* lcd-24bit: Introduce a 24-bit mid-level LCD driverThomas Martitz2014-06-21
| | | | | | | | | | | | | | | | | With LCD driver all calculation will be performed on RGB888 and the hardware/OS can display from our 24bit framebuffer. It is not yet as performance optimized as the existing drivers but should be good enough.The vast number of small changes is due to the fact that fb_data can be a struct type now, while most of the code expected a scalar type. lcd-as-memframe ASM code does not work with 24bit currently so the with 24bit it enforces the generic C code. All plugins are ported over. Except for rockpaint. It uses so much memory that it wouldnt fit into the 512k plugin buffer anymore (patches welcome).

* Touchscreen: Show a line separator in lists.Thomas Martitz2014-03-03
| | | | | | | | | | | | This patch adds a configurable line separator between list items, very similar to lists in Android. Additionally, below the list item there is a thicker line. It can be disabled in the settings. Its color can be configured as well. Remote and monochrome displays are explicitly unsupported. If there is desire this can be changed but it doesn't seem useful to me. Change-Id: I005313b0d8f5ecd15864bf20e66ea4e3390d8b7d
* Implement lcd_get_dpi() for all bitmap targets.Thomas Martitz2014-03-03
| | | | | | | DPI values are autogenerated from the resolution and collected display size values. These values are inserted as comments as well. Change-Id: Id03aedf9af18348f773dfce002805e480f6751e8
* 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

* 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
* lcd-16bit: Remove {lss,lse,lst}_pattern fields from struct viewport.Thomas Martitz2014-01-07
| | | | | | | These where used for line styling during scrolling, which is now done in apps/, The viewport struct doesn't need to record these anymore. Change-Id: I810d9dcb2644b00a798c6e75acab69c74a78e77f
* 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 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. Change-Id: I57f81ac7b3d08b877aea4cb8afa882f175ebcdfc
* lcd: Fix certain drawmode combinations.Thomas Martitz2014-01-05
| | | | | | | | Some seldomly used drawmode combinations did not work in conjunction with alpha bitmaps and backdrops. Now all should work (see comment added) by using more bits. Change-Id: I2bc96ecf471fa8c1a608a321a235b9c8527b3dc5

* scroll_engine: Add STYLE_NONE to allow for drawing lines without styling.Thomas Martitz2013-12-14
| | | | | | | This allows to draw lines without destroying styles that were drawn manually (e.g. from apps/) beforehand. Change-Id: I0de290c9343061efb115e1b76da5b76395c2b2af

* 9 segment bitmap drawing:Jonathan Gordon2012-12-09
| | | | | | | | | | Use %x9(id) to draw an image in the whole current viewport using the 9 segment drawer (which draws the corners as normal and *tiles* the middle segments to the needed width/height). Future work is to make it scale instead of tile Change-Id: Ic3ed1cad93f96091694801eb442e0da5a2401203
* lcd drivers: split lcd_gradient_rect so it is actually usefulJonathan Gordon2012-03-01
| | | | | | | lcd_gradient_rect() was only usable to draw list lines, so split it up and make a generic gradient draw function available to apps/ Change-Id: I665911a90fef239b5e06592ea2763cbeeb74c83f
* 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
* lcd drivers: Convert lcd_[remote_]framebuffer to a pointerJonathan Gordon2012-02-28
| | | | | | | | | | Change all lcd drivers to using a pointer to the static framebuffer instead of directly accessing the static array. This will let us later do fun things like dynamic framebuffer sizes (RaaA) or ability to use different buffers for different layers (dynamic skin backdrops!)

The chroma_buf scheme on Sansa Connect and Creative ZVx calling the lcd_write_yuv420_lines implementation in lcd-as-memframe.S with five params with a chroma buffer that the function can't use wouldn't work anyway so just have them use the stock implementation (really, how was that working?). git-svn-id: svn://svn.rockbox.org/rockbox/trunk@31335 a1c6a512-1295-4272-9138-f99709370657

* Support for transparency in 32bit bitmaps on color targets.Thomas Martitz2011-11-08
| | | | | | | | | This uses the alpha blending capabilities introduced with anti-aliased fonts to draw bitmaps with transparency information. The bmp loader is extended to read this information (pass FORMAT_TRANSPARENT in format). The alpha information will be used when drawing the bitmap. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@30937 a1c6a512-1295-4272-9138-f99709370657

It's configurable: * Automatic (default, line height calculated using a lcd dpi aware function) * Off (status quo, line height = font height) * X pixels (from 2 to 50 in even steps) The automatic setting should/aims to Just Work Out Of The Box on all targets git-svn-id: svn://svn.rockbox.org/rockbox/trunk@30773 a1c6a512-1295-4272-9138-f99709370657
* Touchscreen: Improved scroll thresholdThomas Martitz2010-11-10
| | | | | | | | | Remove the hardcoded (and way too small) scroll threshold (the distance moved in pixels before we think the users wants to scroll) and replace it with something based on the actual DPI of the screen. On Android we call the API for that, on other touchscreens we reimplemented Android's formula (as of 2.2) and calculate it.
