Say I have a Diagram that is 1920x1080. I call ExportToImage with an enclosingBounds of (0, 0, 1920, 1080), a returnImageSize of (1920,1080), and a dpi of 384.
I get an image that is 7680 x 4320. Is that expected? I am (perhaps naively) expecting to get an image that is 1920x1080, based on the value of the returnImageSize parameter.
Thanks!

Hello ,
The size of the Image that will be generated is based on two factors the ReturnImageSize and the DPI. If you are using the default DPI of 96 the Image will be saved in the format just like you expect. However once you change the DPI you are trying to save the image in bigger details. We internally scale the retrunImageSize based on a DPI factor (dpiScale = dpi / 96.0) and there for the image size is changed in order to save the image in the desired quality.
I hope this information helps.
Kind regards,
