1. Is looking for a slash going to be compatible on all platforms? Where is
the path string coming from?
2. Catching `NumberFormatException` to "check" if something is a number is bad
form
3. It will allow `@0x` and `@-1x` etc...
4. Consider using a regular expression, it is much more concise and intended
for this kind of matching
Here's a regular expression for this:
Pattern SCALED_PATTERN = Pattern.compile(".*@[1-9][0-9]?x(\.[^\.]+)?");
The above will match any path that ends with `@` followed by a number from 1 to
99, followed by an `x`, optionally followed by an extension that does not
contain a dot. No need to check for slashes.
