Requires: NI Vision Development Module
Use the Files VIs to read, write, and retrieve image file information. The file formats NI Vision supports are BMP, TIFF, JPEG, PNG, AIPD (internal file format), and AVI (for multiple images).
| Palette Object | Description |
|---|---|
| IMAQ ReadFile |
Reads an image file. The file format can be a standard format (BMP, TIFF, JPEG, JPEG2000, PNG, and AIPD) or a nonstandard format known to the user. |
| IMAQ Write File 2 |
Writes the image to a file in the selected format. |
| IMAQ Read Image And Vision Info |
Reads an image file, including any extra vision information saved with the image. This includes overlay information, pattern matching template information, calibration information, and custom data, as written by the IMAQ Write Image And Vision Info File 2 instance of the IMAQ Write File 2 VI. |
| IMAQ Write String |
Returns a string that contains the entire contents of the image encoded as an image file. The string can be saved to file, or, for example, transferred to a remote computer using FTP. |
| IMAQ GetFileInfo |
Obtains information regarding the contents of the file. This information is supplied for standard file formats only: BMP, TIFF, JPEG, JPEG2000, PNG, or AIPD. |
| IMAQ Load Image Dialog |
Displays a dialog box with which you can specify a path or paths to images. This dialog box is similar to the LabVIEW File Dialog primitive, but it provides a preview of the image files selected and defaults to showing only supported image types. |
| Subpalette | Description |
|---|---|
| AVI |
Use the AVI VIs to read and write multiple images to an AVI file. |
