Detailed Description

Enumeration Type Documentation

strong

the format of the canvas

Enumerator
MONO_VLSB	monochrome canvas, pixel arranged vertically, LSB is top pixel. Note example: SSD1306
MONO_HLSB	monochrome canvas, pixel arranged horizontally, LSB is left pixel Note example: SH1106
MONO_HMSB	monochrome canvas, pixel arranged horizontally, MSB is left pixel Note example: ST7735 in 1-bit mode
RGB_COLOR_INDEX_8b	color canvas, 8-bit/pixel coded according to ColorIndex in color565_palette. Converted to RGB565 just before being sent to display device. Note example: ST7735 in 16-bit mode
RGB565_16b	color canvas, 16bits/pixel arranged 5b-red,6b-green,5b-blue stored in buffer. This is to allow the use of 16bit DMA. Note example: ST7735 in 16-bit mode with transfer from canvas done by DMA. In this case the canvas buffer format Canvas::RGB565_16b is directly compatible with the ST7735 16-bit mode.
