It seems to me that the usage of TkPhotoImage is not like others Ruby/Tk ...
a.copy(b, :subsample=>5) # is OK. a, b are instance of TkPhotoImage
but if you want subsample x y :
a.copy(b, :subsample=>'5 5') # ==> Error ...
a.copy(b, :subsample=>[5, 5]) # ==> Error ...
I found the only way is :
a.copy(b, '-subsample 5 5') # OK
Same problem on read, write ... etc
a.read('image.gif', :shrink) #==> Error
a.read('image.gif', 'shrink') #==> Error
The only way to do it is :
a.read('image.gif', '-shrink')
Is there some reasons to desing TkPhotoImage this way ?
Thank you.
