imaqSimpleDistance
Usage
int imaqSimpleDistance(Image* dest, Image* source, const StructuringElement* structuringElement);
Purpose
Creates a distance map. The function encodes a particle pixel value as a function of the distance of the pixel from the particle border. For a more precise but slower algorithm, use imaqDanielssonDistance().
Image Types Supported
IMAQ_IMAGE_U8

Type

Description
|
|---|---|---|
| dest | Image* | The destination image. |
| source | Image* | The image that the function uses to compute the distance map. The function modifies the border of the source image. The border must be at least half as large as the larger of the structuring element dimensions. |
| structuringElement | const StructuringElement* | The structuring element used in the operation. Set this parameter to NULL if you do not want a custom structuring element. |
Return Value

Description |
|---|---|
| int | On success, this function returns a non-zero value. On failure, this function returns 0. To get extended error information, call imaqGetLastError(). |
Parameter Discussion
source—This function modifies the source image. If you need the original image, create a copy of the image using imaqDuplicate() before using this function.
