SetBiometricDisplayColors

Home » Fingerprint SDK 2009 Developer's Manual » Programming Reference Guide » Fingerprint SDK ActiveX Reference Guide » Biometric display methods » SetBiometricDisplayColors

Sets the colors used to draw the minutiae, matching minutiae, segments, matching segments, minutiae directions and matching minutiae directions in the picture returned by the BiometricDisplay method.

Prerequisites

The Fingerprint SDK library must have been previously initialized.

Return

On success, GR_OK is returned.
On failure, the appropriate error code is returned.

Parameters

[in] minutiaeColor	Minutiae color in BGR 24-bits format.
[in] minutiaeMatchedColor	Matching minutiae color in BGR 24-bits format.
[in] segmentsColor	Segments color in BGR 24-bits format.
[in] segmentsMatchedColor	Matching segments color in BGR 24-bits format.
[in] directionsColor	Minutiae direction color in BGR 24-bits format.
[in] directionsMatchedColor	Matching minutiae direction color in BGR 24-bits format.

Remarks

Passing GR_IMAGE_NO_COLOR as any color causes the corresponding feature (minutia, matching minutia, segment, matching segment, minutia direction or matching minutia direction) not being drawn.

Passing all colors as GR_IMAGE_NO_COLOR causes the default colors to be used: red for minutiae, green for segments, blue for minutiae direction and magenta for matching minutiae, segments and minutiae direction.
