Post subject:  Fonts, Colors and Multiple Uses
At the top of my document I have three Font's defined like this:

Code:
private Font headerFont = new Font("Arial", 13);
private Font titleFont = new Font("Clarendon", 20);
private Font normalFont = new Font("Arial", 10);


Then, at the beginning of a function I set their colors like this:

Code:
normalFont.Color = Colors.Black;
normalFont.Bold = false;
titleFont.Color = Color.Parse("0x43545E");
titleFont.Bold = true;
headerFont.Color = Color.Parse("0x43545E");
headerFont.Bold = true;


During the creation of my document, I do many calls like this (txtFr is a textframe):

Code:
var p = txtFr.AddParagraph("Header");
p.Format.Font = headerFont.Clone();

p = txtFr.AddParagraph("Content");
p.AddLineBreak();
p.AddLineBreak();
p.Format.Font = normalFont.Clone();

p = txtFr.AddParagraph("Another Title");
p.Format.Font = titleFont.Clone();


Anything that I set to normalFont seems to be working just fine.

The first time I use headerFont it works fine. Second (third, fourth, etc) time I use headerfont, the text is output correctly, but seems to be set to white (on a white background). Am I missing something here?

Cheers

Hi!

We never use MigraDoc this way. Maybe something goes wrong in the "Clone()" calls.

We would define Styles with the different colors and font styles. Then we'd just set the Style of the paragraphs.

See the file Styles.cs in the HelloMigraDoc sample for recommended usage.

Thanks for the idea, Thomas. I still seem to be having the same problem, though.

Here's the code now:

Code:
            //set the standard font
            var style = document.Styles["Normal"];
            style.Font.Name = "Arial";
            style.Font.Size = 10;
            style.Font.Color = Colors.Black;
            style.Font.Bold = false;

            //set the title font
            style = document.Styles["Heading1"];
            style.Font.Name = "Clarendon";
            style.Font.Size = 20;
            style.Font.Color = Color.Parse("0x43545E");
            style.Font.Bold = true;

            //set the heading font
            style = document.Styles["Heading2"];
            style.Font.Name = "Arial";
            style.Font.Size = 13;
            style.Font.Color = Color.Parse("0x43545E");
            style.Font.Bold = true;

            p = txtFr.AddParagraph("heading here");
            p.Style = "Heading2";
           
            p = txtFr.AddParagraph("normal text here");
            p.AddLineBreak();
            p.AddLineBreak();
            p.Style = "Normal";

            p = txtFr.AddParagraph("heading2");
            p.Style = "Heading2";


The "heading2" looks to be rendered (I can cut and paste it), but it appears to white text on white background.

This seems to be an issue with Color.Parse(). I've switched this:
style.Font.Color = Color.Parse("0x43545E");
For this:
style.Font.Color = Color.FromRgbColor((byte)255, Color.Parse("0x43545E"));

And now it works just fine! Weird.

This should also work: style.Font.Color = Color.Parse("0xFF43545E");

Your text probably wasn't white, it was transparent. This makes a difference when you activate the transparency grid in Adobe Reader.
I should have checked the Color.Parse source code last week. :oops:

So your original code should work - but using styles is better when the document grows (and you can add own styles when needed).
