Content-Type: text/plain; charset="iso-8859-1"I use GDAL for mapped image data (by creating a .vrt file for each image).
ImageMagick has support the formats you mention. If you are hoping to
interpret indexed color images as data you need to watch for optimizations
that can scramble the original relationship between colors and data values
(some tools used to apply annotations will "optimize" the color palette,
presumably to "free up" some colors for annotations, but they can leave you
with an image where similar colors are far apart in the color LUT).> Deal All,

Sometimes it can be hard to figure out which HDF doodad is still open.
I use this (c code) snippet to point to the culprit:norphans = H5Fget_obj_count(file->file_id, H5F_OBJ_ALL);
if (norphans > 1) { /* expect 1 for the file we have not closed */
int i;
H5O_info_t info;
char name[64];
hid_t * objects = calloc(norphans, sizeof(hid_t));
H5Fget_obj_ids(file->file_id, H5F_OBJ_ALL, -1, objects);
for (i=0; i<norphans; i++) {
H5Oget_info(objects[i], &info);
H5Iget_name(objects[i], name, 64);
printf("%d of %zd things still open: %d with name %s of type
%d", i, norphans, objects[i], name, info.type);
}
