Support of PdfCompliance PDF/A-2 | Transparent PNG Rendering using Java

Hi,


I am having problems with converting Word-Documents to PDF using Aspose Words for JAVA.
The Word-Documents contain PNG-Images with transparent background.
But within the created pdf document the images have a white background. Please see the attached Word- and PDF-File.
The code to reproduce it is very simple:

FileInputStream fin = new FileInputStream(“C:/temp/transparency.docx”);
com.aspose.words.Document asposeDoc = new com.aspose.words.Document(fin);
PdfSaveOptions options = new PdfSaveOptions();
options.setCompliance(PdfCompliance.PDF_A_1_B);
options.setSaveFormat(SaveFormat.PDF);
FileOutputStream fout = new FileOutputStream(“C:/temp/transparency.pdf”);
asposeDoc.save(fout, options);

I could reproduce this issue with the latest Version 16.11 of Aspose Words for JAVA.

Could you please check it?

Thanks in advance.

Stefanie

Hi Stefanie,


Thanks for your inquiry. Please note that Aspose.Words mimics the same behavior as MS Word. If you convert your document to Pdf with PDF/A compliance, you will get the same output. Please use PdfCompliance as PDF_15 to fix this issue.

Dear Tahir,


thank you very much for your response.

Are there any plans at your side to support the PDF/A-2 Format ?
This format allows transparent images.

Thanks in advance
Stefanie
