_fb_gray_8to4 seems to convert a 8 bit buffer data object into a 4 bit one for older 4 bit kobos.
_fb_Gray4toRGB565 seems to convert it to RGB (why?)
_fb_Gray8toRGB565 as well but for a 8 bit FB
_fb_RGB565toGray4 as well but for a 4 bit FB
_fb_gray_4to8 Convert a gray 4 bit buffer to a 8 bit one for a kobo with a 8 bit FB
epdfbdc_create_ex2 seems to create a FB from a data stream?
epdfbdc_create_ex Does the above?
epdfbdc_create Does the above?
epdfbdc_delete destroys frame buffer
epdfbdc_fbimg_normallize normalizes a FB
_pixel_value_convert converts a pixel value (used for converting FB?)
_epdfbdc_get_dcimg_ptr ??? May convert image to FB?
_epdfbdc_get_img_pixelvalue_from_ptr get pixel data from pointer
_epdfbdc_set_dcpixel_at_ptr Change pixel data with pointer
_epdfbdc_get_img_pixelvalue Gets pixel values of whole image and returns them for use to print to screen?
_epdfbdc_set_pixel sets pixel in provided FB?
epdfbdc_put_fbimg push's image to frame buffer
epdfbdc_get_rotate_active checks if rotating FB
epdfbdc_set_pixel set pixel in FB
epdfbdc_dcbuf_to_RGB565 ???
epdfbdc_get_dirty_region used for dirty region update method
epdfbdc_rotate rotates FB?
epdfbdc_set_host_dataswap Creates swap for FB?
epdfbdc_set_drive_dataswap repeated?
epdfbdc_set_skip_pixel sets pixel to skip?
All of them also seem to put a debug out possibly on the internal serial connector. Probably for debug during development
