VintaSoft PDF .NET Plug-in Discussions

Hi,

Our company is currently evaluating the product whether it will cater to our needs.

Our requirements are as follows:
1) Convert TIFF file to PDF using JBIG2 Compression
2) Convert JPG file to PDF using JPEG2000 Compression

When I tried, I get an error message stating that the compression (Jpeg2000 and Jbig2) is not supported now.

Basing on the documentation provided, below is the code for converting TIFF to PDF (using JBIG2):
ImageCollection imageCollection = new ImageCollection();
imageCollection.Add(tiffFileName);

PdfEncoder pdfEncoder = new PdfEncoder(true);
pdfEncoder.Settings.Compression = PdfImageCompression.Jbig2;
pdfEncoder.Settings.Jbig2Settings.Lossy = false;
imageCollection.SaveSync(pdfFileName, pdfEncoder);

pdfEncoder.Dispose();
imageCollection.Dispose();

Below is the code for converting JPG to PDF (using JPEG2000):
ImageCollection imageCollection = new ImageCollection();
imageCollection.Add(jpgFileName);

PdfEncoder pdfEncoder = new PdfEncoder(true);
pdfEncoder.Settings.Compression = PdfImageCompression.Jpeg2000;
pdfEncoder.Settings.Jpeg2000Settings.CompressionType = Vintasoft.Imaging.Codecs.Jpeg2000.Jpeg2000CompressionType.Lossy;
imageCollection.SaveSync(pdfFileName, pdfEncoder);

pdfEncoder.Dispose();
imageCollection.Dispose();

Is there something I should be doing to make this work or is this feature only supported in future versions? Please note that I'm currently using version 7.0.1.1.

Please advise asap.

Thanks.

Hi Alex,

Thanks! Figured it out. Although I added them as references, they weren't copied to output folder in my test project as they weren't actually called.

The JPG to PDF with JPEG2000 compression is now working fine. But I'm getting this error for the TIFF to PDF (JBIG2):

Vintasoft.Imaging.Codecs.PdfEncoderException: Index must be within the bounds of the List.

The error is thrown by this line of code:

imageCollection.SaveSync(pdfFileName, pdfEncoder);

Found the examples for this and experimented with some settings. I tried to follow what works on the Imaging Converter example by doing this:

pdfEncoder.Settings.Jbig2Settings.Lossy = false;
pdfEncoder.Settings.Jbig2Settings.Inaccuracy = 50;
pdfEncoder.Settings.Jbig2Settings.UseSymbolDictionary = true;
pdfEncoder.Settings.Jbig2Settings.SymbolDictionarySize = 6500;
pdfEncoder.Settings.Jbig2Settings.UseMmr = false;

But I still get the same error Index must be within the bounds of the List.

Am I missing something again?

Best Regards,
Mylene
