Hello, we’re running odg->pdf conversion. To test the limits, we’ve created quite a large odg file (in attachment). When running the conversion, Aspose throws NullPointerException:

java.lang.NullPointerException

Here’s the code we use. Smaller files are handles fine
:

        var image = Image.load(is);
        final OdgRasterizationOptions rasterizationOptions = new OdgRasterizationOptions();
        //without setting the size, the Apose generates corrupted files
        rasterizationOptions.setPageSize(new SizeF(image.getWidth(), image.getHeight()));

        var outputStream = new ByteArrayOutputStream();
        var options = new PdfOptions();
        options.setVectorRasterizationOptions(rasterizationOptions);
        image.save(outputStream, options);
        return outputStream.toByteArray();

The questions are:

  1. what’s the reason of the failure?
  2. if size of the file, what are the limitation? if some elements aren’t supported, please let us know which.

large-odg.zip (5.8 MB)

@astafev

Can you please try using latest Aspose.Imaging for Java on your end. Can you please also set the Heap Size to above 2 GB. Please test the following code as well.

try (Image image = Image.load("large-odg.odg"))
{
    final OdgRasterizationOptions rasterizationOptions = new OdgRasterizationOptions();
    rasterizationOptions.setPageSize(new SizeF(image.getWidth(), image.getHeight()));
    ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
    PdfOptions options = new PdfOptions();
    options.setVectorRasterizationOptions(rasterizationOptions);
    image.save(outputStream, options);
}
