In This Topic

Builds the 16x8 display LUT, using rescale, Presentation LUT and GSDF LUT.

Declaration:

	Copy Code
AT_ERRCOUNT ACCUAPI MED_PS_display_contrast_auto_double ( HIGEAR hIGear, LPAT_RECT lpRect, DOUBLE rescale_slope, DOUBLE rescale_intercept, DOUBLE gamma, LPAT_MED_LUT_DESC lpPresLUTInfo, LPAT_MED_LUT_DESC lpGSDFLUTInfo, LPAT_DOUBLE lpWindow_center, LPAT_DOUBLE lpWindow_width );

Copy Code

AT_ERRCOUNT ACCUAPI MED_PS_display_contrast_auto_double (
        HIGEAR hIGear, 
        LPAT_RECT lpRect, 
        DOUBLE rescale_slope, 
        DOUBLE rescale_intercept, 
        DOUBLE gamma, 
        LPAT_MED_LUT_DESC lpPresLUTInfo, 
        LPAT_MED_LUT_DESC lpGSDFLUTInfo, 
        LPAT_DOUBLE lpWindow_center, 
        LPAT_DOUBLE lpWindow_width 
);

Arguments:

Name	Type	Description
hIGear	HIGEAR	16g image to have its LUT16x8 updated.
lpRect	LPAT_RECT	set to NULL to scan the entire image.
rescale_slope	DOUBLE	Rescale Slope (0028,1053).
rescale_intercept	DOUBLE	Rescale Intercept (0028,1054).
gamma	DOUBLE	Gamma correction - set to 1.0 to turn off.
lpPresLUTInfo	LPAT_MED_LUT_DESC	Presentation LUT info.
lpGSDFLUTInfo	LPAT_MED_LUT_DESC	GSDF LUT info.
lpWindow_center	LPAT_DOUBLE	Window Center (0028,1050).
lpWindow_width	LPAT_DOUBLE	Window Width (0028,1051).

Return Value:

Returns the number of ImageGear errors that occurred during the function call.

Supported Raster Image Formats:

Grayscale – 8…16 bpp.

Remarks:

Window center and width are calculated automatically, based on min and max values of the image. If lpGSDFLUTInfo parameter is not NULL, gamma is not used.

For 17-32 bits per pixel images, please use MED_PS_display_contrast_auto_double().
