We can build a new PDF file, given a number of pages and a paper size. The default is one page, A4 portrait.
cpdf -create-pdf -create-pdf-pages 20 -create-pdf-papersize usletterportrait -o out.pdf
The standard paper sizes are listed in Section 3.1, or you may specify the width and height directly, as described in the same chapter.
A basic text to PDF convertor is included in cpdf. It takes a UTF8 text file (ASCII is a subset of UTF8) and typesets it ragged-right, splitting on whitespace. Both Windows and Unix line endings are allowed.
cpdf -typeset file.txt -create-pdf-papersize a3portrait -font Courier -font-size 10 -o out.pdf
The standard paper sizes are listed in Section 3.1, or you may specify the width and height directly, as described in the same chapter. The standard fonts are listed in chapter 8. The default font is Times-Roman and the default size is 12.
Simple facilities for making PDFs from PNG and JPEG images are included in cpdf. The resulting file can be written out, or used for further operations.
For PNG files, the file must have no transparency and no interlacing, and must not be palletised:
cpdf -png image.png -o out.pdfcpdf image.png AND -add-text "My Image" -o out.pdf
Notice that the -png can be omitted if your file has a standard file extension. Almost any JPEG file may be used with -jpeg or again, with a standard extension:
cpdf -jpeg image.jpg -o out.pdf
The output file will have one point of width or height for each pixel in the input.
Cpdf can build multi-pages files from one or more PDF-appropriate JBIG2 fragments, prepared by the jbig2enc program. In lossless mode, there is one JBIG2 fragment for each page:
cpdf -jbig2 1.jbig2 -jbig2 2.jbig2 -jbig2 3.jbig2 -o out.pdf
This produces a PDF of three pages. In lossy mode, a JBIG2Globals stream can be added, which contains shared data for several pages:
cpdf -jbig2-global 0.jbig2globals -jbig2 1.jbig2 -jbig2 2.jbig2 -jbig2 3.jbig2 -o out.pdf
The -jbig2-global option may be used to change the JBIG2Globals stream in use. The -jbig2-global-clear option may be used to cease use of a globals stream and return to lossless mode.
