Damien George	b15348415e	extmod/modframebuf: Add support for blit'ing read-only data. ... Currently the `FrameBuffer.blit(buf, x, y)` method requires the `buf` argument to be another `FrameBuffer`, which is quite restrictive because it doesn't allow blit'ing read-only memory/data. This commit extends `blit()` to allow the `buf` argument to be a tuple or list of the form: (buffer, width, height, format[, stride]) where `buffer` can be anything with the buffer protocol and may be read-only, eg `bytes`. Also, the palette argument to `blit()` may be of the same form. The form of this tuple/list was chosen to be the same as the signature of the `FrameBuffer` constructor (that saves quite a bit of code size doing it that way).

TPReal	859d0e9529	docs/library/framebuf: Clarify docs for blit regarding palette. ... Clarified the behaviour when both key and palette are specified.	2022-11-17 23:18:22 +11:00
Mat Booth	04a655c744	extmod/modframebuf: Add polygon drawing methods. ... Add method for drawing polygons. For non-filled polygons, uses the existing line-drawing code to render arbitrary polygons using the given coords list, at the given x,y position, in the given colour. For filled polygons, arbitrary closed polygons are rendered using a fast point-in-polygon algorithm to determine where the edges of the polygon lie on each pixel row. Tests and documentation updates are also included. Signed-off-by: Mat Booth <mat.booth@gmail.com>	2022-08-19 23:31:28 +10:00

Jim Mussared	127b340438	extmod/modframebuf: Add fill argument to rect(). ... We plan to add `ellipse` and `poly` methods, but rather than having to implement a `fill_xyz` version of each, we can make them take an optional fill argument. This commit add this to `rect` as a starting point. Signed-off-by: Jim Mussared <jim.mussared@gmail.com>	2022-08-19 23:31:28 +10:00
Sebastian Wicki	8f3510799d	docs/library/framebuf.rst: Adjust dimensions in example. ... This commit swaps the dimensions of the `framebuffer.FrameBuffer` in the docs example from 10x100 to 100x10 pixels to avoid clipping. This is done to better fit the subsequent example code, which writes text of size 96x8 followed by a 96x1 horizontal line. The y coordinate of the horizontal line is also adjusted such that it is drawn inside of the new canvas bounds.	2021-11-17 14:36:33 +11:00
Peter Hinch	2296df0a32	extmod/modframebuf: Enable blit between different formats via a palette. ... This achieves a substantial performance improvement when rendering glyphs to color displays, the benefit increasing proportional to the number of pixels in the glyph.	2021-08-25 15:31:23 +10:00
Peter Hinch	88cbfd791a	docs/library: Fix framebuf monochrome 1-bit modes, swapping HLSB/HMSB. ... This fix can be demonstrated by the following: b = bytearray(32) f = framebuf.FrameBuffer(b, 32, 8, framebuf.MONO_HLSB) f.pixel(0, 0, 1) print('MONO_HLSB', hex(b[0])) b = bytearray(32) f = framebuf.FrameBuffer(b, 32, 8, framebuf.MONO_HMSB) f.pixel(0, 0, 1) print('MONO_HMSB', hex(b[0])) Outcome: MONO_HLSB 0x80 MONO_HMSB 0x1	2020-02-10 23:04:15 +11:00
