IMAQ Create

Creates an image.

Note  Use IMAQ Create in conjunction with IMAQ Dispose to create/dispose of IMAQ Vision images in LabVIEW.
Border Size determines the width, in pixels, of the border to create around an image. These pixels are used only for specific VIs. Create a border at the beginning of your application if an image is to be processed later using functions that require a border (for example, labeling and morphology). The default border value is 3. With a border of three pixels, you can use kernels up to 7 × 7 with no change. If you plan to use kernels larger than 7 × 7 in your process, specify a larger border when creating your image.

The following graphic illustrates an 8 × 6 image with a border equal to 0.

In the following 8 × 6 image, the border equals 2, allowing the use of kernels up to 5 × 5.

Note  The border of an image is taken into account only when the image is processed. It is never displayed or stored to a file.
Image Name is the name associated with the created image. Each image created must have a unique name.
error in (no error) is a cluster that describes the error status before this VI executes. Refer to IMAQ VI Error Clusters for more information about this indicator.
Image Type specifies the image type. This input can accept the following values:
8 bits 8 bits per pixel (unsigned, standard monochrome)
16 bits 16 bits per pixel (signed)
float 32 bits (floating point) per pixel
complex 2 × 32 bits (floating point) per pixel (native format after an FFT)
RGB 32 bits per pixel (RGB, color)
HSL 32 bits per pixel (HSL, color)
New Image is the Image structure that is supplied as input to all subsequent (downstream) functions used by IMAQ Vision. Multiple images can be created in a LabVIEW application.
error out is a cluster that describes the error status after this VI executes. Refer to IMAQ VI Error Clusters for more information about this indicator.
