I meant doubles, but I guess floats will do as well.

Thanks for the info. I would like to add that casting the width and height to floats before finding the center point of the rotation is the most accurate thing to do. Otherwise, you’ll find that there is a column/rows of pixels missing from one side of the image.

You will want to work through the directions
http://www.flickr.com/services/api/misc.userauth.html

I was developing for a desktop app and took three steps
public void authNewUser() {

constructFrobUrl()//flickr.auth.getFrob

createAuthURL()
//used os to open browser to the URL
“open http://flickr.com/services/auth/?api_key=“+ this.akey + “&perms=delete” + “&frob=” + this.frob + “&api_sig=” + this.sig

getToken()//flickr.auth.getToken
}

Quick question. I couldn’t figure out how to authenticate the app? Thanks

thanks for this man .
but i think putting the image to your image folder in the war is not a wise idea.. is there a way to do it in the machine file system and then read it ?

Comment on Handling Ruby’s String.each_char Iterator by John P

I needed this to do a simple cleanup of strings entered by the default io.readline call. If the user hit backspace, the \b would get added to the string along w/the characters they were trying to get rid of. Here’s an inelegant solution:

def clean(line)
#silly little routine to parse backspaces in the input line…
retval = “”
line.each_byte do |ch|
if ch == 8 #backspace
retval.chop!
else
retval << ch
end
end
return retval
end

If you click on the source in the docs, you get:

# File lib/jcode.rb, line 209
def each_char
if block_given?
scan(/./m) do |x|
yield x
end
else
scan(/./m)
end
end

so yeah, just do “string”.scan(/./m)

@Nick Great comment, I don't work with a whole lot of multi-byte character encodings. In this case, Jcode would be the way to go for Ruby 1.8. I haven't played much with Ruby 1.9 but I am excited to play with the better supported encodings that are baked right in.
