Images into Arrays

[DragonDigital]

I need to find a way of transfering a Picture (that the user will just have drawn) into a Array. I can't save the image

You mean, the user draws it on a picture bos?

In that case, you can try: Pictur1.Picture = Picture1.Image (maybe you need Set picture....), then you can save it with the VB function.

Sorry, didn't make myself clear. I need to transfer a picture to a array of bytes (which gets sent to a webpage). And I can't save the picture and reload it into the array.

[Crazy D]

That makes more sence.. Actually I don't know... Never had any need to do that.

Maybe you can use a memcopy?

What is the source of the picture? Is that a picturebox, or something else?

[DragonDigital]

The picture is generated at runtime in a PictureBox control. I can copy this to another PictureBox or save it, but... Since I don't know the address where it's stored, I can't do a CopyMemory.... Any ideas?

[Crazy D]

Can you use Picture.Picture as source for the copy?

On the other hand, if you can save the picture, you can try to read that bitmap out. It contains a few headerinfo structures (user defined types), and an array of bytes. Maybe that's an option. I haven't done that (no need to...), but it can't be that hard to do.

I should have said: I know how to save it, but I can't this time. So no Saving!

All the copy commands I have found, either take copy picture to picture or memory to memory.... I can't seem to go from Picture to memory directly.

[Crazy D]

Hmm.... I'm, not sure how to do it out of my head, but maybe you can create a compatible dc in memory, vopy the picture to that dc, and copy it from that dc into the byte-array (although, if this works, it should work when you try to copy the picture dc to the array, and I doubt that, but maybe it's worth a try).
