DrawPixel method

Syntax

Boolean DrawPixel(nLeft As Number, nTop As Number, nPenColor As Number, nPenOpacity As Number)

Return value

Returns true if the function succeeded.

Parameters

Parameter	Type	Required	Description
nLeft	Number	Yes	Specifies the horizontal coordinate of the pixel.
nTop	Number	Yes	Specifies the vertical coordinate of the pixel.
nPenColor	Number	No	Optional parameter containing a color value. If no color is specified, the current pen color will be used instead.
nPenOpacity	Number	No	Optional parameter containing the opacity percentage (where 0% is completely transparent). If no opacity is specified, the current pen opacity will be used instead.

Example

The example below shows how to use the method. If you take a look at the example code, assume there is a reference to the Marblecore Imaging object with the name 'MarblecoreImaging'. Transparent parts of the image are displayed using a checkerboard pattern.

1 // Creates a new transparent image
2 MarblecoreImaging.Create(150, 150, true);
3 
4 // Execute the operation
5 MarblecoreImaging.DrawPixel(75, 75);
6 
7 // Save the modified image to the specified file
8 MarblecoreImaging.SaveToFile("example-drawpixel.jpg");
