C library used for reading and writing FITS files

Whats new in version 3.33:
• Modified the imcomp_decompress_tile routine to ignore any numerical overflows that might occur when using Hcompress to decompress the image. If Hcompress is used in its 'lossy' mode, the uncompressed image pixel values may slightly exceed the range of an integer*2 variable. This is generally of no consequence, so we can safely ignore any overflows in this case and just clip the values to the legal range.

• The default tiling pattern when writing a tile-compressed image has been changed. The old behaviour was to compress the whole image as one single large tile. This is often not optimal when dealing with large images, so the new default behavior is to treat each row of the image as one tile. This is the same default behavior as in the standalone fpack program. The default tile size can be overridden by calling fits_set_tile_dim.

• Fixed bug bug that resulted in a corrupted output FITS image when attempting to write a float or double array of values to a tile-compressed integer dat...
