Setting s
to true will clear the stencil buffer of the FT8xx to the preset value. Setting this bit to false will maintain the stencil buffer of the FT8xx with an unchanged value. The preset value is defined in command CLEAR_STENCIL.
Setting t
to true will clear the tag buffer of the FT8xx to the preset value. Setting this bit to false will maintain the tag buffer of the FT8xx with an unchanged value. The preset value is defined in command CLEAR_TAG.

) is the top-left pixel of the text. OPT_CENTERX centers the text horizontally, OPT_CENTERY centers it vertically. OPT_CENTER centers the text in both directions. OPT_RIGHTX right-justifies the text, so that the x
is the rightmost pixel. By default the number is displayed with no leading zeroes, but if a width 1-9 is specified in the options
, then the number is padded if necessary with leading zeroes so that it has the given width. If OPT_SIGNED is given, the number is treated as signed, and prefixed by a minus sign if negative.
x | x-coordinate of text base, in pixels |
