Wrong background color in BMP/PNG file

[rmkk]

Friends,

when I export diagram to BMP/PNG image, the background color is wrong - it differs to background color in EA screen. Screen shows dark background, BMP image shows light background.

Steps to reproduce

• Set Start / Appearance / Preferences / Diagram / Themes to Flatline - this will set default diagram background to light color
• Choose one diagram and open it, open Properties / Theme and changed the Theme to Dark, colors on this particular diagram changes to dark ones including background, very nice
• export this diagram using CTRL+C / CTRL+V or using Publish / Save / Save to file / BMP, PNG, ... - you will see the light background color, very ugly :-(

Thanks for help.
