Jpeg2000Image * Jpeg2000ImageFactory::createJpeg2000ImageToRead ( char *  filename,
BoundingBox< double >  bbox,
double  resx,
double  resy 

Create an Jpeg2000Image object, for reading.

Bbox and resolutions are not present in the JPEG2000 file, so we precise them. All other informations are extracted from JPEG2000 header. We have to check consistency between provided bbox and resolutions and read image's dimensions.

Negative resolutions leads to georeferencement calculation. Both resolutions will be equals to 1 and the bounding box will be (0,0,width,height).
