Not text, not image

[RuiBarbosa]

Good afternoon.

We tried to extract the barcode image from a document but were unable to do so.

In the file there is an interleaved barcode and a QRCode. Extracting the QRCode image using the PdfPageBase.ExtractImages() command worked perfectly. But in interleaved barcode no. We also do not identify it as text. What is the interleaved bar code in this PDF?

Thank you for your attention,

Rui Barbosa

Hello,

Thank you for your inquiry.
After analyzing your PDF document, we found that the barcode is fundamentally drawn using paths, with a transparent image overlaid on top of it. As a result, extracting the barcode as an image has been unsuccessful. This issue is caused by the structure of your document's content, and it is not a bug or limitation of our product.
Thank you for your understanding.

Sincerely,

Hello Annika.

We didn't think it was a bug either. The question was what object would be inside the PDF.

We appreciate your attention and your precise explanation. We will take another approach to resolve the issue. Can SpirePDF convert an internal PDF path to a JPG?

Hello,

Thank you for your feedback.
Our Spire.PDF supports converting PDF files to JPG images. Please refer to the following example code.

Code: Select all

PdfDocument doc = new PdfDocument();
doc.LoadFromFile(@"Document.pdf");
Image image = doc.SaveAsImage(0);
image.Save("output.jpg", ImageFormat.Jpeg);

Alternatively, you can refer to this tutorial for more information.
