Parameters

Alpha: The value for the alpha component also known as a transparency. Use the value between 0 (full transparency) and 255 (full opacity).
Red: The value for the red component. Use the value between 0 and 255.
Green: The value for the green component. Use the value between 0 and 255.
Blue: The value for the blue component. Use the value between 0 and 255.

Return Value

A 32-bit value representing a required color.

Example

Rendering an image with a circle onto the background image and saving the result into a png file.

using (GdPictureImaging gdpictureImaging = new GdPictureImaging())
{
    int backColor = gdpictureImaging.ARGBI(255, 0, 255, 0); // Green color
    int circleColor = gdpictureImaging.ARGBI(255, 255, 0, 0); // Red color
 
    // Create a background image.
    int backImage = gdpictureImaging.CreateNewGdPictureImage(320, 200, 32, backColor);
 
    // Create an image used for drawing, and draw a circle on it.
    int circleImage = gdpictureImaging.CreateNewGdPictureImage(80, 80, 32, gdpictureImaging.ARGBI(0, 0, 0, 0));
    gdpictureImaging.DrawFilledCircle(circleImage, 40, 40, 60, circleColor, false);
 
    // Draw an image with a circle onto the background image.
    gdpictureImaging.DrawGdPictureImage(circleImage, backImage, 0, 0, 80, 80, System.Drawing.Drawing2D.InterpolationMode.Default);
    gdpictureImaging.SaveAsPNG(backImage, "output.png");
 
    // Release used resources.
    gdpictureImaging.ReleaseGdPictureImage(circleImage);
    gdpictureImaging.ReleaseGdPictureImage(backImage);
}

Example

Rendering an image with a circle onto the background image and saving the result into a png file. using (GdPictureImaging gdpictureImaging = new GdPictureImaging()) { int backColor = gdpictureImaging.ARGBI(255, 0, 255, 0); // Green color int circleColor = gdpictureImaging.ARGBI(255, 255, 0, 0); // Red color // Create a background image. int backImage = gdpictureImaging.CreateNewGdPictureImage(320, 200, 32, backColor); // Create an image used for drawing, and draw a circle on it. int circleImage = gdpictureImaging.CreateNewGdPictureImage(80, 80, 32, gdpictureImaging.ARGBI(0, 0, 0, 0)); gdpictureImaging.DrawFilledCircle(circleImage, 40, 40, 60, circleColor, false); // Draw an image with a circle onto the background image. gdpictureImaging.DrawGdPictureImage(circleImage, backImage, 0, 0, 80, 80, System.Drawing.Drawing2D.InterpolationMode.Default); gdpictureImaging.SaveAsPNG(backImage, "output.png"); // Release used resources. gdpictureImaging.ReleaseGdPictureImage(circleImage); gdpictureImaging.ReleaseGdPictureImage(backImage); }
