Attributes

Name Type g/s Description
anchor_x int The horizontal anchor point for rotation (default = 0) The anchor point is horizontally offset in pixels from the upper left corner of the display.
anchor_y int The vertical anchor point for rotation (default = 0) The anchor point is vertically offset in pixels from the upper left corner of the display.
boundmode int Boundary handling mode (default = 0 (ignore))
0 = ignore: Values that exceed the limits are ignored.
1 = clear: Values that exceed the limits are set to 0.
2 = wrap: Values that exceed the limits are wrapped around to the opposite limit with a modulo operation. (256 wraps to 0, 257 wraps to 1, and -1 wraps to 255, -2 wraps to 254, etc.)
3 = clip: Values are limited not to exceed min or max. (e.g. numbers greater than 255 are set to 255, and numbers less than 0 are set to 0.)
4 = fold: Values that exceed the limits are folded back in the opposite direction. (256 is folded back to 254, 257 is folded back to 253, and -1 is folded back to 1, -2 to 2, etc.)
cosoffset_x float Horizontal cosine offset (default = 0.)
cosoffset_y float Vertical cosine offset (default = 0.)
cosscale_x float Horizontal cosine scale (default = 0.)
cosscale_y float Vertical cosine scale (default = 0.)
interp int Interpolation flag (default = 0) When the flag is set, the incoming matrix is interpolated when scaling to display.
offset_x int The horizontal offset (default = 0) The horizontal offset is specified in pixels from the upper left corner of the display.
offset_y int The vertical offset (default = 0) The vertical offset is specified in pixels from the upper left corner of the display.
sinoffset_x float Horizontal sine offset (default = 0.)
sinoffset_y float Vertical sine offset (default = 0.)
sinscale_x float Horizontal sine scale (default = 0.)
sinscale_y float Vertical sine scale (default = 0.)
theta float The rotation angle in radians (default = 0.)
thetaoffsetcos_x float theta-dependent horizontal cosine offset (default = 0.)
thetaoffsetcos_y float theta-dependent vertical cosine offset (default = 0.)
thetaoffsetsin_x float theta-dependent horizontal sine offset (default = 0.)
thetaoffsetsin_y float theta-dependent vertical sine offset (default = 0.)
thetascalecos_x float theta-dependent horizontal cosine scale (default = 0.)
thetascalecos_y float theta-dependent vertical cosine scale (default = 0.)
thetascalesin_x float theta-dependent horizontal sine scale (default = 0.)
thetascalesin_y float theta-dependent vertical sine scale (default = 0.)
zoom_x float The horizontal image scaling (default = 1.)
zoom_y float The vertical image scaling (default = 1.)
