I have a multi-frame DICOM image which when loaded into a TImageEnView uses a different window level and width from the values in the DICOM tags. This is because the image uses RescaleIntercept and RescaleSlope values.

However, these values are stored in the Per-Frame Functional Groups Sequence tag group, not the Shared Functional Groups Sequence tag group. It appears that ImageEn will look for RescaleIntercept and RescaleSlope values in the Shared group only.

I can read the values from the Per-Frame group myself. Is there a way I can set the RescaleIntercept and RescaleSlope values manually, then have ImageEn redraw the image using those values?

Thank you in advance.

Hi

Unfortunately there is not a method to redraw the image based on custom RescaleIntercept and RescaleSlope values at this time.

But we'll look into this for a later update.

Hi, thanks for the update. It isn't a big issue, I can always adjust the displayed values.
