2020-10-31lcd_framebuffer bugfixes, sanity checksWilliam Wilgus1-3/+3
several issues I saw that could pontentially cause problems scroll engine doesn't take text height into account when checking bounds NBELEMS was one whole row too large hopefully I got them right this time Change-Id: If303da8320429c3964fc675351cb088d46303745
2020-10-26LCD core move buf ptr and address look up function viewport structWilliam Wilgus1-36/+38
I'm currently running up against the limitations of the lcd_draw functions I want these functions to be able to be used on any size buffer not just buffers with a stride matching the underlying device [DONE] allow the framebuffer to be decoupled from the device framebuffer [DONE need examples] allow for some simple blit like transformations [DONE] remove the device framebuffer from the plugin api [DONE}ditto remote framebuffer [DONE] remove _viewport_get_framebuffer you can call struct *vp = lcd_set_viewport(NULL) and vp->buffer->fb_ptr while remote lcds may compile (and work in the sim) its not been tested on targets [FIXED] backdrops need work to be screen agnostic [FIXED] screen statusbar is not being combined into the main viewport correctly yet [FIXED] screen elements are displayed incorrectly after switch to void* [FIXED] core didn't restore proper viewport on splash etc. [NEEDS TESTING] remote lcd garbled data [FIXED] osd lib garbled screen on bmp_part [FIXED] grey_set_vp needs to return old viewport like lcd_set_viewport [FIXED] Viewport update now handles viewports with differing buffers/strides by copying to the main buffer [FIXED] splash on top of WPS leaves old framebuffer data (doesn't redraw) [UPDATE] refined this a bit more to have clear_viewport set the clean bit and have skin_render do its own screen clear scrolling viewports no longer trigger wps refresh also fixed a bug where guisyncyesno was displaying and then disappearing [ADDED!] New LCD macros that allow you to create properly size frame buffers in you desired size without wasting bytes (LCD_ and LCD_REMOTE_) LCD_STRIDE(w, h) same as STRIDE_MAIN LCD_FBSTRIDE(w, h) returns target specific stride for a buffer W x H LCD_NBELEMS(w, h) returns the number of fb_data sized elemenst needed for a buffer W x H LCD_NATIVE_STRIDE(s) conversion between rockbox native vertical and lcd native stride (2bitH) test_viewports.c has an example of usage [FIXED!!] 2bit targets don't respect non-native strides [FIXED] Few define snags Change-Id: I0d04c3834e464eca84a5a715743a297a0cefd0af
2014-01-12put_line/scrolling: Make the scroll engine inform custom scrollers about ↵Thomas Martitz1-2/+2
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
2014-01-07lcd-common/scroll_engine: Remove unused functions lcd_puts_style_xyoffset() ↵Thomas Martitz1-6/+0
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.

2014-01-07lcd-common/scroll_engine: Introduce lcd_putsxy_scroll_func().Thomas Martitz1-0/+3
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.

2012-02-28lcd/skin_engine: Add the ability to draw onto the backdrop layerJonathan Gordon1-0/+1
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
2012-02-28lcd drivers: Convert lcd_[remote_]framebuffer to a pointerJonathan Gordon1-1/+4
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!)

2008-12-26Latest work on the bmp on-load scaler:Andrew Mahone1-0/+4
Macros for calculating size needed for bitmap load and scaling, so that these can be compile-time constant when their inputs are. Reduce size of bayer dither by chopping all but first row of dither matrix, and replacing 2D lookup with 1D lookup and small calculation. Move some functions not related to actual bmp file loading out of bmp.c. A smaller brightness() for mono targets, and a higher-quality one for greyscale targets, both replacing the division by 10 with a shift. Port of the linear and area scalers to greyscale targets, this costs some binsize but produces better output even when dithered to 2bpp. Move duplicated row output code from inside vertical scalers to a separate row output function. Move some multiplies out of the line scaler, for a small speedup and code size reduction, as well as a small improvement in accuracy for the upscaling case. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@19592 a1c6a512-1295-4272-9138-f99709370657

2008-06-23FS#9051 - remove LCD margins... use viewports if you need them...Jonathan Gordon1-3/+0
NOTE to WPS people.... %m has been removed, but (i think) because of the other %m tags it wont fail if you try loading a wps with %m|..|, it will just be ignored. Also note that if the statusbar is enabled the default viewport is 8 pixels shorter than when its not, i.e (0,0) is really (0,8) if the statusbar is shown... I dont think this will be a major issue because almost no WPS show the bar and use bitmaps... text only WPS shouldnt be affected.
