Windows API Reference - Graphics Documentation

Overview

This document provides a comprehensive overview of the Windows API references related to graphics. It covers core functionalities, crucial classes, and best practices for creating visual content.

Core Classes

We'll briefly examine key classes like `Graphics`, `GraphicsPipeline`, and `Screen`. Detailed documentation is available in the linked files.

- **Graphics:** The base class for all graphics-related functionality. - **GraphicsPipeline:** Responsible for managing the rendering process. - **Screen:** Handles the display of graphics on a screen (e.g., a window).

Key Functions

Here's a brief look at some fundamental functions:

SetColor(Color color): Sets the color of a given pixel.
SetPixel(x, y): Sets the pixel at coordinates (x, y) to a given color.
DrawRectangle(x, y, width, height): Draws a rectangle at the specified coordinates.
DrawLine(x1, y1, x2, y2): Draws a line between two points.
GetPixel(x, y): Retrieves the color at a given pixel.

Visual Examples

Let's look at a simple example to demonstrate a few functions:

Example 1: Drawing a Rectangle

This example demonstrates drawing a rectangle to show a fundamental function.


                    int x = 50;
                    int y = 50;
                    int width = 100;
                    int height = 50;

                    Graphics g;
                    g.SetColor(Color.RED);
                    g.SetPixel(x, y, width, height);
                    g.DrawRectangle(g);

This code will draw a red rectangle with coordinates (50, 50) and dimensions of 100x50.

Example 2: Drawing a Line

Demonstrates drawing a line between two points.


                    int x1 = 10;
                    int y1 = 20;
                    int x2 = 15;
                    int y2 = 25;

                    Graphics g;
                    g.SetColor(Color.BLUE);
                    g.DrawLine(x1, y1, x2, y2);

This code will draw a blue line from (10, 20) to (15, 25).
