Data Fields
int	w

	Image height in pixels (must be > 0).
rgb_pixel_t *	pixels
	Pixel data array (width * height RGB pixels, row-major order).

Detailed Description

SIMD-friendly storage for one RGB pixel. r, g, and b hold the color channels and padding keeps the layout aligned for vector loads; it is normally embedded in renderer buffers, not individually allocated.

An owned RGB image with dimensions and row-major pixel storage

Complete image structure containing dimensions and pixel data. Pixel data is stored as a contiguous array of RGB pixels in row-major order. Compatible with webcam capture and image processing pipeline.

MEMORY LAYOUT:

• structure and pixels share one allocation, with pixels aligned to 64 bytes
• pixels array size: width * height * sizeof(rgb_pixel_t)
• Pixel access: pixels[row * width + col]
• Row-major order (first row, then second row, etc.)

Note

Pixel array must be allocated (by image_new()).

Only image_destroy() releases an owned image; pixels are a borrowed view.

Compatible with webcam capture functions (webcam_read_context()).
