| 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 | LPLONG | Window Center (0028,1050). |

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_64().
