About fontShapesExample

Learning Objectives

This example demonstrates several methods of drawing strings and characters using TrueType font. In this demonstration, text is drawn in the following ways:

• Character drawn as a font bitmap

• Character drawn as a filled vector

• Character drawn as filled polygons

• Character drawn as unfilled polygons

• String drawn as a font bitmap

• String drawn as a filled vector

• String drawn as an unfilled vector

This example covers the following functions:

• ofTrueTypeFont and ofTTFCharacter as data types
• ````drawString()anddrawStringAsShapes()```
• getCharacterAsPoints() and setFilled()
• getOutline() and getVertices() to access polygon information for strings and characters

In the code, pay attention to:

• Note the difference between drawString() which draws a bitmap of the font, and drawStringAsShapes() which draws the font as a vector
• Use of the function font.getCharacterAsPoints() to return the point outline of a character
• Explore drawing characters with and without fill: testChar.setFilled(true) and testChar.setFilled(false)
• Use of ofTTFCharacter.getOutline() to extract polygon outlines from a character
• Use of ofTTFCharacter.getOutline()[i].getVertices() to extract vertices from each [i] polygon outline

Expected Behavior

When launching this app, you should see a white screen with green text displaying a variety of characters and text. The large individual characters should update on key press, and the bottom rows of text should display strings in bitmap and vector.

Instructions for use:

• Type any key to update the displayed character
