Comments
When a function that gets a bitmap from a data set is called, such as LDicomDS::GetImage or LDicomDS::GetImageList, LEADTOOLS may pre-process the image data in the bitmap handle for optimal display. Call the LDicomDS::GetKeepPixelDataIntactFlag function to determine whether LEADTOOLS will pre-process the image data. By default LEADTOOLS pre-processes the image data.
Calling the LDicomDS::SetKeepPixelDataIntactFlag function with bSet set to TRUE stops LEADTOOLS from pre-processing the image data in the bitmap handle. Please note that this may result in unexpected behavior when a LEADTOOLS display or image processing function is called for that bitmap handle.
