Our patron card design has a background image, which is the same size as the plastic card, (2" height * 3.25" width).If we prefer to locate the barcode at the front of the card, the barcode will be covered by the background image. Just wondering that ----Is there a way that we can bring the barcode to front of the background image? http://git.koha-community.org/gitweb/?p=koha.git;a=blob;f=patroncards/create-pdf.pl;h=6a1b67a57326883ccdb2d100efaf9834a7c6ce42;hb=HEAD#l134
For the image, there is a way to change the display height, just wondering is there a way to adjust the barcode size too?
What you are asking in the first command is related to adding z-index capabilities to Patron card creator. As Chris Cormack said on bug #8375 (comment 15), this could be done throwing away current code and using a CSS approach.
Using an image with a transparent area might help the issue. Not all graphic formats support transparency, so this might be something to check. Otherwise I am not sure if this is still valid. Barcode size should be on a separate bug.
For barcode size there is already bug 10762. I believe the graphics issue is solvable by using transparency. Please reopen if I am mistaken!
