Draws a rectangle in an Image control.
Linux Caution: A specific configuration is required to use this function in Linux. For more details, see The drawings.
Example
// Draw a rectangle whose background changes from red to blue
// via yellow
IMG_Image1.DrawRectangleGradient(10, 20, 100, 150, LightRed, LightBlue, 0, LightYellow, 30)
Syntax

Drawing a rectangle by specifying the points of the rectangle and the gradient Hide the details

<Image variable>.DrawRectangleGradient(<X1> , <Y1> , <X2> , <Y2> , <Start color> , <End color> [, <Angle> [, <Color 3> [, <Distance color 3> [, <Color 4> [, <Distance color 4>]]]]])
<Image variable>: Image variable
Name of the Image control to be used.
<X1>: Integer
X-coordinate (in pixels) of the upper-left corner of the rectangle.
<Y1>: Integer
Y-coordinate (in pixels) of the upper-left corner of the rectangle.
<X2>: Integer
X-coordinate (in pixels) of the lower-right corner of the rectangle.
<Y2>: Integer
Y-coordinate (in pixels) of the lower-right corner of the rectangle.
<Start color>: Integer or constant
Start color of the gradient. This color can correspond to:
<End color>: Integer or constant
End color of the gradient. This color can correspond to:
<Angle>: Optional integer
Angle that will be used for the selection of colors in the gradient. The angle value is included between 0 (horizontal angle, default value) and 360°.
AndroidJava Only the following angles can be used: 0,90,180,270,360.
<Color 3>: Optional constant or integer
Color that will be used in the gradient. This color can correspond to:
AndroidJava This parameter is not available.
<Distance color 3>: Optional integer
Percentage separating the start color from color 3.
AndroidJava This parameter is not available.
<Color 4>: Optional constant or integer
Color that will be used in the gradient. This color can correspond to:
AndroidJava This parameter is not available.
<Distance color 4>: Optional integer
Percentage separating the start color from color 4.
AndroidJava This parameter is not available.

Remarks

Gradient parameters

The color parameters are used as follows:
The angle is used to define the orientation of the gradient.
Gradients with 3 or 4 colors are only available for 0 or 90 degree angles.
Remark: The gradient colors are not available for some systems (Windows 98 or Me for example) or for TSE 256 colors. In this case, a rectangle whose color corresponds to <Start color> is displayed.
