Tilman Hausherr commented on PDFBOX-5093:
-----------------------------------------
"Set a custom PDF renderer to PDFPrintable" sounds like dependency injection so
it makes sense. Also because of the class comment in PageDrawer. I need more
time to think about the rest, but I remember your name from PDFBOX-3665, that
helped us a lot.
> Pass PDFRenderer to PDFPrintable constructor

> Key: PDFBOX-5093
> URL: https://issues.apache.org/jira/browse/PDFBOX-5093
> Project: PDFBox
> Issue Type: Improvement
> Components: Rendering
> Reporter: Alexander
> Priority: Minor
>
> I prepared a simple example for PDFBOX-4709 "PDFBox prints text poorly in
> comparison to Adobe, Chrome, other apps" which uses a custom PDF renderer and
> PageDrawer to draw a text using Graphics2D.drawString(...) method to print a
> low DPI text with good quality.

> https://github.com/AlexanderScherbatiy/pdfbox/commit/b806d44f9514a7b5fededfa49c98ad2858b93a92
> The sample is prepared for tag 2.0.22. It consists of
> org.apache.pdfbox.examples.strprinting.StringPrinting sample which sets a
> custom StringPDFPageable. StringPDFPageable just a copy of PDFPageable
> (PDFPageable is a final class, it is not possible to override it) where
> getPrintable(int i) method sets a custom StringPDFRenderer to PDFPrintable.
> StringPDFRenderer just returns a custom StringPageDrawer which is subclass of
> PageDrawer.
> The aim if StringPageDrawer is an illustration how Graphics2D.drawString(...)
> can be used.
> Only two fonts PDType0Font and PDType1Font are handled by StringPageDrawer.
> The code for PDFont AwtFont handling just a copy from PDFBOX 1.8.
> There are a few things which PDFBOX does not provide as a public API.
> The current request is to provide a way to set a custom PDF renderer to
> PDFPrintable.
> Here is patch which illustrate how it can look like:
>
> https://github.com/AlexanderScherbatiy/pdfbox/commit/212a78b2b65ada117c0e9ae65c3ae6054ca5fa61
> The other two things are private setClip() and getNonStrokingPaint() methods
> from PageDrawer. The idea of the sample was to draw a text in the same way
> as PDFBOX renderingMode.isFill() (the same transform, clip and paint) only
> changing graphics.fill(glyph) to graphics.drawString(str, 0, 0).
> Is it possible to make setClip() and getNonStrokingPaint() public in some
> way or it is necessary just to copy them as is?
