enumIGDsplAliasModes
API Reference Guide > Core Component API Reference > Core Component Enumerations Reference > enumIGDsplAliasModes

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.

Values:

IG_DSPL_ANTIALIAS_COLOR Enables anti-aliasing for downscaled display of non-bi-tonal 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 bi-tonal images.
IG_DSPL_ANTIALIAS_PRESERVE_WHITE Directs ImageGear to preserve white pixels when drawing. Only applicable to downscaled display of bi-tonal 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 bi-tonal 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 bi-tonal images.
