Problem converting to Pdf, Pdf/a documents with images with transparencies

Aspose.Words Product Family
1

Good morning,

I wanted to bring the following case study to your attention:
I’m trying to convert a document produced with Microsoft Word to PDF/A.
In the document there is a blue background on which 3 images with transparent backgrounds and white writing have been applied.
During the conversion the images are not visible, a white background is generated within the blue background.
By copying the image with the blue background into an editing program such as “paint” and saving it as a single image and then reinserting it into the document, the conversion is carried out correctly.

Is there any setting in Microsoft Word that needs to be set to then carry out a correct conversion in aspose so that images “with transparency” are converted correctly?

Sample documents are attached.

The version I’m using is 22.12. I await your response, thank you.

Thank you.

Could you please specify the exact settings you are using in Microsoft Word for the images with transparency? Additionally, are you using any specific options in Aspose.PDF for the conversion?

I don’t use any particular options in Aspose.
Even in Microsoft Word the document is created with the basic settings, to which I apply, in the page header, a blue background and then I add the 3 images to the background. (see the word document I attached above).
Thank you.

@L1b3r0 The problem is not reproducible on my side using the latest 25.1 version of Aspose.Words for Java and the following simple code:

Document doc = new Document("C:\\Temp\\in.docx");
doc.save("C:\\Temp\\out_java.pdf");

Here is the produced output: out_java.pdf (78.2 KB)

So, please try using the latest version on your side and let us know if the problem still persists.
