Version 0.94: Beta 5
|
||||
* (bugfix: fix cacheing code to allow refreshing current image after flip etc.)
|
||||
* (feature: use 'f' to flip image vertically, in case FreeImage sucks)
|
||||
* feature: sort filenames to sort numbers in human-friendly order
|
||||
* feature: show index within sorted list
|
||||
* feature: ctrl-C puts current image filename (with full path) in the clipboard
|
||||
* change: change the border control keys to 'b' instead of 'f' for next feature
|
||||
* feature: use FreeImage.dll if it's available
|
||||
* bugfix: fix bug in right or bottom cursor region due to internal cleanup
