Image Vision Data Access functions
This topic lists the Vision Data Access functions that reference an Image data structure as the first parameter.
| Function Functions are tools that are available in Spreadsheet for processing and analyzing acquisitions or other results. You can add functions to your Spreadsheet job to create tool chains and produce results for specific applications. | Description |
|---|---|
|
GetArea(Image, [Index]) |
Returns the number of pixels processed in an area. The Image structure must be created by a FindCircleDefects function. |
|
GetBrightPixelCount(Image) |
Returns the number of pixels above the threshold. The Image structure must be created by a FindCircleDefects function. |
|
GetDarkPixelCount(Image) |
Returns the number of pixels below the threshold. The Image structure must be created by a FindCircleDefects function. |
|
GetHeight(Image, [Index]) |
Returns a height value in pixels. |
| GetImageBufferCount(Event) | Returns the number of image buffers used. |
| GetImageFileName(Image) |
Returns the file name of the current image. Note: This function must reference the
|
| GetImageOverrunBufferCount(Event) | Returns the number of acquisitions lost due to lack of image buffers. This count is reset when the vision system goes Online or Offline, or after the LineScanStatReset function is executed. |
|
GetPixelValue(Image, Fixture A fixture is a coordinate location on the image that keeps the tool in the place determined by the fixture., Point) |
Returns the greyscale value, between 0-255, at a specified point in an image. |
|
GetRegion(Image) |
Returns a Region data structure that contains the region coordinates of the referenced Image function. The output can be used as an External Region parameter reference for Vision Tools that support the External Region parameter. |
| GetStitchComplete(Image) | Returns the completion status of the stitching operation, 1 for true and 0 for false. |
|
GetString(Image) |
Returns the string sent to an In-Sight secondary device when it receives a network trigger from an In-Sight primary device. The default
Image data structure in cell |
|
GetThresh(Image) |
Returns the current binary threshold value. The GetThresh function must reference an Image data structure created by either the Filter function. The Filter Type must be set to Binarize, Greyscale Distance or Sharpen. |
|
GetWidth(Image, [Index]) |
Returns a width value in pixels. |
|
GetX(Image, [Index1], [Index2]) |
Returns the X-coordinate. |
|
GetY(Image, Index) |
Returns the Y-coordinate. |
