Parameters
- pImage
- Pointer to the ROI in the source and destination image (in-place operation).
- imageStep
- Distance in bytes between starts of consecutive lines in the image buffer.
- roiSize
- Size of the image ROI in pixels.
- seed
- Initial point.
- minDelta
- Minimum difference between neighbor pixels for one-channel data.
- maxDelta
- Maximum difference between neighbor pixels for one-channel data.
- newVal
- Value to fill with for one-channel data.
- pMinDelta
- Pointer to the minimum differences between neighbor pixels for three-channel images.
- pMaxDelta
- Pointer to the maximum differences between neighbor pixels for three-channel images.
- pNewVal
- Pointer to the vector containing values to fill with for three-channel data.
- pRegion
- Pointer to the connected components structure that stores information about the refilled area.
- pBuffer
- Pointer to the temporary buffer.
Description
This function operates with ROI (see Regions of Interest in Intel IPP).
This function performs flood filling of the group of connected pixels in the
seed
pixel neighborhoods whose pixel values v
satisfy the following conditions:

where
v
0
is the pixel value of the seed
point, and d
lw
, d
up
are minDelta
, maxDelta
, respectively. Values of these pixels are set to the newVal
value.The function requires a temporary buffer whose size should be computed with the function
ippiFloodFillGetSize_Grad
beforehand.The functions with the “
_4con
” suffixes check 4-connected neighborhood of each pixel, i.e., side neighbors. The functions with the “_8con
” suffixes check 8-connected neighborhood of each pixel, i.e., side and corner neighbors. See Figure Pixels Connectivity Patterns”
.Return Values
- ippStsNoErr
- Indicates no error. Any other value indicates an error or a warning.
- ippStsNullPtrErr
- Indicates an error condition if one of the specified pointers isNULL.
- ippStsSizeErr
- Indicates an error condition ifroiSizehas a field with zero or negative value.
- ippStsStepErr
- Indicates an error condition ifimageStepis less thanpRoiSize.width*<pixelSize>.
- ippStsNotEvenStepErr
- Indicates an error condition if steps for floating-point images are not divisible by 4, or steps for 16-bit integer images are not divisible by 2.
- ippStsOutOfRangeErr
- Indicates an error condition if theseedpoint is out of ROI.
