I want to suggest some improvements for PdfHandler:
- Respect page rotation (fix for Bug 22194 - pdfinfo doesn't respect it) - it's very simple to get page information from PHP code, so I've done it.
- Direct rendering without ImageMagick rescaling step, also fixes possible memory/tempfile/performance issues on high DPIs.
- Ghostscript options for better rendering (-dUseCropBox -dTextAlphaBits=4 -dGraphicsAlphaBits=4)
- Thumbnails now link to correct individual pages of PDF.
I have commit access to extensions now, am I allowed to create my own branch for review? Or where should I commit my work for review? (The most dubious of all this is probably the multiple page thumbnail feature)
