The following values are used by rotatesprite, rotatesprite16, rotatespritea, screentext, gametext, minitext, digitalnumber, digitalnumberz, myos and myospalx.

Exposed Value Label Description
No 1 RS_TRANS1 Translucency level one (66% opacity).
No 2 RS_AUTO Scaling on 320-200 coordinates. This is implicitly applied to all CON screen drawing commands, but including it in your bitfields is recommended for clarity and portability of your code.
No 4 RS_YFLIP Used to invert Y coordinates. Combine this bit with an angle of 1024 (using rotatesprite) and the tile will appear to have inverted X coordinates. If you want inversion for both the X and Y coordinates, simply set the angle (again, with rotatesprite) to 1024 and do not use this bit.
No 8 RS_NOCLIP Causes the sprite to be not affected by the screen size (using the + or - commands). This is usefull, for example, when displaying a status bar.
No 16 RS_TOPLEFT Forces the center of the sprite you're drawing to its top-left if set. It also ignores the x-y offset of the tile.
No 32 RS_TRANS2 Translucency level two (33% opacity). It won't work if 1 is not set.
No 64 RS_NOMASK Forces masking off if set. It discards translucency too.
No 128 RS_PERM "Permanent" tile (deprecated).
No 256 RS_ALIGN_L Align to the left (widescreen support)
No 512 RS_ALIGN_R Align to the right (widescreen support)
No 1024 RS_STRETCH Stretch to screen resolution (distorts aspect ratio; this is the behavior of rotatesprite prior to widescreen awareness)
No 2048 ROTATESPRITE_FULL16 Always interpret coordinate values as having "full" precision, bit-shifted left by 16, so that 20971520x13107200 corresponds to 320x200. See rotatesprite16.
No 4096 RS_LERP Enables interpolation of coordinates between rotatesprite calls per guniqhudid. Changes of tilenum reset interpolation.
No 8192 RS_FORCELERP Forces interpolation, even if the tilenum changes between calls.

As with cstat, the bit values can be added together and used in combination. For example, orientation 33 (32+1) is transparency level two, and orientation 5 (4+1) is transparency level one with inverted Y coordinates.
