* lcd/grey: Enable viewport fg_pattern and bg_pattern for all bitmap targets.Thomas Martitz2014-01-07
| | | | | | | | | Greylib performed a horrible hack and stored fg and bg patterns in other struct viewport fields. One of them was just removed. So instead of this hack simply enable the *_pattern fields for mono targets as well, so that greylib can use them normally. Change-Id: Ib0842ebcc97f5bf9d9382b4471903afa2f96f39f
* Adapt OSD in plugin lib to be greylib compatible.Michael Sevakis2012-12-18
| | | | | | | | | | | | | | | Requires addition of viewports and alternate framebuffers to greylib which are essentially similar to the core implementation except that the framebuffer can be any size and relationship to a viewport. Drawing is always fully clipped to the intersecting area. Adapt oscilloscope.c to the API change. FFT will use the new features (later update). Get rid of silly and wrong lcd_bmp_part use in OSD. Remove it from plugin API (must be made incompatible now). Change-Id: Iafa5e2174148fb8ad11db6b9d4add0dcabc5c563
* Speed up mono bitmap drawing on horizontally packed greyscale targets ↵Jens Arnold2009-06-01
| | | | | | (greyscale iPods). Average speedup is 80% on PP5002, and 55% on PP502x. * Simplify mono bitmap drawing in the 16 bit driver and the greylib a bit, also giving a slight speedup (3% on PP502x, 1.5% on coldfire). git-svn-id: svn://svn.rockbox.org/rockbox/trunk@21163 a1c6a512-1295-4272-9138-f99709370657

| | | | | | | | ARM and Coldfire, at the cost of an extra add/shift in the horizontal scaler to reduce values to a workable range. SH-1 retains the same basic math, as the use of 16x16->32 hardware multiplication in the earlier scaler stages saves more than removing the 32x32->40 multiply to descale output. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@21091 a1c6a512-1295-4272-9138-f99709370657

* Greyscale library: Changed the internal data format once more (separated ↵Jens Arnold2008-01-09

Previous version was too slow to keep up at 45MHz, leading to unwanted graininess (update frequency was halved). Also fixed screendump on 2bpp targets with vertical pixel packing. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@16043 a1c6a512-1295-4272-9138-f99709370657
* All-new greyscale library, replacing the old one. Features: (1) ↵Jens Arnold2008-01-04
Drawing/updating is faster than the old grayscale lib at full depth. (2) Always 129 shades instead of 2..33 shades. (3) No graininess caused by frequent updates (mpegplayer, doom, ...). (4) Needs less memory than the old grayscale lib at full depth. * The tradeoff is slightly higher CPU load in the ISR (frames are calculated 'live') and an extra function in the core. * Ported all plugins which used the graylib to use the new one. * Some slight optimisations for archos and H1x0 LCD update. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@15998 a1c6a512-1295-4272-9138-f99709370657
