PagesApp not working

[thmarx]

Hi,

I have looked at the demos and there seems to be problems with the PagesApp. Texts are not output to the PDF.

PagesApp does not embed fonts in PDF, so some viewers may not be able to see the text.
For example, the following program embeds fonts:

public class PagesApp {
	public static void main(String[] args) throws Exception {
		try (PDFWriter pdf = new PDFWriterImpl(new FileRandomBuilder(new File("out/pages.pdf")))) {
			pdf.getParams().setVersion(Version.V_PDFA1B);
			
			FontFace fontFace = new FontFace();
			fontFace.src = new FileSource(new File("/usr/share/fonts/truetype/noto/NotoMono-Regular.ttf"));
			fontFace.fontFamily = FontFamilyList.SERIF;
			pdf.getFontManager().addFontFace(fontFace);
			
			try (PDFGraphics2D g2d = new PDFGraphics2D(pdf.nextPage(PDFUtils.mmToPt(PDFUtils.PAPER_A4_WIDTH_MM),
					PDFUtils.mmToPt(PDFUtils.PAPER_A4_HEIGHT_MM)))) {
				g2d.setFont(new Font(Font.SERIF, Font.PLAIN, 38));
				g2d.drawString("Page 1", 10, 100);
			}
			try (PDFGraphics2D g2d = new PDFGraphics2D(pdf.nextPage(PDFUtils.mmToPt(PDFUtils.PAPER_A4_WIDTH_MM),
					PDFUtils.mmToPt(PDFUtils.PAPER_A4_HEIGHT_MM)))) {
				g2d.setFont(new Font(Font.SERIF, Font.PLAIN, 38));
				g2d.drawString("Page 2", 10, 100);
			}
		}
	}
}

Sorry, but that example also doesn't work. At least with both released versions (1.1.0 and 1.2.0), it's not possible to produce a correct pdf.
I tried the DrawApp example, and the created pdf is also not correct. The pages are just empty.
If I open the pdfs with the Acrobat Reader an error message pops up, but without any meaningful details.

I upload both pdfs, maybe it helps analyzing the problem.

Sorry, I cannot reproduce the problem.
The attached project works fine with gradle run.

Crazy, your project produces an empty PDF on my system.
Maybe an issue for Windows systems, or some encoding stuff?

I tested with jdk 17 and 19.

I just tested with JDK17 on Windows and could not reproduce the problem.
Since I cannot reproduce the issue, I'm unable to respond.

That is a pity. But if you can't reproduce the problem, there's probably nothing you can do.
