EPD_drawPixel Draw pixel at given x,y coordinates
EPD_drawLine Draw line between two points
EPD_drawFastVLine, EPD_drawFastHLine Draw vertical or horizontal line of given lenght
EPD_drawLineByAngle Draw line on screen from (x,y) point at given angle
EPD_drawRect, EPD_fillRect Draw rectangle on screen or fill given rectangular screen region with color
EPD_drawRoundRect, EPD_fillRoundRect Draw rectangle on screen or fill given rectangular screen region with color with rounded corners

If the text does not fit the screen/window width it will be clipped ( if text_wrap=0 ), or continued on next line ( if text_wrap=1 )
Two special characters are allowed in strings:r CR (0x0D), clears the display to EOL, n LF (ox0A), continues to the new line, x=0
Special values can be entered for X position:
CENTER centers the text
RIGHT right justifies the text horizontaly
LASTX continues from last X position; offset can be used:LASTX+n
Special values can be entered for Y:
CENTER centers the text verticaly
BOTTOM bottom justifies the text
LASTY continues from last Y position; offset can be used:LASTY+n
EPD_getStringWidth Returns the string width in pixels based on current font characteristics. Useful for positioning strings on the screen.
EPD_clearStringRect Fills the rectangle occupied by string with current background color
