Dicom Resize Bug

Aspose.Imaging Product Family

Aspose Imaging 17.12.

Loading an DICOM image and saving it to PNG works as expected:

Image image = Image.load("…");
image.save("…", new PNGOptions());

but saving the file fails if I resize the image before:

Image image = Image.load("…");
image.resizeHeightProportionally(300, ResizeType.LanczosResample);
image.save("…", new PNGOptions());

IM-0001-0001.dcm.zip (38.2 KB)

public class DcmTest {

public static void DcmTestWorks()
{
    try {
        Image image = Image.load("IM-0001-0001.dcm");
        
        image.save(new FileOutputStream("IM-0001-0001.png"), new PngOptions());

        image.dispose();

    } catch (Exception e) {
        e.printStackTrace();
    }

}

public static void DcmTestFails()
{
    try {
        Image image = Image.load("IM-0001-0001.dcm");

        image.resizeHeightProportionally(300, ResizeType.LanczosResample);

        image.save(new FileOutputStream("IM-0001-0001.png"), new PngOptions());

        image.dispose();

    } catch (Exception e) {
        e.printStackTrace();
    }

}


public static void main(String[] args) {
    
    DcmTestFails();
    
}
}
