I get the following error at the browser:
ArgumentError in ImagesController#upload
invalid geometry string `110×''
... for the call to change_geometry with an explicit size
(''110x'') as
the geometry string:
def make_thumb (the_img)
require ''RMagick''
size = "110x"
debugger if ENV[''RAILS_ENV''] ==
''development''
img = Magick::Image.from_blob(the_img.img_data).first
img.change_geometry(''110×'') {|cols, rows, i| i.resize!
(cols,rows) }
# img.change_geometry("110×") {|cols, rows, i| i.resize!
(cols,rows) }
# img.change_geometry("#{size}") {|cols, rows, i| i.resize!
(cols,rows) }
end
... but it all works OK when the size is buried within "#{size}".
The debugger doesn''t seem to see any difference:
(rdb:1) l
[112, 121] in ./script/../config/../app/controllers/
images_controller.rb
112 def make_thumb (the_img)
113 require ''RMagick''
114 size = "110x"
115 debugger if ENV[''RAILS_ENV''] ==
''development''
=> 116 img = Magick::Image.from_blob(the_img.img_data).first
117 img.change_geometry(''110×'') {|cols, rows, i|
i.resize!
(cols,rows) }
118 # img.change_geometry("110×") {|cols, rows, i| i.resize!
(cols,rows) }
119 # img.change_geometry("#{size}") {|cols, rows, i| i.resize!
(cols,rows) }
120 end
121
(rdb:1) p size
"110x"
(rdb:1) p (''110×'')
"110×"
(rdb:1) p ("110×")
"110×"
(rdb:1) p ("#{size}")
"110x"
... and I sure don''t. Am still trying to figure out which way is up
with much of this, and would appreciate any insight as to what''s going
on here.
Thanks!

Very Good! Here''s a geometry string pasted into vi from the rmagick page, into ''foo'', versus keystroking the same string into ''bar'' [pf@gezora imgr]$ cat foo "110×" [pf@gezora imgr]$ cat bar "110x" [pf@gezora imgr]$ cat foo | od -b 0000000 042 061 061 060 303 227 042 012 [pf@gezora imgr]$ cat bar | od -b 0000000 042 061 061 060 170 042 012 012 bar''s octal ''170'' makes a good ''x'' for the geometry string ... foo''s ''303'' ... not so good. won''t do that anymore. thanks!
