Possible issue with TeecreateMetafile

Hello,
I thing there maybe an issue with TeeCreateMetafile when display scaling is enabled. The attached metafile was created with screen resolution set to 3200x1800 and scaling 150%. Anyone else noticed that behavior? (TeeCreateBitmap works ok)
Regards

Attached is the sample code I used to create the wmf and bmp. When setting the resolution to a high one and scaling is larger than 100% then the wmf is not exported correctly

Ok, it looks like that I cannot make the app create the "correct" size metafile unless I have the Enable High-DPI checked in the Project->Option->Application section. I was looking for a solution for the metafile issue when the High-DPI is unchecked ... maybe there is a work around?

None that I know (other than using a custom manifest with "dpiAware" set to true)

Hello Yeray,
There is a work around, you need to set the metafile MMWidth and MMHeight properties, I modified the TeeCreateMetafile to do so (resulting metafile looks great) but there is an issue on how to get the custom system scaling value (remember I need not to enable the dpi-aware feature).
