Hello-

I need to create a graph with a transparent background. The graph will be inserted into a compound document to be output to PowerPoint and the background from the PowerPoint template needs to show through. The following post indicates this is possible by inserting two lines of code.

https://techsupport.informatio...om/sps/60762508.html

The code referenced in the case linked above is:

setFillColor(getFrame(),new Color(255,255,255,0));
setFillColor(getChartBackground(),new Color(255,255,255,0));

When I make that change and include in PowerPoint, the background is black and not transparent. Following is sample code from CAR.

Thanks in advance for any guidance.

AFAIK, only .gif have transparency possibilities. its puzzling to me why the techsupport article cites what appears to be a CMYK spec, new Color(255,255,255,0));
which would be black, wouldn't it?

PNG files can have transparency. Just taking the result to a HOLD file and opening in an image editor the transparency is there.

Could it be a PPT limitation?

ah. interesting.

Thanks for the responses. Based on Alan's comment, I output the file to PNG and then manually brought it into a PowerPoint and the background is transparent. The process of including in a compound which is then output to PowerPoint is losing the transparency. Any thoughts for a workaround there?

Pure guesswork, but could the technique here work, adding the graph as a watermark image.

how about just making the background color of your graf match the color of the .ppt? totally cheating, but might work for your customer.

From what I read, watermark is limited to one per and I will be adding many graphs to my compound.

I went back to the idea that the graph image that is saved is transparent when brought into a paint program (or PowerPoint for that matter). Instead of inserting the graph fex into the compound, I inserted it as an image using the gif file saved from the graph procedure and then used PowerPoint as the output type for the compound.

The graph still comes over with a solid white background but within PowerPoint I can choose Format Picture > Fill > No Fill and the white background goes away.

Unfortunately, the background in the PowerPoint is a gradient so it may be difficult to match.

oh rats.

Hi Barb,

Thank you for opening a case for this issue. Please keep us updated on the outcome.
