Read TutorialKey GDI+ Concepts
GDI+ provides a rich set of objects and methods for creating advanced 2D graphics. Key components include:
- Graphics Objects: Represent the drawing surface and provide methods for drawing.
- Pens: Used to draw lines and outlines of shapes.
- Brushes: Used to fill areas and shapes with colors, patterns, or gradients.
- Colors: Define the color values used by pens and brushes.
- Fonts: Specify the typeface, size, and style for rendering text.
- Images: Represent raster graphics that can be loaded, manipulated, and saved.
Example: Drawing a Red Line
Here's a simple C++ code snippet demonstrating how to draw a red line:
#include <windows.h>
#include <gdiplus.h>
using namespace Gdiplus;
// ... inside your window procedure or drawing function ...
Graphics graphics(hdc); // hdc is your device context handle
Pen redPen(Color(255, 255, 0, 0), 2); // Alpha, Red, Green, Blue, Width
graphics.DrawLine(&redPen, 50, 50, 200, 100);
