I tried deleting PageDrawer.showFontGlyph(), but then the project doesn't build
anymore. Wrapping the content of PageDrawer.showFontGlyph() with a try catch
worked perfectly!
@Override
protected void showFontGlyph(Matrix textRenderingMatrix, PDFont font, int
code, String unicode,
Vector displacement) throws IOException
{
try{
AffineTransform at = textRenderingMatrix.createAffineTransform();
at.concatenate(font.getFontMatrix().createAffineTransform());
Glyph2D glyph2D = createGlyph2D(font);
drawGlyph2D(glyph2D, font, code, displacement, at);
}catch (EOFException eofException){
System.err.println(eofException.getMessage());
}
}
Thanks for all the help,
Philippe Fisher
