While loading an image to the recognition engine's memory space (IG_REC_PID_IMGINPUT process), an image conversion is performed according to the current image conversion mode setting.
The setting specified here will influence what kind of HIG_REC_IMAGE image will be created in the recognition engine's memory, i.e., whether it will be bi-tonal, grayscale, or color.
The following table demonstrates what kind of image will created in the recognition engine as the result of the image loading process.
Primary Image Conversion Mode | Image Source is Bitonal | Image Source is Grayscale | Image Source is Color |
---|---|---|---|
IG_REC_IMG_CONVERSION_SET | bi-tonal | bi-tonal | bi-tonal |
IG_REC_IMG_CONVERSION_NO | bi-tonal | grayscale | color |
IG_REC_IMG_CONVERSION_GLOBAL | bi-tonal | bi-tonal | bi-tonal |
IG_REC_IMG_CONVERSION_GRAY | bi-tonal | grayscale | grayscale |
