IMAQ GetPalette VI

Owning Palette: External DisplayInstalled With: NI Vision Development Module

Selects a display palette. Five predefined palettes are available. To activate a color palette, choose a code for Palette Number and connect the Color Palette output to the input Color Palette of the IMAQ WindDraw VI.

IMAQ GetPalette

Palette Number (gray) gives you a choice of five predefined palettes. You can choose from the following values:

Gray (0)	Grayscale is the default palette. Gradual grayscale variation from black to white. Each value is assigned an equal amount of the RGB intensities.
Binary (1)	Designed especially for binary images. 16 cycles of 16 different colors, where g is the grayscale value and g = 0 corresponds to R = 0, G = 0, B = 0 (black); g = 1 corresponds to R = 1, G = 0, B = 0 (red); g = 2 corresponds to R = 0, G = 1, B = 0 (green); and so on.
Gradient (2)	Gradation from red to white with a prominent range of light blue in the upper range. 0 is black and 255 is white.
Rainbow (3)	Gradation from blue to red with a prominent range of greens in the middle value range. 0 is black and 255 is white.
Temperature (4)	Gradation from light brown to dark brown. 0 is black and 255 is white.

error in (no error) describes the error status before this VI or function runs. The default is no error. If an error occurred before this VI or function runs, the VI or function passes the error in value to error out. This VI or function runs normally only if no error occurred before this VI or function runs. If an error occurs while this VI or function runs, it runs normally and sets its own error status in error out. Use the Simple Error Handler or General Error Handler VIs to display the description of the error code. Use error in and error out to check errors and to specify execution order by wiring error out from one node to error in of the next node.

	status is TRUE (X) if an error occurred before this VI or function ran or FALSE (checkmark) to indicate a warning or that no error occurred before this VI or function ran. The default is FALSE.
	code is the error or warning code. If status is TRUE, code is a nonzero error code. If status is FALSE, code is 0 or a warning code.
	source describes the origin of the error or warning and is, in most cases, the name of the VI or function that produced the error or warning. The default is an empty string.

Color Palette indicates an array of clusters composed of 256 elements for each of the three color planes (red, green, and blue). A specific color is the result of applying a value between 0 and 255 for each of the three color planes. If the three planes have identical values, a gray level is obtained (0 specifies black and 255 specifies white).

Note This output is to be directly connected to the input Color Palette of the IMAQ WindDraw VI.

	Red is the output red value.
	Green is the output green value.
	Blue is the output blue value.

error out contains error information. If error in indicates that an error occurred before this VI or function ran, error out contains the same error information. Otherwise, it describes the error status that this VI or function produces. Right-click the error out indicator on the front panel and select Explain Error from the shortcut menu for more information about the error.

	status is TRUE (X) if an error occurred or FALSE (checkmark) to indicate a warning or that no error occurred.
	code is the error or warning code. If status is TRUE, code is a nonzero error code. If status is FALSE, code is 0 or a warning code.
	source describes the origin of the error or warning and is, in most cases, the name of the VI or function that produced the error or warning. The default is an empty string.
