Created attachment 22460 [details] A PDF file using the extend property (badly rendered) The problem comes from linear gradient rendering. In one file I did generate (this maybe the reason why the bug does appear there and not in many other places), I use a linear gradient from one colour to another. Only acrobat seems to fill the part of the gradient that is not (indeed) the gradient with the determined colors, as should be when the Extend values are set to true. The reference page is page 186 of the PDF 1.7 reference manual. Quoting from this reference: "An array of two boolean values specifying whether to extend the shading beyond the starting and ending points of the axis, respectively. Default value: [ false false ]."
No we are not ignoring them, just not treating them in a totally correct way, i've a patch that fixes this particular pdf but i'm not totally sure it's correct so you'll have to wait until i run it over the regression tests here. The problem is that i don't have any regression tests, so i have to code that first. Might take a while, hopefully less than a month.
Fixed, will be in next poppler release
