I have code to capture windows/controls to a bitmap.

I am wondering if there is a way to capture the entire DataWindow, not just the part currently visible. It has been said since the early days that the DataWindow is displayed as a bitmap with editable controls superimposed. I want to know how to get the internal bitmap handle. If the bitmap only contains the visible portion, getting the internal handle wouldn't help.

TextSize does not apply to the main menu bar

Hi Roland;

   That functionality is not supported currently that I know of. However, the technique that I haved before for this is to use an intermediate medium like a PDF. Then once the PDF is rendered, you could use ImageMagicK (or GraphicsMagick - both free & open source) to then render the PDF in an image format. I have done this before very successfully. Food for thought.

FYI:  https://legacy.imagemagick.org/discourse-server/viewtopic.php?t=18193

HTH

Regards ... Chris

That would probably work. I tried saving as EMF! or WMF! but the fonts used are wrong and the EMF is unreadable.

If there were a SaveAsType for PNG, JPG, or BMP then it would be simple.
