Thanks for the zip file ... even using these lib's and dll's, the buffer is
still being written with all 0's. If I could ask you one last favor and
try this very simple program on your windows system and let me know what
const char* fn = "C:\\Data\\CMU-3.mrxs";
openslide_t* openslide = openslide_open(fn);
uint32_t *data = new uint32_t[512 * 512];
openslide_read_region(openslide, data, 0, 0, 0, 512, 512);
for (int j = 0; j < 10; ++j)
