Owning Palette: Picture Functions VIs
Requires: Base Development System
Draws a patterned rectangle in the specified picture to create the effect of graying-out a section of the picture.
An underlying picture shows through the holes in the pattern. The VI does not frame the rectangle.
|picture is the picture to which you want to add the rectangle. The default is an empty picture.|
|rect is a cluster that contains four numeric controls that describe the left, top, right, and bottom coordinates of the outer edges of the rectangle. Horizontal coordinates increase to the right, and vertical coordinates increase to the bottom. |
|color is the color of the pattern. In black and white, the VI uses white. You can wire a color box constant to this input.|
|new picture is the picture that contains the new image. You can wire this output to any other picture input to add more drawing instructions to the picture. You also can wire this output to the Picture to Pixmap VI to obtain an image data cluster. You then can use the Graphics Formats VIs to save the image data to a file. You can wire this output to the Concatenate Strings function to concatenate the output from multiple Picture Functions VIs so that they draw on a single picture control.|
