ImageToDvrSGL_2D
OpenLvVision_Image.lvlib:DataAccess.lvlib:ImageToDvrSGL_2D.vi
Returns a DVR (Data Value Reference) to the image data, allowing direct manipulation without copying.
Delete the DVR after use.
| error in error in can accept error information wired from VIs previously called. Use this information to decide if any functionality should be bypassed in the event of errors from other VIs. Right-click the error in control on the front panel and select Explain Error or Explain Warning from the shortcut menu for more information about the error. |
| status status is TRUE (X) if an error occurred or FALSE (checkmark) to indicate a warning or that no error occurred. Right-click the error in control on the front panel and select Explain Error or Explain Warning from the shortcut menu for more information about the error. |
| code |
| source source describes the origin of the error or warning. Right-click the error in control on the front panel and select Explain Error or Explain Warning from the shortcut menu for more information about the error. |
| Optional Rectangle Rectangle to extract the data. |
| Left X-coordinate of the left edge pixel. |
| Top Y-coordinate of the top edge pixel. |
| Right X-coordinate of the right edge pixel. |
| Bottom Y-coordinate of the bottom edge pixel. |
| Image Reference In An Image reference is a handle to the actual image data in memory. It's important to note that you are responsible for manually releasing (deallocating) the memory associated with this image reference when it's no longer needed to prevent memory leaks. |
| Include Border Include Border Pixels: Set to TRUE to include border pixels from the Optional Rectangle in the output array (default: FALSE). |
| Step Sizes |
| X Step Size Horizontal sampling step defining which rows from the source image are included in the data array (vertical reduction). A value of 2 includes every second row; 1 includes all rows. |
| Y Step Size Vertical sampling step defining which columns from the source image are included in the data array (horizontal reduction). A value of 3 includes every third column; 1 includes all columns. |

| Line Info |
| Total Width Nmber of elements in the data array representing one image line. For 2D/3D arrays, it's the size of the second dimension. For 1D arrays, it's the length of a line segment. Incrementing the array offset by Total Width moves to the next line. |
| Left Border Number of array elements representing the left border for each image line. |
| Image Data Number of array elements containing the actual image data for each line within the optional rectangle. |
| Right Border Number of array elements representing the right border for each image line. |
| Padding Number of array elements representing the end-of-line alignment padding. |
| EDVR 2D SGL EDVR 2D SGL is an external data value reference array which refers to the requested pixels of the source Image. |
