2013-09-27Improve performance of copyArea(), especially relevant for mobile devices.tsahi glik1-21/+66
vigra::copyImage89 does not handle copy areas in the same image so the code checks whether the src and dst are same buffer and directs it to scaleImage() which is very slow. The whole concept of pixel accessors is a huge overhead in the case of direct pixel copy (vigra::copyImage is also using pixel accessors). The idea here is to identify when direct memory copy is applicable (when the format is an integral number of bytes per pixel, src.size==dst.size, and src.format==dst.format) and use direct memory block copy and not pixel-wise copy. The result is 100x faster than the vigra implementation. This direct copy is also handling the case when the src and dst are same buffer by copy it from bottom to top when needed and using memmove() instead of memcpy().

2013-04-12Nah, I don't need a getOffset(), but I do need a getBufferSize()Tor Lillqvist1-21/+34
To properly handle subsetted BitmapDevices in the iOS vcl backend I seem to need to know what the size of the full BitmapDevice is. I wasted at least one day on desperate hacking and debugging, trying to wrap my head around a misunderstanding of what a subsetted BitmapDevice is. I thought it involved coordinate offsetting...

2011-11-04Put BitmapDevice::getPixelData() back.Thorsten Behrens1-0/+16
Slight tweak of d0d62edf3f398e9ddb2fd0f1f5fbe1dd0393ff47 - getPixel() and getPixelData() are complementary functions, similar in spirit to const and non-const getters. Added unit test for it to avoid flagging it for removal again.
2011-11-03Cleanup basebmp a littleJoseph Powers1-21/+0
I removed 2 unused headers. I also stopped delivering a lot of headers that no one outside of basebmp cared about. I also removed the unused methods: basebmp::BitmapDevice::getPaletteEntryCount() const basebmp::BitmapDevice::getPixelData(basegfx::B2IPoint const&)
2011-11-03Fix one more subtlety around B2IBox / B2IRange changes.Thorsten Behrens1-23/+12
The Cohen/Sutherland clip flag routine was not aware of B2IBox, thusly yielding incorrect line clipping for BitmapDevice software rendering. Cleaned that up, added some more unit tests around the problem, and removed the now-extraneous maLineClip member from the bitmap device.
2011-11-02Move BitmapDevice to use B2IBox instead of B2IRange.Thorsten Behrens1-115/+110
Semantically, B2IBox represents a pixel rect much better than B2IRange - replaced all occurences in and around the software renderer, and client code.
2011-11-02Keep basebmp free of naked ptrs.Thorsten Behrens1-68/+76
Moved the implementation detail that SalFrames lifetime is handled manually in vcl out of basebmp & into vcl. Added lightweight wrapper class to decouple damagetracker lifetime from GtkFrame lifetime.
