Combining two images into one

[toddgeist]

hello,

I have two images that I would like to combine into one by placing one on top of the other. I need to maintain the transparency. I can see how this might be done by writing out new imageData from the combination of two imageData containers. But does anyone have any examples?

Thanks

Hi Todd,

naive question, but can't you "physically" put these two images on top of each other
on a card and then import a screenshot from that area?

Sounds much simpler than dealing with IMAGEDATA

doesn't snapshot just do a screenshot of the area? if so, won't that be lower resolution?

Hi Todd,

doesn't snapshot just do a screenshot of the area?

Yes, what else?

If you group these two images and then import a snapshot from the rect of that group,
transparency will be preserved.

But hey, I am just guessing from your sparse infos

if so, won't that be lower resolution?

Well, a screenshot is a screenshot and has the resolution of the current monitor

And that is why I am questioning if there is a better way.

Does imageData contain different information that what you would get from a snapshot?

Am I loosing resolution by doing a snapshot?

These are the basic questions

Hi Todd,
Yes, snapshot uses the current screen resolution, which is good enough if nothing else happens to the image. But if after the image merge you want to zoom in or print out or some other manipulation then you want to work with the image data. If you don't do anything else with the image then snapshot is the easy way.

Thanks Simon, for verifying my concern with import snapshot. I do need to do other things with these images after I am done.

So now back to the original question Does anybody have any an examples that show how to merge two images using imageData?

Thanks

Have you looked at this:

No, it's not about combining 2 images but it gives you info on working with imageData.

I did see that lesson. It was helpful. I think I can figure this out. I was just hoping to not have to
