Regex Tutorial - Parentheses for Grouping and Capturing
Use Parentheses for Grouping and Capturing
Some of the above checks may be a bit excessive, for example, is Mozilla ever spelled mozilla?, but it is also pretty silly to have code fail just because of this 'easy to prevent' condition. There is apparently no final consensus that all Gecko browsers will have to use Gecko in their 'user-agent' string but it would be extremely foolish not to since this would force guys like us to make huge numbers of tests for branded products and the more likely outcome would be that we would not.

The next level is Q16 HDRI, that takes precision to 32 bit floatingpoint values which allows you to deal with image values that become very smallor very large without the rounding and clipping effects of images. You caneven deal with negative values, especially in some colorspaces. Essentiallyit is used to prevent image data loss when processing images in extremes such aswhen using HDRI images, Fourier Transforms, or just high levels ofcompression, expansion you may get in mathematical processing of raw data.

We had previously defined the above test using the search value l? (thanks to David Werner Wiebe for pointing out our error). The search expression l? actually means find anything, even if it has no l (l 0 or 1 times), so would match on both strings. We had been looking for a method to find a single l and exclude ll which, without lookahead (a relatively new extension to regular expressions pioneered by PERL) is pretty difficult. Well, that is our excuse.

It is used to hold freeform global settings that define or modify the reading and image processing of all the images. An example of which is the "" setting that causes some operations to output general information about there actions, including more verbose identify output.

A heartfelt and humbling apology is offered. Those of you who were tearing your hair out in frustration can now stop.
