IMAQ Create VI
Owning Palette: Image ManagementInstalled With: NI Vision Development ModuleCreates a temporary memory location for an image. Use IMAQ Create in conjunction with the IMAQ Dispose VI to create or dispose of NI 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.

Image Name is the name associated with the created image. Each image created must have a unique name. |

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.

Image Type specifies the image type. Choose from the following values:

New Image is the Image reference that is supplied as input to all subsequent (downstream) functions used by NI Vision. Multiple images can be created in a LabVIEW application. |

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.
