image data image data returns information about the image so you can use the Draw Flattened Pixmap VI to draw it as a picture.

• image type image type is reserved for future use.

  image depth image depth specifies the color depth of the image, which is the number of bits to use to describe the color of each pixel in the image. Valid values include 1, 4, 8, and 24 bits per pixel.

  image image is an array of bytes that describes the color of each pixel in the image in raster order. The value of image depth determines how LabVIEW interprets the value of this output.

  • image is an array of bytes that describes the color of each pixel in the image in raster order. The value of image depth determines how LabVIEW interprets the value of this output.

• mask mask is an array of bytes in which each bit describes mask information for a pixel. The first byte describes the first eight pixels, the second byte describes the next eight pixels, and so on.

  • mask is an array of bytes in which each bit describes mask information for a pixel. The first byte describes the first eight pixels, the second byte describes the next eight pixels, and so on.

• colors colors is an array of RGB color values that correspond to the values in image. The value of image depth determines how LabVIEW interprets the value of this output.

  • colors is an array of RGB color values that correspond to the values in image. The value of image depth determines how LabVIEW interprets the value of this output.

• Rectangle Rectangle is a cluster that contains coordinates that describe the bounding rectangle of the image.

  • left left is the horizontal coordinate of the left edge of the rectangle.

    top top is the vertical coordinate of the top edge of the rectangle.

    right right is the horizontal coordinate of the right edge of the rectangle.

    bottom bottom is the vertical coordinate of the bottom edge of the rectangle.
