Hi there,
Can someone tell me how to remove ( overcome) the pixels offset during drawing in GDI. I know the GDI+ has a PixelOffsetMode, but GDI seems not having. Any tips and ideas?

It is not clear what problem do you have with pixel offset; this matter is very delicate, especially its impact of both performance and quality, especially in zooming of images.

I advise to read this interesting and advanced CodeProject article: Image Resizing - outperform GDI+[^].

Yes, I know it's .NET but it can give you some ideas; it's generally very hard to find information in this topic.

The problem is this. I'm trying to draw a symbol (an airplane shown from above). Now normally the left and right side along the long axe should be the same....but they are not.
