Detailed Description

The IplImage is taken from the Intel Image Processing Library, in which the format is native. OpenCV only supports a subset of possible IplImage formats, as outlined in the parameter list above.

In addition to the above restrictions, OpenCV handles ROIs differently. OpenCV functions require that the image size or ROI size of all source and destination images match exactly. On the other hand, the Intel Image Processing Library processes the area of intersection between the source and destination images (or ROIs), allowing them to vary independently.

Examples:

polar_transforms.cpp.

Member Data Documentation

int IplImage::align

Alignment of image rows (4 or 8). OpenCV ignores it and uses widthStep instead.

int IplImage::alphaChannel

Ignored by OpenCV

int IplImage::BorderConst[4]

Ditto.

int IplImage::BorderMode[4]

Ignored by OpenCV.

char IplImage::channelSeq[4]

ditto

char IplImage::colorModel[4]

Ignored by OpenCV

int IplImage::dataOrder

0 - interleaved color channels, 1 - separate color channels. cvCreateImage can only create interleaved images

int IplImage::depth

Pixel depth in bits: IPL_DEPTH_8U, IPL_DEPTH_8S, IPL_DEPTH_16S, IPL_DEPTH_32S, IPL_DEPTH_32F and IPL_DEPTH_64F are supported.

int IplImage::height

Image height in pixels.

Examples:

polar_transforms.cpp.

int IplImage::ID

version (=0)

char* IplImage::imageData

Pointer to aligned image data.

char* IplImage::imageDataOrigin

Pointer to very origin of image data (not necessarily aligned) - needed for correct deallocation

void* IplImage::imageId

" "

int IplImage::imageSize

Image data size in bytes (==image->height*image->widthStep in case of interleaved data)

struct _IplImage* IplImage::maskROI

Must be NULL.

int IplImage::nChannels

Most of OpenCV functions support 1,2,3 or 4 channels

Examples:

polar_transforms.cpp.

int IplImage::nSize

sizeof(IplImage)

int IplImage::origin

0 - top-left origin, 1 - bottom-left origin (Windows bitmaps style).

struct _IplROI* IplImage::roi

Image ROI. If NULL, the whole image is selected.

struct _IplTileInfo* IplImage::tileInfo

" "

int IplImage::width

Image width in pixels.

Examples:

polar_transforms.cpp.

int IplImage::widthStep

Size of aligned image row in bytes.
