Resolution enhancement may be performed internally during image conversions. It involves a doubling of the resolution of a bitonal image resulting from an implicit secondary image conversion from grayscale or color. The doubling is performed on the basis of information available from the greater pixel depth in grayscale and color images. The resulting bitonal image exists in parallel with the original image, and is not available to the application.
The application has no control over when resolution doubling is done, only on whether and how it is done. The ResEnhancementMode Property accepts one of three settings from ImGearRecResEnhancementMode Enumeration:
