But when I save the bitmap and load it with another program *ON THE SAME MONITOR* it works. Thus the system is messing with it (probably scaling it on the x-axis) somewhere between the bitmap and the screen. I have a panel on the form, in the panel a picturebox and the image is put in the picturebox. This is because there is a minimum size the image must be in order to convey needed information, if I have more space available than that I try to fill it with optional information rather than let it go to waste. >A texture can repeats itself (wrap mode) to fill variable size area, rather >than being limited to enlarge its original 'pixels' to fit the area, and >will even fill convex area with matching the pattern (example, painting a >T, the texture in the steam is aligned with the texture in the flanges, >automatically... if you use the same brush to paint). See "Pro .Net 2.0 >Graphics Programming", by Eric White, at Apress, pp49+ I'll have a look, although all the texture work is done so I probably won't touch it.

[...] Sure. And that could be somewhere in your program, or somewhere later down the line. Until you post a concise-but-complete code example that reliably reproduces the problem, there's no way anyone here can tell you for sure whether it's your program that has a bug, or some configuration issue external to your own code.

There are two for any form created in visual studio. One (the .Designer.cs) should be pretty much nothing but properties you set in the form designer.

One more time: just look at the code example I posted for an example of "how it is going to work". You just need to put all the relevant stuff into a single file. It's as simple as that. Pete |
