How to create a PDF with a Cartesian grid?

Tags: graphics statePDF syntaxiText 7

Could anyone please provide me a sample program that can dynamically create a grid or even dots starting at (0,0) at bottom left corner on a PDF of page size "Letter"? (max X = 8.5 Inches; max Y = 11 Inches)

Please take a look at the Grid example. Let's write the loops that draw the grid:

PdfCanvas canvas = new PdfCanvas(pdfDoc.addNewPage());
for (float x = 0; x < pageSize.getWidth(); ) {
    for (float y = 0; y < pageSize.getHeight(); ) {
        canvas.circle(x, y, 1f);
        y += 72f;
    }
    x += 72f;
}
canvas.fill();

Here we use pageSize variable to learn the width and the height of the PDF file and just increment x and y with 72 user units (this means that the distance between the dots will be 1 inch).
