Class TextObject

java.lang.Object

com.iragui.objects.GUIObject

com.iragui.objects.TextObject

public class TextObject
extends GUIObject

A GUI object that renders text as a texture and displays it in OpenGL.

This class creates a BufferedImage, rasterizes the text with a given Font, Color, and background, and uploads it as an OpenGL texture. The text can be updated dynamically, and it will automatically regenerate the texture when changed.

Features include:

• Support for anti-aliased text rendering
• Support for both RGB and RGBA textures
• Automatic recalculation of text width when the string changes
• Ability to revert to the original text
