Question
PDF export with images
We have a requirement that in a case, we have a property which is displayed as RTE (i.e. end user can add any HTML code in it including images, tables etc.).
Also they need a way to export this data in PDF format. When we try to use HTMLToPDF and Code-Pega-PDF.View activity , it works fine. Except that it does not get the images from the TE, just have empty space for images.
(also we checked https://community1.pega.com/community/pega-support/question/rte-images-are-not-exporting-pdf-image-title-spaces and confirmed that our RTE images are not having space, as it is copy pasted)
Note: We are using Pega 7.2.1.
What would be the way out for this?

If on the other hand your images *are* already stored in PRPC (DATA-CONTENT-IMAGE instances), and they are not showing up in your converted PDF ; there might be an issue that needs looking into.....
Hi John,
As mentioned, the image is pasted in the RTE and saved in the case. And we are trying to export it to PDF. So its not an external image and should be saved somewhere in Pega db.
When i inspect the img src, it shows like "../datacontent/Image/rteImages/UserUpload_15426908302471542690830983.png"...
What could be the next steps for this?
Please try this:
1. Create a NEW entry using the Rich Text Editor.
2. Use the upload button to insert an image.
3. Try converting that to a PDF.
Does that work ? If this *does* I suspect that the image you have in your particular RTE was *copied* (CTRL-A, CTRL-C from an image editor , then CTRL-V to RTE).
There is a known limitation for this type of image-inclusion (that is: when the image contents are pasted directly into the RTE) - and is already logged as a enhancement request to be considered for inclusion in a future version of PRPC. [ US-170646 ]
Hi Jon,
That is correct if I upload the image in RTE using image uploader, then while exporting it works fine. However when i copy paste the image in RTE and try to export to pdf, it does not show the image.
So technically what is the difference between these? As i see in both scenario, Pega creates an instance of Data-Content-Image in backend. So what is breaking in case of Copy paste?
OK - so I don't know exactly *why* this is the case ; but that is the issue previously identified and logged under "US-170646". I'll make a note on that User Story and point to this discussion.
There isn't a fix for this at this time as far as I'm aware I'm afraid.
HTMLTOPDF should convert and include images in the output PDF - so long as they are hosted/referenced within the PRPC system itself.
If the images are externally hosted; they will not be fetched by the conversion process; and will be missing from the PDF; you would need to fetch them individually yourself and store them in PRPC first.
(There is no guarantee that your PRPC system is allowed [for good security reasons] to access external websites which are hosting images: so just because your desktop browser can access them, this doesn't necessarily mean your PRPC system [or indeed any back-end web app] can see them also).
