[ome-devel] set pixels size Java API

[Thomas Boudier]

Dear OMERO developers,

I would like to update the pixels sizes for some images, I tried to
convert in Java the code posted here
https://www.openmicroscopy.org/community/viewtopic.php?f=6&t=7616&p=16966&hilit=pixel+size#p16966

but it does not seem to work, there is no error, but the pixels sizes of
the image is not updated in OMERO :

public boolean setResolutionImageUM(ImageData imageData, double resXY,
double resZ) {
         try {
             // get the pixels
             RawDataFacility rdf =
gateway.getFacility(RawDataFacility.class);
             PixelsData pixels = imageData.getDefaultPixels();
             // change their properties
             Length pixelsX = pixels.getPixelSizeX(UnitsLength.MICROMETER);
             pixelsX.setValue(resXY);
             pixelsX.setUnit(UnitsLength.MICROMETER);
             Length pixelsY = pixels.getPixelSizeY(UnitsLength.MICROMETER);
             pixelsY.setValue(resXY);
             pixelsY.setUnit(UnitsLength.MICROMETER);
             Length pixelsZ = pixels.getPixelSizeZ(UnitsLength.MICROMETER);
             pixelsZ.setValue(resZ);
             pixelsZ.setUnit(UnitsLength.MICROMETER);
             // update database
gateway.getUpdateService(securityContext).saveObject(pixels.asIObject());
         } catch (ExecutionException e) {
             e.printStackTrace();
             return false;
         } catch (BigResult bigResult) {
             bigResult.printStackTrace();
             return false;
         } catch (DSOutOfServiceException e) {
             e.printStackTrace();
             return false;
         } catch (ServerError serverError) {
             serverError.printStackTrace();
             return false;
         }

         return true;
     }

Thanks for any help.

Best,

Thomas
