Hallo,
we have stumbled upon an problem with saving files using MITK.
Image files are not saved (Windows 7, QT 4.8.4) because
QFileDialog::getSaveFileName (in QmitkIOUtil
::GetFileNameWithQDialog()) always returns a file name with an ".pic," attached
to the end and therefore mitkImageWriter neglects it as no valid extension.
The windows dialog (qfiledialog_win.h) called by QFileDialog always(!) adds
".pic,"; it is irrelevant if the proposed file name has already an extension.
So the default file name is "[yourFilePath].nrrd.pic," and the extension
checked and rejected by mitkImageWriter is ".nrrd.pic,".
Is this a known bug already? It is not fixed by the patches for bug 15480 and
bug 13455.
If not, I would file a bug.
One detail:
The filter string passed to QT is
"Image (*.pic, *.pic.gz, *.bmp, *.dcm, *.DCM, *.dicom, *.DICOM, *.gipl,
*.gipl.gz, *.mha, *.nii, *.nii.gz, *.nrrd, *.nhdr, *.png, *.PNG, *.spr, *.mhd,
*.vtk, *.vti, *.hdr, *.png, *.tif, *.jpg)"
qt_make_filter_list splits on ";;" or "\n".
Then qt_win_extract_filter tries to extract the filters, splits at " " and
concats all items with ";".
This results in the following filter string:
"Image;(*.pic,;*.pic.gz,;*.bmp,;*.dcm,;*.DCM,;*.dicom,;*.DICOM,;*.gipl,;*.gipl.gz,;*.mha,;*.nii,;*.nii.gz,;*.nrrd,;*.nhdr,;*.png,;*.PNG,;*.spr,;*.mhd,;*.vtk,;*.vti,;*.hdr,;*.png,;*.tif,;*.jpg)"
Which explains the ".pic,"
A question rises, without the guarantee to remove the problem completely:
Should the filter string of the mitkImageWriter should be QT compliant?
This would be
"Image (*.pic *.pic.gz *.bmp *.dcm *.DCM *.dicom *.DICOM *.gipl *.gipl.gz *.mha
*.nii *.nii.gz *.nrrd *.nhdr *.png *.PNG *.spr *.mhd *.vtk *.vti *.hdr *.png
*.tif *.jpg)" (so without comma).
Kind regards.
