* put_line/scrolling: Make the scroll engine inform custom scrollers about ↵Thomas Martitz2014-01-12
| | | | | | | | | | | | | | | | | | | | | start/stop of scrolling. With the new lcd_putsxy_scroll_func() code can register custom scroll functions (put_line() makes use of that). In order for the custom scroller to be able to properly manage its userdata pointer (set via struct scrollinfo::userdata) the scroll engine must inform the scroller about start and stop of scrolling. To inform about start the lcd_scroll_* functions now return true when the line will scroll. To inform about stop the scroll engine calls into the scroller one last time, with the text set to NULL. put_line() can use this to release the userdata registered per scrolling line so that it can be recycled. This fixes that some scrolling lines became glitchy after some time because the userdata was recycled too early. Change-Id: Iff0a6ce2a4f9ae2bada1b8e62f4f5950224942a9
* scroll engine: Factor out renderer function so it can be called by lcd code.Thomas Martitz2014-01-11
| | | | | | | | | | | This is used by lcd_puts_scroll_worker() to render the line immediately instead of waiting for the next scroll tick when only the text was updated. Previously lcd_puts_scroll_worker() did not render anything in this case which could lead to visible blinking. This fixes blinking scrolling lines with dynamic text in the skin engine.

* lcd_nine_segment_bmp: Fixes for non-ideal image dimensions.Thomas Martitz2014-01-09
| | | | | | | | | | | 1) The 9-segment images need not be multiple of 3 pixels anymore. If it isn't the inner segments will be smaller than the corners. 2) If the desired actual images is not a multiple of the segment sizes the function drawed more than the desired rectangle. This is fixed by drawing the last segment only partially. Change-Id: Ic918facd8734fa4a4aa72536f0b67de82d81651e

* lcd-common: Remove direct style (line decorations) from lcd-puts* functions.Thomas Martitz2014-01-07
| | | | | | | | | | This logic is moved into apps (put_line()) which can better handle line decorations with respect to scrolling, mulitline and other complications. Firmware doesn't need this. The remaining drawing function know only one style, that is foreground on background/backdrop (changing drawmode is still supported). Change-Id: I707060edc388a7d723a7d09b0cf5cbda6ec56708
* lcd-common: Remove support for specifying y_offset from lcd_puts* functions.Thomas Martitz2014-01-07
| | | | | | | | This main (and only) purpose for it was to adjust the pixel position of the text in otherwise linebased (scrolling) functions. With pixel-based scrolling this isnt necessary anymore. Change-Id: I2a45b8ca6a3f8f50aa2f6630201b30ce9ddfe043
* lcd-common: Remove support for custom line heights from viewport.Thomas Martitz2014-01-07
| | | | | | | | Since scrolling is now pixel-based this is not necessary anymore. custom line height is handled by put_line() but can also possible to implement with lcd_puts_scroll_func(). Change-Id: Iee9b12bf99afac93d95d2a1a6f5d5b4db237b21c
* lcd-common/scroll_engine: Remove unused functions lcd_puts_style_xyoffset() ↵Thomas Martitz2014-01-07
| | | | | | | | | | | | | and lcd_puts_scroll_style_xyoffset(). With this functions removed there is no exported function in firmware left that draws line decorations. Also no function supports specifying an y-offset anymore (was used for pixel accurate positioning of otherwise strictly line-based API calls). Both should be handled in apps/ now.

* lcd-16bit: Introduce lcd_gradient_fillrect_part().Thomas Martitz2014-01-07
| | | | | | | | It is similar to lcd_gradient_fillrect(), except that it only draws a part of the complete gradient. This can be used to draw only the bottom half of a full gradient. Change-Id: Ib47cc5237f6966e35ba07988bddbb00fd97adf96
* lcd-common/scroll_engine: Introduce lcd_putsxy_scroll_func().Thomas Martitz2014-01-07
| | | | | | | | | | | This function supports installing a custom scroll callback. This will be called when the scrollengine redraws the line. It allows to draw extended styles (or anything your can possible imagine) along with the text. It is also strictly pixel-based, the first pixel-based function that supports scrolling.

* scroll_engine: Major rework to support pixel-based scrolling and scroll ↵Thomas Martitz2013-12-14
| | | | | | | | | | | | | | | | | | | callbacks. Much of the scrolling work is moved from lcd-bitmap-common to lcd-scroll.c, a small scroll callback routine remains. This callback can potentially be overridden by more extensive scrollers. The callback also gets fed with pixel-based scrolling information, which finally removes the strict line-based nature of the scroll engine. Along with this is the change from scroll_stop_viewport_line() to scroll_stop_viewport_rect() which works on a pixel-based rectangle instead of lines. The ultimate goal is to move most of the scroll work to apps, which can much better decide which line decorations to apply etc. This work is laying the ground work.

* lcd drivers: split lcd_gradient_rect so it is actually usefulJonathan Gordon2012-03-01

* lcd/skin_engine: Add the ability to draw onto the backdrop layerJonathan Gordon2012-02-28
| | | | | | | | | | | | | | The framebuffer the lcd driver uses can now be changed on the fly which means that regular lcd_* drawing functions can draw onto the "backdrop" buffer. The skin engine can use this to create layered effects. Add the tag %VB to a viewport to draw that viewport onto the backdrop layer. If you want to draw an image onto the backdrop framebuffer use %x(backdrop filename) instead of %X() inside a viewport with %VB. Change-Id: I741498e2af6d4f2d78932cabe8942317893e7cfc

* Anti-Aliased Fonts support.Thomas Martitz2011-03-05
| | | | | | | | | | | | | This enables Rockbox to render anti-aliased fonts using an alpha blending method. The input font bitmaps are 4bit, i.e. 4x larger, but the metadata size stays the same. A tool, convttf, for converting ttf fonts directly to the Rockbox fnt format is provided. It has a useful help output, but the parameter that works best is -c1 or -c2 (2 for larger font sizes).
