'Declaration

 

Public Function ARGBI( _

   ByVal Alpha As Byte, _

   ByVal Red As Byte, _

   ByVal Green As Byte, _

   ByVal Blue As Byte _

) As Integer

public int ARGBI( 

   byte Alpha,

   byte Red,

   byte Green,

   byte Blue

)

public function ARGBI( 

    Alpha: Byte;

    Red: Byte;

    Green: Byte;

    Blue: Byte

): Integer;

public function ARGBI( 

   Alpha : byte,

   Red : byte,

   Green : byte,

   Blue : byte

) : int;

public: int ARGBI( 

   byte Alpha,

   byte Red,

   byte Green,

   byte Blue

)

public:

int ARGBI( 

   byte Alpha,

   byte Red,

   byte Green,

   byte Blue

)

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);

}
