The XA the image is having an overlay image data.
But me, without searching the method it will be able to indicate the overlay image it is.

====== Image Info ===============
BitsAllocated = 16
BitsStored = 10
HighBit = 9
BitsPerPixel = 16

Overlay Bit Position = 13
Overlay Bit Allocated = 16
Overlay Type = G

Me it sees an overlay it wants.
It wants a sample program or the method which is the possibility of seeing the overlay image.

Sample Image Download

I use LeadTools 13.0.

Thanks: 3 times

LEADTOOLS 14 has built in support for overlays:
An "Overlay Plane" describes graphics or bit-mapped text that is associated with an image or has its own existence within a series. It may also describe a ROI in an Image.
Each "Overlay Plane" is one bit deep (1BPP). Sixteen separate planes may be associated with an image or exist as "Standalone Overlays" in a series.
Overlay pixel data is stored either in "Overlay Data" (60xx, 3000) or embedded in the "Image Pixel Data" (7FE0, 0010).
LEADTOOLS offers a number of functions to manipulate overlays in DICOM datasets.
L_DicomGetOverlayCount can be used to find the number of overlays in the DICOM dataset. Call L_DicomGetOverlayAttributes to retrieve the attributes of an overlay and L_DicomGetOverlayBitmap to retrieve the "Overlay Data" (60xx,3000) for a single-frame overlay or L_DicomGetOverlayBitmapList for a multi-frame one. L_DicomGetOverlayActivationLayer lets you get the activation layer for the overlay.
LEADTOOLS also allows you to insert a new or update an existing overlay. Call L_DicomSetOverlayAttributes to set the attributes of a certain overlay and then call
L_DicomSetOverlayBitmap or L_DicomSetOverlayBitmapList to set its data.
To delete all the elements related to an overlay call L_DicomDeleteOverlay.
