It seems like it would be possible if the bitmap you currently generate has an invisible background. You could generate the grid and scroll as fast as necessary while a separate image in the background stays stationary.

I'm not sure if this is what you mean but i once made a program to put an image over my desktop. It worked by using a function that causes a chosen rgb value in the bmp to show up as transparent.


Is that what you mean? I ask because if that is possible without wasting resources then technically it should also be possible to have a stationary background and scrollable image frames\borders\mounts\backgrounds at the same time, allowing for a much more dynamic grid. e.g.

- these are just random images from Google, credit to whom credit is due

Yep, thank you for your help, but I already know how to draw a transparent bitmap (there are many icons in the program that have a transparent background).

My problems are elsewhere:

1) will the scrolling remain smooth when drawing with transparency ?

2) I don't know yet how to create an image with some transparent parts, how to reset a part of the image, etc... Shouldn't be too much of a problem, but I have to make some research on the subject.

I guess that means i kinda got what you were trying to explain then. Do I get a gold star?


That's what has me on the edge of my seat. That would make some really cool stuff possible.

Of course !



Yep, I think it's worth the extra work. And if a user has an antique computer, he'll just have to pick up a skin that is less demanding.

Thank you for making me reconsider.
