The OP seems not interested in how the PDF *looks* at all; rather, what it *means*. Disclaimer: I am not an expert on the PDF format so the below may not be completely accurate. Take it as a simplified description. Disclaimer #2: I have not verified the original claim of what appears on output. A PDF page is, essentially, a list of instructions of the form “at position (X, Y), using the font F, render the string S”. On input, the OP is feeding a text file with lots of blank lines and spaces used for layout. On output, the PDF seems to only contain instructions to render the non-blank lines. pdftotext(1) without the -layout option simply outputs the text from the instructions present in the PDF. (pdftotext -layout interprets the instructions and attempts to reconstruct page layout based on positions.) For a sighted person, there is no difference in appearance between this PDF: At 0 inches down, 0 inches across, render "alma" At 4.667 inches down, 3.1 inches across, render "1" and this PDF: At 0 inches down, 0 inches across, render "alma" At 0.167 inches down, 0 inches across, render "" At 0.333 inches down, 0 inches across, render "" … At 4.5 inches down, 0 inches across render, "" At 4.667 inches down, 0 inches across render "<31 spaces>1" For a blind user and/or a third-party tool aimed at blind users, there seems to be. _______________________________________________ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org https://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
