Hi,

we recently updated ImageEn from version 4.0.2 to 4.3.1.
In the new version, we get an access violation when loading a dicom image.
For your testing purposes, I'll attach a zip file containing the image.


Please try the following.
Create an empty project and put a TImageEnView object on your form.
In the constructor, put the following code:

myImageEnView->IO->LoadFromFileAuto("R1.rvg");

This will give you an access violation. I tested the same thing in version 4.0.2 and this works with no problems.

Can you please provide a solution?
Thanks!
Steven

Hi,
many thanks for the useful file.
Next minor release will fix this problem. If you want to patch it now please open iedicom.pas and locate the rows (in ReadTag function):
....
          case element of
            $0002:  // Samples per Pixel
              SamplesPerPixel := dataint;
            $0004:  // photometric interpretation
              PhotometricInterpretation := AnsiString(data);
....

before the "case" statement insert:

if tags = IOParams.DICOM_Tags then


Hope this helps.

Hi Fab,

thank you for the quick reply.
I'm afraid it didn't help.

Here is what I did:

I altered the code as follows:
....
if tags = IOParams.DICOM_Tags then case element of
$0002: // Samples per Pixel
SamplesPerPixel := dataint;
$0004: // photometric interpretation
PhotometricInterpretation := AnsiString(data);
....
Then I did a rebuild of
- PKIECtrl15.dpk
- PKIEDB15.dpk

I then retested my exe with the new bpl files.
I still get an access violation.

Sincerely,
Steven Aertssen
