Re: [CFCDEV] cfx_imageinfo error on 64 bit operating system

Hi Diego, I'm glad cfimage does everything you need to replace
cfx_imageinfo.
Does anyone know how I can find the DPI of an image using ColdFusion now?
That was the primary reason we had used cfx_imageinfo, but now that we're
on 64 bit machines, we need an alternative.
The ImageInfo() function in CF does give us a pixel size attribute but I'm

Sorry for the cross-post on coldfusionoo and cfcdev - just wanted to get
this message to everyone who might be interested.
Message copy follows, but if you have any comments it would be great if you
could make them over on the coldfusionoo thread.

That is what I do in ValidateThis when validating a struct rather than
an object. You'd need to have a way of easily adding behaviours to the
wrapper object. Perhaps a base object that just wraps, and if you need
extra behaviours you could extend the base wrapper with a concrete
wrapper for that object?

Barney,
That's why I pass a fieldlist argument in. If "numberOfGrandchildren"
isn't in the fieldlist then I don't calculate it.
Does that not cover that case?

By front-computing all those values, you're necessarily doing a LOT of
extra work to build up data that isn't needed universally. A dataDiff
for age is simple, but what if it's numberOfGrandchildren (which is
guaranteed to require database access to answer). Using a method for
lazy loading the data can be a HUGE performance boon, as well as

For me, I would probably pass AgeOfMajority into my service component
and have it return an "isMinor" column. If that wasn't a possibility,
then I would have my page controller add that column to the query.
I would also have an "age" column in the query returned from the service
(assuming it was in the fieldlist).

Peter,
Pretty much:
qUsers =
Application.Users.getUsers(has EmailAddress=true,fieldlist="f irstName,
lastName, age, fullName, homeLatitude, homeLongitude")>
(for example)
That would work. I actually have empty fields in my query for the
calculated fields and then if any of them exist, I loop over the query

bboisv...@gmail.com (Barney Boisvert) — Fri, 07 Jan 2011 22:17:44 UT

Rather than just reconsidering the rule, you might simply replace it
with "no multi-term expressions in the view". Not a viable goal in
all cases, but pretty darn close. Views shouldn't have logic apart
from that directly concerned with the view structure (looping rows in
a table, conditionally displaying an action button, etc.). All the

A little busy, but doing very well!
So I'm guessing you have something like:
userQuery = UserService.getAllUsers("first Name, lastName, age, fullName, homeLatitude, homeLongitude")
I guess if you have some logic which determines generically which fields are from the db and which are calculated, you could write well encapsulated code which would first construct a base query using SQL and then "for each calculated field" would call:

Peter,
Indeed! I'm excellent. Hope you are well also.
I have a "fieldlist" argument on my service methods. So, my
"getEmployees" method returns a query with the fields requested. It
doesn't matter that some of those fields are created by SQL and others
by post-processing. At which point I am only doing post-processing for

henryho...@gmail.com (Henry Ho) — Fri, 07 Jan 2011 21:32:24 UT

I have another idea, see what you guys think.
Since the NoSQL DB driver I'm using is returning me a Struct for a doc (most
of them do), could I have just write a proxy that wraps the struct, and add
behaviors on it? instead of decompose the Struct into properties of a bean?
The pro is that I don't really need a DAO per Bean, but I'll need to write

Hey Steve,
Long time no chat! Hope you're doing well?
OK, trivial example, I get firstName and lastName back and I want to display fullName. If I don't have an object where I can put a getFullName() method, I have to either iterate over the query in a service class to preprocess or duplicate the #firstName# #lastName# code in every view which is fine until I want to add middleInitial to everywhere I display the full name and then becomes a PiTA in terms of maintenance.
