Detailed Description

Read/write images with various image format.

The code below shows how to convert an PPM P6 image file format into a PGM P5 image file format. The extension of the filename is here used in read() and write() functions to set the image file format (".pgm" for PGM P5 and ".ppm" for PPM P6).

#include <visp/vpImage.h>
#include <visp/vpImageIo.h>
int main()
{
#ifdef UNIX
std::string filename("/local/soft/ViSP/ViSP-images/Klimt/Klimt.ppm");
#elif WIN32
std::string filename("C:/temp/ViSP-images/Klimt/Klimt.ppm");
#endif
vpImageIo::read(I, filename); // Convert the color image in a gray level image
vpImageIo::write(I, "Klimt.pgm"); // Write the image in a PGM P5 image file format
}

This other example available in tutorial-image-reader.cpp shows how to read/write jpeg images. It supposes that libjpeg is installed.

#include <visp/vpImageIo.h>
int main()
{
try {
vpImageIo::read(I, "lena.jpg");
vpImageIo::write(I, "lena.png");
}
catch(...) {
std::cout << "Unsupported image format" << std::endl;
}
}

Member Function Documentation

void vpImageIo::read ( vpImage< unsigned char > &  I,
const char *  filename 
)
static

Read the contents of the image filename, allocate memory for the corresponding greyscale image, update its content, and return a reference to the image.

If the image has been already initialized, memory allocation is done only if the new image size is different, else we re-use the same memory space.

Always supported formats are *.pgm and *.ppm. If libjpeg 3rd party is used, we support also *.jpg and *.jpeg files. If libpng 3rd party is used, we support also *.png files. If OpenCV 3rd party is used, we support *.jpg, *.jpeg, *.jp2, *.rs, *.ras, *.tiff, *.tif, *.png, *.bmp, *.pbm files.

Parameters
I: Image to set with the filename content.
filename: Name of the file containing the image.
Examples:
displayD3D.cpp, displayGDI.cpp, displayGTK.cpp, displayOpenCV.cpp, displaySequence.cpp, displayX.cpp, displayXMulti.cpp, fernClassifier.cpp, histogram.cpp, imageDiskRW.cpp, keyPointSurf.cpp, manDisplay.cpp, photometricVisualServoing.cpp, planarObjectDetector.cpp, poseVirtualVS.cpp, testClick.cpp, testConversion.cpp, testCreateSubImage.cpp, testIoPGM.cpp, testIoPPM.cpp, testMouseEvent.cpp, testReadImage.cpp, testSurfKeyPoint.cpp, testTrackDot.cpp, testUndistortImage.cpp, testVideoDevice.cpp, trackDot.cpp, trackDot2.cpp, trackDot2WithAutoDetection.cpp, trackKltOpencv.cpp, trackMeCircle.cpp, trackMeEllipse.cpp, trackMeLine.cpp, tutorial-blob-auto-tracker.cpp, tutorial-ibvs-4pts-image-tracking.cpp, tutorial-image-reader.cpp, tutorial-image-simulator.cpp, tutorial-image-viewer.cpp, tutorial-mb-edge-tracker.cpp, tutorial-mb-hybrid-tracker.cpp, tutorial-mb-klt-tracker.cpp, tutorial-pose-from-points-image.cpp, tutorial-undistort.cpp, and tutorial-viewer.cpp.
