[Ctk-developers] ctkDICOMImage in ctkDICOMDatabase

[Steve Pieper]

Hi Julien -

The idea here is that the ctkDICOMDatabase should be able to
automatically make the thumbnail images (png) on the fly as dicom
files are added.  ctkDICOMImage uses the QImage class to do this,
which is in QtGui even though it seems to me to be a purely data
formatting class, not a display class.  Even though it's still being
debugged, I'm planning to make use of the thumbnail feature in
slicer4's use of ctkDICOM.

Can you think of a way we can encapsulate the thumbnail calculation in
ctkDICOMCore?  Perhaps we should make an abstract thumbnail generator
class in ctkDICOMCore and then have a QImage-based implementation in
ctkDICOMWidgets that is registered with ctkDICOMDatabase at run time.
Alternatively perhaps ctkDICOMDatabase could link directly to the png
library and make the thumbnails with that.

-Steve
