Performance Trend Report - Export to PDF: company logo distorted


I'm beginning to experiment with the performance trend reports available in the HP Performance Center tool.  I am using HP Performance Center 12.20, Build 12.20.628.0.  There's an "Export to PDF" option which allows your to add your company logo to the PDF report.  However, whenever I try this, the logo comes out squeezed vertically and does not look right.  I have tried resizing the image file itself thinking that there is a "window" that the PDF tool is using, but the image is always squeezed the same amount.  I have tried resizing my image to 75%, 50% and 25% of original all while maintaining proportions.

Does anyone have any thoughts on how to get the logo on the PDF report without it being distorted?
