Backimage with PrintPreview not transparent and to big

Post by Marcel Horsthuis » Thu Apr 20, 2023 10:06 am

Hello
I Have a graph with a company logo placed in the back image of the chart and on the screen it looks good.
When I use the Print Preview function the logo is not transparent anymore.
If I print the Preview then the logo gets very big and not transparent.

Please Help,

Marcel

Hello Marcel,

What code are you using to position the image? If it's done via code, the location and size need to be proportional to the chart dimensions, not absolute.

I'm not sure we can resolve the transparency, I'll test a couple of options.

Hello Marc,
I used the chart editing dialog to set the background.
See attachment.
Background can be solved by setting the background of the logo.

Hello MArc,

Solved in the latest version v2023.38.230607 of TChart.

Thank you

Marcel
