where is getFillColor?

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

I need to find out the current background color of a pdf document. There is a setFillColor function, but I can't find the setter. Is there such a thing or the white color is assumed to be the default background color unless changed? 
Thanks

	Hi Toran! There isn't a get available. Render the page to a thumbnail-jpg and then check few pixels near the frame - so you can get the color. Not a save method ;-) Cheers, Ingo

	Thanks, Ingo! Interesting approach. :) Do you think that missing getter is because of Pdf specs ?

	Hi Toran, that's no question of PDF-specifications. What you call the PDF-background does not exists as an single, well defined object. What is the background (and his color), if you fill it as half with any color and on the other half with an image? So it can give only the answer for the question: which color has a pixel at position x,y? And inside this question is a parameter, the size (scale) used for rendering. So what Ingo said is the only possible (but very unsure) approach. The problem is the question, not the answer. Cheers, Werner
