But I hope it works.

That's exactly what I will have to due if there isn't some clever command/function to in effect automatically achieve this...

NeilF,

Do not use the point command! Use memblocks instead. The point command is slow and useless, and will bring down your fps drasticaly.

The best way is to use memblocks.
Convert the image to a memblock then perform a logical AND on each pixel before making an image from the memblock.
