Image Data Exchange and Initialization Functions

Intel® IPP implements image processing functions that perform image data manipulation, exchange and initialization operations. Table "Image Data Exchange and Initialization Functions" lists the functions:

Image Data Exchange and Initialization Functions
Function Base Name	Operation
Convert	Converts pixel values in an image from one bit depth to another
Scale	Scales pixel values of a image and converts them to another bit depth
Set	Sets an array of pixels to a value
Copy	Copies pixel values between two images
CopyConstBorder	Copies pixels values between two images and adds the border pixels with a constant value
CopyReplicateBorder	Copies pixel values between two images and adds the replicated border pixels
CopyWrapBorder	Copies pixel values between two images and adds the border pixels
CopySubpix	Copies pixel values between two images with subpixel precision
CopySubpixIntersect	Copies pixel values of the intersection with specified window with subpixel precision
Dup	Copies gray scale image to all channels of the color image
Transpose	Transpose a source image
SwapChannels	Changes the order of channels of the image
AddRandUniform_Direct	Generates random samples with uniform distribution and adds them to an image data
AddRandGauss_Direct	Generates random samples with Gaussian distribution and adds them to an image data
ImageJaehne	Creates the Jaehne's test image
ImageRamp	Creates the test image that has an intensity ramp
SampleLine	Reads all pixels on the raster line into the buffer
ZigzagFwd8x8	Converts a conventional order to the zigzag sequence
ZigzagInv8x8	Converts a zigzag sequence to the conventional order
ResampleRowGetSize	Computes the sizes of the resample structure and the work buffer
ResampleRowInit	Initializes the row resampling structure
ResampleRowGetBorderWidth	Computes the width of the left and right borders
ResampleRow, ResampleRowReplicateBorder	Perfroms row-oriented resampling of the image

Many solutions and hints for use of these functions can be found in Intel® IPP Samples. See Intel® IPP Image Processing and Media Processing Samples downloadable from http://www.intel.com/cd/software/products/asmo-na/eng/220046.htm.
