| H A D | agg_renderer_region.h | diff d56beda4 Wed Jul 22 13:36:10 MDT 2015 Julian Harnath <julian.harnath@rwth-aachen.de> app_server: optional coordinate shifting in renderer_region * agg::renderer_region gets an extra feature which allows to optionally shift the coordinates by a specified offset. * This allows to shift coordinates at the lowest level, even below the transformations done by BAffineTransform (which happen in the painter, right before rasterization). Needed for layers support: shifts the origin of the layer bitmaps to their position in the view while keeping all transformations (BView origin/scale transforms as well as BAffineTransforms) intact. The offset for the layer bitmaps within their parent view is determined by the bounding box and is then fixed, it must not be altered while the layer's BPicture is played into the bitmap. If this offset were added to the BView origin or as translation in the BAffineTransform, it would be further transformed by the BView scale or the other affine transform parameters. Thus, we need another low-level offset mechanism which is even below BAffineTransform's transformations. |
