Summary: RFC: Integration of Graphics2D->PDFBox bridge
Key: PDFBOX-3697
URL: https://issues.apache.org/jira/browse/PDFBOX-3697
Project: PDFBox
Issue Type: Improvement
Reporter: Emmeran Seehuber
Priority: Minor
I've build a Graphics2D -> PDFBox bridge. It allows you to draw using
Graphics2D into a PDF. iText has such a feature for a long time now. In
PDFBOX-102 it seems you don't want such a feature, or at least don't want to
implement it. I hope I must not explain why drawing to an image and placing
that image in the PDF is *not* the right solution. Depending on the output
device this may result in horrible quality.
As I want to migrate my usages of flying-saucer to openhtmltopdf
(https://github.com/danfickle/openhtmltopdf) I need a way to embed report
graphs in high quality into the PDF. Because of this I build this bridge:
https://github.com/rototor/pdfbox-graphics2d
The bridge is build from ground up by myself. I did not use any code of the
iText-Graphics2D bridge.
Currently it can render text only as vector shapes. But it supports different
gradient paints and texture paints. openhtmltopdf uses it to draw inline SVGs.
I would like to contribute this bridge to PDFBox, as I think this is a feature
PDFBox currently lacks. But I am not sure if you want this at all.
The bridge uses reflection to access e.g. the Batik gradient paints without
referencing Batik. The paint mapping is something which can never be really
finished, as they can be many paint implementations. Because of this the bridge
allows to customize all different kind of mappings (color/paint/font).
I don't know if it is better to keep this bridge separate or if it is better to
integrate it into PDFBox. This is something I would like you to decide. If you
would like it, I would prepare a patch.
