Is there a way to set font weight in iTextSharp as a number? Now I can set bold font like this:
iTextSharp.text.Font font_main = new iTextSharp.text.Font(someBaseFont, 12, iTextSharp.text.Font.BOLD);
font_main.weight = 600;Is this possible?
When you pick a font family, for instance Arial, you also need to pick a font,
e.g. Arial regular (
arial.ttf), Arial Bold (
arialbd.ttf), Arial Italic (
Arial Bold-Italic (
When you switch styles the way you do in your code snippet, iText switches fonts. In other words: you don't use Arial regular to which you apply a style, you switch to another font in the same family: Arial Bold.
A font program such as the one stored in
contains the instructions to draw the outlines (aka path) of a series of glyphs.
These glyphs are rendered by filling the path using a fill color.
Knowing this is important to achieve your requirement.
You can control the boldness of your font by changing the line-width render-mode. This is especially useful in case you are working with a font family for which there is no bold version of the font available.
iText 7â€™s Text object has a method called
setTextRenderingMode() that is demonstrated in the SayPeace example:
PdfFont font = PdfFontFactory.createFont("c:/windows/fonts/verdana.ttf", PdfEncodings.IDENTITY_H, true); Text bold = new Text("Bold") .setFont(font) .setTextRenderingMode(PdfCanvasConstants.TextRenderingMode.FILL_STROKE) .setStrokeWidth(0.5f) .setStrokeColor(DeviceGray.BLACK); Paragraph p = new Paragraph(bold);
It tells the
Text that the glyphs should be filled (as usual) and stroked (not usual). The strokes should have a width of
0.5 user units (change this to get a different boldness).
