I would like to have the background of the form unifom in colour with my logo in the header, this will not be possible however if i can not add a transparent logo into the headr. Is it possible?
It is possible. There are a lot of types of images and transparency and most should work in our forms, but some may not and if we have access to an image that doesn't work we may be able to fix it so that it does. I just tried a handful that worked great, both in the HTML form and the PDF. Would you mind sharing your image with me at firstname.lastname@example.org and I will take a look at that specific image?
