However, if you make an image 9933x4961 (A1), the file is not saved
FW_SaveImage(hBmp, "myfile.png")->.F.

I think the problem is not saving large formats through the FW_SaveImage function.

To get a larger format, I expanded the dialog box to the desired size (oDld:Move()). Further, moving this dialog according to the specified algorithm, I received the device context of the screen. It used to work, now ...
