Chart.ToImage() - can it show transparency?

Aspose.Cells Product Family

We use Cells to create charts for PowerPoint presentations and use the ToImage() method to display a picture of the chart until it is activated. Problem is that although the chat area is set to transparent the generated image has a white chart area which doesn't look great if the slide has a color background. Any chance that the image can honor a transparent chart area?

Thanks.

Hi Amjad,

Thank you for your quick response! Unfortunately I still get the same result as before, the chart area remains white.

Thanks again.

Addendum to my above comment - it does work for PNG image format. I usually use the EMF as that scales nicely for various chart sizes. Do you know if EMF supports transparency?

Thank you.
