D2D1 Bitmap Overview
The D2D1 bitmap is a crucial component of Direct2D graphics. It represents a bitmap data structure used to efficiently store images and draw them on the screen.
D2D1 Bitmap Structure
A D2D1 bitmap is composed of multiple layers, each containing a set of data. The key is the Layer Data, which holds the pixel data and is crucial for rendering.
Each layer contains: Texture - The image texture to be displayed.
Base - Contains the base of the layer. Data - The actual pixel data of the layer.The format ensures a structured and efficient representation of the image data.
D2D1 Bitmap Rendering
Direct2D utilizes the Layer data to determine which pixels to draw on the screen.
The Layer data determines the Texture for each pixel in the bitmap.
D2D1 Bitmap Example
This is a simplified example illustrating the core concept. You'll find more complex examples in the documentation.
The key is that the Layer data defines the rasterization process.
