Arguments:
| Name | Type | Description |
| hIGear | HIGEAR | ImageGear handle of image. |
| dwGrpID | DWORD | Identifier of group in which to set option. |
| nAliasFlags | AT_MODE |
New value of AliasMode to set. It is an OR combination of following elements:
with OR combination of one additional flag IG_DSPL_ANTIALIAS_SUBSAMPLE Anti-aliasing for all non-1 bit color spaces is activated with the IG_DSPL_ANTIALIAS_COLOR flag. Scale-Up interpolation for all non-1 bit color spaces is specified by the IG_DSPL_ANTIALIAS_RESAMPLE_BILINE flag. |
| nThreshold | INT | It indicates the threshold value of the amount of selected color to include for IG_DSPL_ANTIALIAS_PRESERVE_XXXX scale-down interpolations. Please see Dithering, Anti-Aliasing, and Palette Handling. |
| nColorQuality | INT | Specifies quality of color scale-down interpolation (anti-aliasing). Valid values are from 0 to 100 and specify the percent of image pixels taken into account to produce one display pixel. Zero value means automatic quality choice according with image resolution and display settings. |
Return Value:
Returns the number of ImageGear errors that occurred during this function call.
