Ability to drawString to an externally defined buffer #286

Closed PR77 closed 3 years ago

PR77 commented 4 years ago

Aim: To be able to render a long string (larger than the display size) to an external buffer as a "bitmap" and then display a suitable portion of the bitmap on the display.

I have looked into the draw functions and considered writing my own which uses the Font Tables to render a char string to an external buffer. I would then display the buffer as a "bitmap" to the display, and scrolling it pixel-by-pixel every x(ms).

I have a very long string of variable length which will not fill on the screen (even when using drawStringMaxWidth) and I do not want (but open to suggestions) to truncate the string into sections (String().SubString() is very slow). So if the string could be rendered to memory I could display as a bitmap with different start and size parameters.

Any ideas or suggestions?
