RadaeePDF viewer is showing a gray color border outside of PDF content (UWP)

Dear Support,
When PDF content is displayed using the RadaeePDF viewer, we can see the gray color border outside of PDF content.
We want to remove the border from LEFT, RIGHT and BOTTOM and only want to keep in the TOP.
Please refer the attached screenshots for more details.


Looking ahead for your quick response.

Thanks & Regards,
Alok Pandey

Dear Alok,

Are you using the vertical view mode?

In case of vertical mode, the default behavior is to fit to screen width, so as you can see in the screenshot, there is no gaps on the left and right sides.

And in case of dual/single view modes the page is centered so you may find gaps on left/right.

The back color (grey), can be changed using PDFView.vSetBackColor

Have you modified something to the default behavior?
