Random Image with black background is generated

Issue Description Using the pdftohtml generated an XML from the PDF. However, an image with black background is generated PHT3-1_8.png. When building an HTML out of this file, this leads to other elements on the page becoming invisible.

Working Files:

• PDf used PHT3.pdf for conversion.
• Generated XML file: PHT3.xml
• Extracted Images: PHT3.zip

Would be great if you could share your advice on how to resolve this.

Attaching more information just in case it helps.
