Creating a PDF File
The eaGeier allows to print its data or to export it via email as PDF file. For both it needs to create a PDF file first.
Creating a PDF file works straightforward following the instructions of the documentation at Apple. Start by opening a new file and start with a page:
UIGraphicsBeginPDFContextToFile(pdfFileName, CGRectZero, nil); UIGraphicsBeginPDFPageWithInfo(CGRectMake(0, 0, 612, 792), nil);
Note that the values 612 x 792 define a page in US letter format. An A4 page needs appropriate adjusting (595.28 x 841.89). The second command is called for every new page you want to add to the file.
To close the PDF file and write it out use
UIGraphicsEndPDFContext();
Filling the PDF files works using CGContext drawing functions.
