Identifies image anti-aliasing modes.
 |
IG_DSPL_ANTIALIAS_PRESERVE_BLACK, IG_DSPL_ANTIALIAS_PRESERVE_WHITE and IG_DSPL_ANTIALIAS_SCALE_TO_GRAY are mutually exclusive. |
| IG_DSPL_ANTIALIAS_COLOR | Enables anti-aliasing for downscaled display of non-bitonal images. |
| IG_DSPL_ANTIALIAS_NONE | Anti-aliasing is disabled. |
| IG_DSPL_ANTIALIAS_PRESERVE_BLACK | Directs ImageGear to preserve black pixels when drawing. Only applicable to downscaled display of bitonal images. |
| IG_DSPL_ANTIALIAS_PRESERVE_WHITE | Directs ImageGear to preserve white pixels when drawing. Only applicable to downscaled display of bitonal images. |
| IG_DSPL_ANTIALIAS_RESAMPLE_BILINE | Enables bi-linear interpolation for upscaled display. |
| IG_DSPL_ANTIALIAS_SCALE_TO_GRAY | Directs ImageGear to use scale to gray algorithm. Only applicable to downscaled display of bitonal images. The image is rendered as 4 bits per pixel grayscale. |
| IG_DSPL_ANTIALIAS_SUBSAMPLE | Directs ImageGear to use sub-sampling during anti-alias scaling. The output quality is higher and the display speed is considerably faster. Only applicable to downscaled display of bitonal images. |
