2018-01-17Fix behavior of FPDF_RenderPageBitmapWithMatrixHenrique Nakashima
This functional part of this CL is mostly a revert of "Change behaviour of FPDF_RenderPageBitmapWithMatrix" 24b0733a72bbc4013bff8628f198b0aea807aa06 Besides the revert, the parameters passed to pPage->GetDisplayMatrix() are changed to fix a bug with the previous implementation: the page was scaled to fit inside the clipping_rect, instead of clipped.
