This is a C# .NET solution that tests and illustrates the capabilities of Xsl-FO for dynamically generating PDF documents. It provides a way to generate the XSL-FO source xml from Xslt or Razor Templating to address various development teams. And it provides basic WinForms Application that can be used to aid in developing the Xslt and Xsl-FO markup.

pdftemplating.xslfo's Issues

System.InvalidCastException from 'Fonet.Layout.BlockArea' to 'Fonet.Layout.AreaContainer'

I have tested the XslFO.ViewerApplication with the Apache FOP Examples https://xmlgraphics.apache.org/fop/examples.html and some of them throw a System.InvalidCastException

STR
1- Run XslFO.ViewerApplication
2- Load Xsl-FO Source file: fop-2.3\examples\fo\basic\images.fo

Expected result
The pdf file is generated

Actual result

[XslFORenderer] System.InvalidCastException: No se puede convertir un objeto de tipo 'Fonet.Layout.BlockArea' al tipo 'Fonet.Layout.AreaContainer'.
   en Fonet.Fo.Flow.BlockContainer.Layout(Area area)
   en Fonet.Fo.Flow.Block.Layout(Area area)
   en Fonet.Fo.Flow.Flow.Layout(Area area, Region region)
   en Fonet.Fo.Flow.Flow.Layout(Area area)
   en Fonet.Fo.Pagination.PageSequence.Format(AreaTree areaTree)
   en Fonet.StreamRenderer.Render(PageSequence pageSequence)
   en Fonet.Fo.FOTreeBuilder.EndElement()
   en Fonet.Fo.FOTreeBuilder.Parse(XmlReader reader)

Notes
Removing the fo:block-container element from the .fo file renders the pdf file as expected:

<fo:block-container width="40mm" background-color="lightgray">
   <fo:block><fo:external-graphic src="../graphics/asf-logo-nt.png" width="100%" content-width="scale-to-fit" content-height="100%" border="solid 0.1pt" background-color="yellow"/> 
   </fo:block>
</fo:block-container>

By the way, nice development!

cannot use because of dependencies for PdfTemplating.XslFO NuGet package

Please note that the NuGet package page says that there are no dependencies,

https://www.nuget.org/packages/PdfTemplating.XslFO.Xslt/

But when I test the demo app without having Adobe Acrobat Reader installed, I receive this error:

https://imgur.com/a/EBKfO4e

According to this page my company would then need to apply for a license from Adobe. This means I am unable to use the software:

https://acrobat.adobe.com/us/en/acrobat/pdf-reader/volume-distribution.html?readstep

So clearly there are dependencies. What do you suggest? TIA.

NullReferenceException when pageReference is null

Hi,
I've just started to use the library but I am getting a NullReferenceException which appears to be because the pageReference is null and then added to the PdfArray in PdfGoTo Write method.

I think this is because it is set to null in IDNode CreateInternalLinkGoTo.

When it is set to null in this way, is the code expecting the pageReference to be set some other way after the instantiation of the PdfGoTo object?

It sounds like I may have a link to a document element that cannot be found? Any ideas how I can diagnose this?

Thanks,

John

Is fo:table supported?

Hi,
I am migrating an existing report to c#. Inside our FO-File we are using fo:table and corresponding tags.
Unfortunatly I cannot see the table in the resulting pdf.

Are Tables just not supported?

(I am using the exact same files with java as well and the table is rendered.)
