NPrinting Chart Background Transparency

[Anonymous]

Hello,

I'm using NPrinting PixelPerfect reports to create JPGs of my QlikView charts. I'm dragging in an image of the charts to the PixelPerfect report template and using the output format of JPG in the task settings. In order to get one of my charts to work as intended in QlikView, I had to create one combo chart, then overlay a second combo chart with a transparent background. When I do this, it works perfectly in QlikView. However when I put both charts in the PixelPerfect report template and try running it, the second chart loses it's transparent background and the JPG file just comes through with a white background, covering up the first chart behind it. I checked the properties of the chart with the transparent background, and in the Appearance section, Background Color is set to Transparent. Is there another setting I need to change, or is this functionality not possible in NPrinting?

Thanks

Hi Andrew,

If you RMB on your chart in your QlikView document and then select Copy to Clipboard > Image (or Export and select an image type) and check the result, you will find that the background transparency is not retained. QlikView NPrinting uses the QlikView Desktop API to render the chart images so you get the same result.

PixelPerfect has a huge range of chart types available - perhaps you could build them there? If you do, you will have a lot more control over chart properties. For example this screenshot shows background transparency:

I'm not sure if building the charts directly in PixelPerfect will get me exactly what I need, but I understand why it won't work the way I'm trying. Thanks for your input!
