# wrong compression type reported for TIFF's#309

 Hi. I'm using Wand (Mac 10.11.6. Wand(0.4.3), imagemagick(6.9.6-2) and dependencies installed through brew, pyenv running 3.5.2) to, among other things, verify the properties (colorspace, depth, compression, etc. ) of a huge batch of TIFF's. Wand is reporting that the compression type of some of the TIFF's is 'b44a,' which is far as I know is not supported by the TIFF format. Looking at the images using Imagemagick's identify (identify -format "%C" [path\to\tiff]) shows them as 'None' or uncompressed. EXIFTool as well as a hex dump of the files confirm that they are uncompressed. Testing it out a little, a TIFF using JPEG compression reports as 'JPEG2000' while a Group 4 encoded bitonal image reports as 'fax.' Thanks for your help. And thanks for Wand. The text was updated successfully, but these errors were encountered:

 Ah! Looks like COMPRESSION_TYPES was mapped to ImageMagick-7's CompressionType enumerators. Should be a simple fix.
