XSL-FO Rendering implementing Apache FOP - Missing Background Images

I'm relatively new to this, so bear with me. I'm stuck on something that should probably be simple... I'm relatively new to this, so bear with me... I've been struggling with this for a few days now and could really use some help. I've been banging my head against this for hours. I'm currently working on generating PDFs from XML using XSL-FO and Apache FOP (version 2.6), but I'm working with an scenario where background images are not rendering as expected in the final output. I've set the background images in my XSL-FO stylesheet using the `background-image` property, but they do not appear in the generated PDF. Here’s a simplified version of my XSL-FO: ```xml <fo:flow flow-name="xsl-region-body"> <fo:block> <fo:instream-foreign-object> <fo:external-graphic src="url('path/to/image.png')" /> </fo:instream-foreign-object> My text here </fo:block> </fo:flow> ``` I have double-checked the path to the image and confirmed that it is correct relative to the output directory. I also ensured that the image exists at that location. However, when I generate the PDF, I only see the text without the background image. I have tried specifying the background image in both the `fo:block` and in a `fo:static-content`, but there was no difference in the output. Additionally, I have looked at the log files generated by FOP and there are no behavior messages related to image rendering. I made sure my XML is valid against the specified schema. Is there a specific configuration or setting in Apache FOP that I might be missing? Any suggestions on best practices for including images in the XSL-FO would be greatly appreciated! This is part of a larger API I'm building. Am I missing something obvious? What am I doing wrong? For reference, this is a production microservice. Any advice would be much appreciated. I'm working on a microservice that needs to handle this.
