Morph-M

Description:
----------------------------------------
Impossible d'enregistrer une image en ppm. On obtient l'erreur "Error in a
dynamic_cast" bien que le format de l'image soit correct (couleur, 3 UINT 8).
Un petit programme pour tester :
<CODE>
#include <morphee/imageIO/include/morpheeImageIO.hpp>
#include <morphee/image/include/morpheeImage.hpp>
int main(int argc, char *argv[]) {
morphee::ImageInterface img;
morphee::RES_C res_io;
std::string input_filename, output_filename;
morphee::imageIO::initImageIO();
input_filename.assign(argv¹);
output_filename.assign(argv²);
res_io = morphee::imageIO::fileRead(img, input_filename);
if ( (res_io!= morphee::RES_OK) || (img==NULL) ) {
std::cout << "Unable to read image" << std::endl;
return 1;
}
std::cout << "read image...OK" << std::endl;
std::cout << img>getDataCategory() << " " << img->getDataType()
<<std::endl; //verification du format
if ( (res_io = morphee::imageIO::ppmFileWrite(img, output_filename))!=
morphee::RES_OK) {//remplacer par bmpFileWrite pour voir la difference
std::cout << "Unable to write image " << res_io << std::endl;
return -1;
}
std::cout << "write image...Ok" << std::endl;
return 0;
}
</CODE>
Certainement dans imageIO_PGM.cpp, le cast suivant ne passe pas :
const Image<UINT8> _imTemp = dynamic_cast<const Image<UINT8>*>(imageOut);
if(!_imTemp) {
MORPHEE_REGISTER_ERROR("Unable to downcast the image");
return RES_ERROR_DYNAMIC_CAST;
}

Change: status: "pending" -> "accepted"
Comment:
Je savais pas que le format ppm existait vraiment ;)
Bon en tout cas, un dynamic cast c qd mm assez violent.
