classRgbImage : Image

RGB image created from raw pixel data.

RgbImage stores image data in RGB or RGBA format. The pixel data is copied when the image is created, so the original buffer can be freed after construction.

Example:

// Create a 2x2 red image (RGB)
ubyte[] pixels = [
   255, 0, 0,  255, 0, 0,  // Row 1: red, red
   255, 0, 0,  255, 0, 0   // Row 2: red, red
];
auto img = new RgbImage(pixels, 2, 2, 3);
assert(img.width == 2);
assert(img.height == 2);
assert(img.depth == 3);

Fields

FltkRgbImage _rgbHandleThe underlying RGB image handle

Methods

FltkRgbImage rgbHandle() @safe nothrow @nogcReturns the underlying RGB image handle.

bool isValid() const @safe nothrow @nogcChecks if this RGB image is valid.

const(ubyte)[] pixels() const nothrow @nogcGets the pixel data as a D slice.

Constructors

this(const(ubyte)[] data, int width, int height, int depth = 3, int lineSize = 0)Creates a new RGB image from pixel data.

Destructors

~thisDestroys the RGB image and releases resources.
