Image Class

Package: GHIElectronics.Endpoint.Drawing
Namespace: GHIElectronics.Endpoint.Drawing

A decoded image, ready to blit into a Canvas. Decoding (JPEG / PNG / BMP / GIF / TGA, picked from the file's magic bytes) happens once at Load; Canvas.DrawImage(Image, int, int) then blits + converts to whatever PixelFormat the target canvas uses. The same Image instance is reusable across multiple canvases and multiple frames.

public sealed class Image

Example​

var bytes = ... // load the resource stream
var background = Image.Load(bytes);  // decode once

while (running) {
    canvas.DrawImage(background, 0, 0);  // many frames, no re-decode
    display.Flush(canvas.Buffer);
}

Properties​

Height​

public int Height { get; }

Height in pixels.

Returns int

PixelFormat​

public PixelFormat PixelFormat { get; }

Internal storage format of the decoded pixels. Currently always PixelFormat.Rgb888, the decoder's native output. This does NOT dictate the canvas format; Canvas.DrawImage converts to the target canvas's PixelFormat on draw.

Returns PixelFormat

Width​

public int Width { get; }

Width in pixels.

Returns int

Methods​

Load(byte[] fileBytes)​

public static Image Load(byte[] fileBytes)

Decodes an image file (JPEG / PNG / BMP / GIF / TGA, detected from the file's magic bytes) into an in-memory bitmap.

Returns Image
