CadStringParameter vales missing

Aspose.CAD Product Family
1
Hello,


I'm using the native Autodesk trueview 2017 viewer and I can see 3 property values as per attached image. The same values seem to be missing when using the aspose-cad-17.02-jdk16.jar which is the latest available now.


I think that the last saved by should be in the header property retrievable by image.getHeader().getHeaderProperties().get(CadHeaderAttribute.LASTSAVEDBY). The retrieved value should be John but it's null.

I'm also looking for the Revision Number and TotalEditingTime prperties but the names of the constants are a little bit cryptic so I need help figuring which one to use.



Thank you

code: try (InputStream inputStream = new ByteRegionInputStream(getByteRegion()))

{
AsposeCad.ensureInitialised();

return Optional.of((CadImage) Image.load(inputStream));
}
…
cadImage.get().ifPresent(
image ->
{
for (Integer key : image.getHeader().getHeaderProperties().keySet())
{
image.getHeader().getHeaderProperties()
.get(key)
.stream()
.filter(o -> o instanceof CadStringParameter)
.forEach(
o ->
{
String value = ((CadStringParameter) o).getValue();
the values shown on the png image are missing
…



Samples attached.


Cheers

This is still an issue . Moreover when switching to the latest release version 17.9 the same code cannot load the image :
try (InputStream inputStream = new ByteRegionInputStream(getByteRegion()))
{
AsposeCad.ensureInitialised();

            // Aspose only supports a sub-set of DWG files, but the data needs to be loaded to check if it is supported
            return Optional.of((CadImage) Image.load(inputStream));
        }

results in:

class com.aspose.cad.cadexceptions.ImageLoadException: Cannot open an image. The image file format may be not supported at the moment.

Again, to be clear:This code works with the old version of the jar but in the old version produces just one non-null metadata called something like cadVersion instead of the many metadata we expect from a Cad image.

Thank you
