Hello wout, I have a large cad file, the graphic dimensions in cad is about 150mm. I want export this cad to image, and have a resolution about 4um per pixcel, so the target image size will be 37500*37500, but System.Drawing.Bitmap can not create so big image. So, Is there a solution? Thanks so much.

Hi, Max bitmap size is 2^31 bytes (2 GB), there's no way around that. - Wout
