Parameters

ImageID: GdPicture image identifier.
Text: Text to draw.
DstLeft: Specifies the x-coordinate of the upper-left corner of the rectangle that bounds the.
DstTop: Specifies the y-coordinate of the upper-left corner of the rectangle that bounds the.
StartColor: Starting color of the gradient. A suitable color value can be obtained by using the ARGBI() method.
EndColor: Ending color of the gradient. A suitable color value can be obtained by using the ARGBI() method.
FontSize: The font size in units specified by the FontSetUnit() method.
FontStyle: A member of the FontStyle enumeration.
FontName: The name of the font. IE: "Arial".
AntiAlias: Set to True to apply the Antialiasing algorithm else False.

Return Value

A member of the GdPictureStatus enumeration.

Remarks

To draw watermark text use an ARGB value with alpha component < 255.

This method requires the Image Documents component to run.

Example

Drawing text using linear gradient fill with red start color and black end color on a jpeg image.

using (GdPictureImaging gdpictureImaging = new GdPictureImaging())

{

    int imageID = gdpictureImaging.CreateGdPictureImageFromFile("input.jpg");

 

    // Draw the text in the top left corner of the image.

    gdpictureImaging.DrawTextGradient(imageID, "GdPicture.Net", 5, 5, gdpictureImaging.ARGBI(255, 255, 0, 0), gdpictureImaging.ARGBI(255, 0, 0, 0), 48, GdPicture14.FontStyle.FontStyleRegular, "Arial", true);

    gdpictureImaging.SaveAsJPEG(imageID, "output.jpg");

    gdpictureImaging.ReleaseGdPictureImage(imageID);

}
