image manipulation in coldfusion?
Author: Webmaster at FastTrack On Line
Short Link: http://www.houseoffusion.com/groups/cf-talk/thread.cfm/threadid:42585#220531
I'm catching up on this thread, but ...
I do think CF should have image manipulation. I'm not about to go and learn
Java or anything vaguely "codey" if i can possibly help it, not enough hours
in the day and I bought CF for the very reason I would never have to learn
Java! Programming at that level just isn't for me, I find it tedious.
I have used http://www.imagemagick.org/script/index.php as
a work around
and it works just fine, and it's free :-)

I have a few things I would add/improve for the next version. Please feel

----- Excess quoted text cut - see Original Post for more -----
Thanks Roger. I am aware of this but I am still not sure on what's the best
way to handle it.
Until now I tried to leave out any form of "logic" from the CFC; in my
vision it only has to perform the basic operations, then it's up to the
developer to wrap any logic around it (see the post about conditional
cropping).
The CFC could check if the crop area exceed image's dimensions and adjust
the cropping area. I still have mixed feelings about this... It will surely
make the CFC more "monkey proof", but I don't want a component that try to
"outsmart" its user. Personally I would again, extend the CFC and add a
"saveCrop" method that just wrap the logic around the base method.
Feedback and opinions on this would be very much appreciated.

My CFC offers all the basic functionality you need for this, but you have to
perform the logic (if exceeds crop, if not let it alone) on your own. In my
opinion the best thing to do would be to extend the CFC and put your logic
there. This would allow you to first, separate the logic from the core
functionality, then it will make easier to update as soon as I will release
an updated version of the CFC since you would not change my code directly.

OK, most of the meat and potatoes of what I'm doing is in this
cfscript block. I'm sure that it's possible to encapsulate this in a
much neater fashion, I just chose not to.
<cfscript>

}
</cfscript>
If this isn't enough, I can make a zipped copy of the CFM template available.

as does mine....look at the scaleBy attribute....ensures that dimension is

Well ya weren't following that close Kevin....I posted CFC methods to check
image dimensions AND another to re-size....a couplde of CFIFs and those will
get ya what ya want ;-)

Put it out there Pete. I'd be interesting in seeing what else you added to
it, There's a few things that I wish tmt_img did differently. All in all,
it's a great piece of code though. Thank you Massimo.

Massimo's tag has getHeight and getWidth methods. Call those on an image,
then check accordingly.

Thanks guys - I've been following this with interest as I have a
particular resizing challenge at the moment.
What I'm looking for is a way to test the size of an image before its
displayed and then resize it if its width exceeds 250px - if 250px or
less then it can be left alone.
Not sure if tags like Massimo's support that or not.
Any suggestions please.

Massimo: Just to let you know... I was playing around with your CFC, and
noticed that on some images (usually horizontally oriented ones),
bufferedCrop() would throw an "outside of raster" error. I was able to
fix it by modifying the code to check for crop operations that exceed
the height of the image.
With that said, thanks for putting the code out there.

ImageCR3 does that impeccably. When specifying dimensions for the resize
you put >250x>100 and it will resize the width down to 250 if greater
and/or the height down to 100 is greater than 100 with prefect quality
results.

yep...mine is great for good old JPG/GIF manip....but when ya hit the TIFFs
it gets fuzzy....BTW I do have some code to convert multi-page TIFFs to PDF
(one page per page in TIFF)....compliments of the wonderous package iText

You can use Java for image manipulation and achieve good quality results.
You just have to dig the APIs a little more. That's what I tried to do when
I wrote version 2.0 of my CFC and I achieved a huge increase in quality.
You can get it from here and give it a try (it's free):

Bryan,
How is the quality on the resizes for that? I've used some java stuff
like that before and had issues with the quality. Things seemed to come
out a little distorted. From what I can see in the component, it doesn't
seem like there's any kind of argument for the quality. Let me know if
you've had similar experiences. For some of the people I've tried doing
this for, they're artists and bands and people who are a little more
particular about the resize quality so I really need it to be top notch.
Let me know.

The personal/non-commercial "version" differs only by license.
You get the same download and binary as commercial customers.
You can upgrade to a commercial license for the difference in
cost between these license types. The same upgrade policy applies
for upgrades to future versions of ImageCR, eg. ImageCR4.

If there a difference in quality or control in the personal version vs.
the full version? Or just the license? I'm only looking at using this
for a personal site right now but may expand it later. Is there a way to
"upgrade" the license to the full version or would I just have to buy
from scratch?

It is optimized native code, like important parts of Java. High quality

The HoF site is down. Care to share that code via email or a straight link?

That is the question :) if your host is happy to install it then its not a
problem , if he is or you are on Linux then you will probably better off
using one of the free alternatives such as Bryan's (some one was listening
;-)) or the Alagad image component which I've also heard great things about.

Yes, yes, yes - use ImageCR3 if you have the chance. I was going to
recommend it myself. I'm sure I haven't seen them all, but ImageCR3 looks
FAR better than any other resizing tag out there. I don't know how they do
it, but they do it well.

I use Massimo's tmt_img 2.0 (http://www.olimpo.ch/tmt/cfc/tmt_img/)
and it's great if what you need to do is crp/resize images. It's all
CFC so no custom tags, nothing to configure. Oh, and it's free.
I extended it to add a "max size" that resizes so that no dimension is
greater than the passed in value, which makes it even more invaluable
for me.

We use imageCR3 and love it. I only wish it was java based so we could use
it on linux.
-e
now i'm torn.
I've used ImageCR3 in the past and yes, it's a great product with
absolutely fantastic (FANTASTIC) support.
But what I like about Alagad is the fact that it's a straight CFC. No
custom tags to install (which may not be a big issue unless you're in
a shared environment and the host likes to charge for custom tag
installations).

Wow... yeah...
Alagad is nice, but the stuff from eFFlare is awesome.
If you are in a shared envirnment I would go with alagad.

I'll ditto Alagad. It's only like 75 bucks and well worth the price.
Yes, there are free alternatives, but this one is so easy and simple
to use, I'd still recommend it.

I'd check out the Alagad Image Component at www.alagad.com - it's
native CF. While it's not free, it's so cheap that you'll make back
the dough the first time you use it in terms of time saved.

I use built in java stuff to do this with jpegs .. take a look at the
image.cfc file included in the CFFM distributino (www.webworksllc.com/cffm)

search the archives for my name or e-mail and "ThumbIt" or mabye "image
manipulation". I've posted my CFC methods that use Java to resize images
and get image pixel height/width about 5-10 times now....does not work with
TIFFs
I don't have the code handy right now or I'd post it yet again ;-)

So I'm wondering what some of you use to manipulate images in CF. I've been
wanting something like this for a while but it's always gotten put off.
At the very least I need to be able to resize images and get their height
and width. More than that would be nice, but not necessary.
Can anyone offer any suggestions?
