virtual |
Given an array of pixels encoded in the nominated format, draw these into the display's buffer.
The naive implementation here will work in all cases, but can be overridden by sub-classes in order to optimise the procedure. The parameters describe a rectangular block of pixels, potentially within a larger buffer.
x_start | The starting destination x position |
y_start | The starting destination y position |
w | the width of the pixel block |
h | the height of the pixel block |
ptr | A pointer to the start of the data to be copied |
order | The ordering of the colors |
bitness | Defines the number of bits and their format for each pixel |
big_endian | True if 16 bit values are stored big-endian |
x_offset | The initial x-offset into the source buffer. |
y_offset | The initial y-offset into the source buffer. |
x_pad | How many pixels are in each line after the end of the pixels to be copied. |
The length of each source buffer line (stride) will be x_offset + w + x_pad.

Get the specified vertex (x,y) coordinates for the regular polygon inscribed in the circle centered on [center_x,center_y] with the given radius.
Vertex id are 0-indexed and rotate clockwise. In a pointy-topped variation of a polygon with a 0° rotation, the vertex #0 is located at the top of the polygon. In a flat-topped variation of a polygon with a 0° rotation, the vertex #0 is located on the left-side of the horizontal top edge, and the vertex #1 is located on the right-side of the horizontal top edge. Use the edges constants (e.g.: EDGES_HEXAGON) or any integer to specify the number of edges of the polygon. Use the variation to switch between the flat-topped or the pointy-topped variation of the polygon. Use the rotation in degrees to rotate the shape clockwise.
