Storing a PdfContentByte state ?
Is it possible to store the configuration of a PdfContentByte so that
the currently selected font and size (amongst other things) is
preserved, I'm thinking the whole state from the iText side. This
allows the programmer to run a sub-method which can reconfigure the
entire PdfContentByte to do its work and then restore the state before
it return. The most common problem for me is selecting another font
with cb.setFontAndSize();
There is PdfContentByte.saveState() (which I presume is used for
PostScript "savestate") which is good to revert back to previous matrix
translation, this is in relation to PostScript graphics state so works
within the PDF language.
Does the same exist for the PdfContextByte context within the API. This
would be implemented on the iText library side, rather than something
which would be translated into PS the PDF.
Feel free the point out if my design pattern is a bad idea and I have
incorrect thinking.
PdfContentByte.saveContentByte(); // stacking recursive state push
PdfContentByte.restoreContentByte(); // stacking recursive state pop
PdfContentByte.loadContentByte(PdfContentByteConfig
pdfContentByteConfig); // overwrite current
PdfContentByteConfig pdfContentByteConfig =
PdfContentByte.saveContentByte(); // get copy of current
