Syntax
Members
L_UINT uStructSize
Must be set to sizeof(COMPAREOPTIONS).
L_UINT uThreshold
The range in color values allowed and still be considered the same color. The distance is calculated in Euclidean RGB color space using the following equation:
L_COLORREF crReferenceBackground
The color used to identify the background content within the reference image.
L_COLORREF crReferenceForeground
The color used to identify the foreground content (such as text), within the reference image.
L_COLORREF crModifiedBackground
The color used to identify the background content within the modified image.
L_COLORREF crModifiedForeground
The color used to identify the foreground content (such as text), within the modified image.
L_COLORREF crOutputExternal
The color used in the generated image to indicate pixels which were not part of either image.
L_COLORREF crOutputBackground
The color used in the generated image to indicate pixels which were equivalent to the background in both images.
L_COLORREF crOutputMatch
The color used in the generated image to indicate pixels which were equal in both images.
L_COLORREF crOutputAddition
The color used in the generated image to indicate pixels which were background content in the reference image, but not in the modified image. Additionally, any pixels within the bounds of the modified image but were not within the bounds of the reference image will be marked with this color.
L_COLORREF crOutputDeletion
The color used in the generated image to indicate pixels which were background content in the modified image, but not in the reference image. Additionally, any pixels within the bounds of the reference image but were not within the bounds of the modified image will be marked with this color.
L_COLORREF crOutputChange
The color used in the generated image to indicate pixels which were different in both images (but were neither an addition nor deletion).
