Owning Palette: Graphics & Sound VIs

Use the Picture Functions VIs to create visual representations of data. Many of these picture VIs use clusters to define points and rectangles. The VIs related to drawing text use clusters and enumerations to describe the font choice and the positioning of the text.

Palette Object	Description
Color Box Constant	Use the color box constant to supply a constant color value to the block diagram.
Color to RGB	Resolves any color input, including system colors, into its respective red, green, and blue components.
Create Mask	Applies a mask to an image and returns the mask information in the mask element of image data. This VI is useful if you want to make a certain color in an image transparent before writing the image to a picture indicator.
Draw Arc	Draws an arc in a picture.
Draw Circle by Radius	Draws a circle based on a specified radius and center point.
Draw Flattened Pixmap	Draws a 1-, 4-, or 8-bit pixmap or a 24-bit RGB pixmap into a picture.
Draw Grayed Out Rect	Draws a patterned rectangle in the specified picture to create the effect of graying-out a section of the picture.
Draw Line	Draws a line from the current pen position to the specified location in a picture.
Draw Multiple Lines	Draws multiple connected lines into a picture.
Draw Oval	Draws an oval in the rectangle you specify, optionally filling the interior.
Draw Point	Sets a pixel in a picture to a specified color.
Draw Rect	Draws a rectangle, optionally filling the interior.
Draw Round Rect	Draws a rounded rectangle into a picture.
Draw Text at Point	Draws a string into a picture.
Draw Text in Rect	Draws a string into a picture.
Draw Unflattened Pixmap	Converts a pixmap into a picture so you can use other Picture Functions VIs to append drawing instructions to the image. The data type you wire to the data input determines the polymorphic instance to use. If you want to convert a 4-bit or 8-bit pixmap, you must manually select the polymorphic instance you want to use.
Empty Picture	Returns an empty picture. The picture input for all Picture VIs is an empty picture by default.
Get Image Subset	Returns a subset of a source image instead of the entire image. Use the Picture to Pixmap VI to convert a picture to a cluster you can wire to image data.
Get Text Rect	Returns the bounding rectangle of a string.
Hilite Color	Returns two new colors well matched to the input color for highlight and shadow coloration, based on the input color and a percentage you specify.
Move Pen	Changes the current pen location of a picture to the specified position or by the specified amount if the position is relative.
Picture to Pixmap	Converts a picture to a cluster of image data you can use to perform certain tasks with the image, such as save it to a file using the Graphics Formats VIs.
RGB to Color	Converts a red, green, and blue value from 0 to 255 to the corresponding RGB color.
