Arguments:
| Name | Type | Description |
| hIGear | HIGEAR | 16g image to have its LUT16x8 updated. |
| lpRect | AT_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. |
| lpWindow_center | LPAT_INT64 | Window Center (0028,1050) as 64 bit integer. |
| lpWindow_width | LPAT_INT64 | Window Width (0028,1051) as 64 bit integer. |
Return Value:
Returns the number of ImageGear errors that occurred during the function call.
Supported Raster Image Formats:
Grayscale – 8…32 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. Use this function for 17-32 bit grayscale images. Although you can also use this function for 8-16 bit images, performance may be affected in 32 bit operation systems.
