VIPS_LIBRARY_AGE
|
||||
- better support for bscale / bzero in fits images
|
||||
- deprecate vips_warn() / vips_info(); use g_warning() / g_info() instead
|
||||
- vipsthumbnail supports much fancier geometry strings
|
||||
- vips_thumbnail() has new @size option
|

|
||||
8/12/16 started 8.4.5
|

- allow libgsf-1.14.26 to help centos, thanks tdiprima
