I was working on DFT a little earlier and I realized that my bitmap font system wasn't as finished as I thought it was (word-break formatting hadn't been added.) So, I went through and added it and viola, I have a fully functional bitmap font system. It supports a combination of left, center, right, top, vertical center, bottom, and word-break formatting.
Word-break formatting works pretty simply (done behind the scenes.) BitmapFont::FormatString() takes the string as well as a boolean stating whether or not to do word-break formatting and the width of the bounds. It searches through and adds newlines when needed; if a word is too long to fit into the bounds, then "-\n" is used to split it.
Here's a screenshot of the system in action (this also shows the color-formatting in action as well):

For those that are interested, here's my formatting code:
int BitmapFont::FormatString(std::string *Text, bool WordBreak, int BoundsWidth){ if(!Text) return 0; size_t StartingSize = Text->size(); int Width = 0, WidthSinceLastSpace = 0; int LastSpace = 0; for(unsigned int Index = 0; Index < Text->size(); ++Index) { char Character = (*Text)[Index]; switch(Character) { case '\t': { // expand tabs --StartingSize; Text->insert(Index + 1, " "); Text->erase(Index, 1); break; } case ' ': { // store the position of the last space LastSpace = Index; WidthSinceLastSpace = 0; break; } } if(WordBreak) { int CharWidth = Metrics[Character]; if(Width + CharWidth > BoundsWidth) // if we're going to go out of bounds, move to the next line { if(WidthSinceLastSpace < BoundsWidth) // if the word is smaller than the bounds { (*Text)[LastSpace] = '\n'; Width = WidthSinceLastSpace; } else // if the word is larger than the bounds { Text->insert(Index - 1, "-\n"); WidthSinceLastSpace = 0; Width = 0; } } Width += CharWidth; WidthSinceLastSpace += CharWidth; } } return (int)(StartingSize - Text->size());}-edit-
Here's the code for the example:
// ^# is the color formatting tag.// The dft::Graphics::Color::Red at the end is the default color.Tahoma8->PreRender();Tahoma8->Print("This ^1is ^2a ^3test ^4of ^5the ^6bitmap ^7font ^8system^9!!!", -1, 0, 0, dft::Graphics::Color::Red);dft::Rectangle Bounds(dft::Point(100, 100), 100, 300);Tahoma8->Print("This ^1is ^2a ^3test ^4of ^5the ^6bitmap ^7font ^8system^9!!!", -1, &Bounds, dft::Graphics::FontFormatting::Center | dft::Graphics::FontFormatting::VCenter | dft::Graphics::FontFormatting::WordBreak, dft::Graphics::Color::Red);Bounds = dft::Rectangle(dft::Point(300, 100), 100, 300);Tahoma8->Print("This ^1is ^2a ^3test ^4of ^5the ^6bitmap ^7font ^8system^9!!!
