Re: Adding a border to text using CFImage

2012-02-21 Thread Leigh 

Terry,

The examples on the website say if you are using it with CFWheels you just 
[call the] getArt() function since it is made available to your controllers and 
views.. Otherwise, you need to create an instance of the component first and 
call init(). Then use yourInstance.getArt() instead of just getArt(). Try the 
code in the Basic Example section. That should work for you.

Leigh,

Here is my test page using the Basic Example as you said:

body
cfset wordart = createObject(component, wordart).init() /

/html
It is running in c:\inetpub\wwwroot\wordart\
The 2 files, test.cfm, wordart.cfc are in that folder with no subfolders.

Here is the error:
The CFML compiler was processing:

Terry - Works perfectly with CF9. Any chance you are using CF8? I do not think 
implicit structures were supported in function calls until CF9.

I tried it in CF9 and it works, thank you a bunch leigh for putting up with
my lack of knowledge.
So this cfc will not work using CF8 or could you show me a way to call it in

LEIGH,
This is crazy again.
I uploaded the folder with the test.cfm and the cfc to a CF9 server and as I
said it worked.
I sent you my last reply stating that.
Went back and reran the file and I get red x's where the demo images were
but the plain text is there net to the red x.
I deleted the folder, reuploaded and red x's again.
I looked at the directory structure and it has created a tree of new folders
and the png images with superlong filenames are there.
I then hand typed the url to the images and they displayed perfectly.

No worries. It was a fun question .. and I learned something new myself. While 
perusing the cfc source I figured out how to create the outer stroke effect :)


 So this cfc will not work using CF8 

I think it should work if you get rid of the CF9 specific syntax. But you would 
have to try it to be sure. 


Since CF8 does not allow the implicit syntax within function calls, just 
declare the options structure separately. 

    cfset attr = {style=simple,  etcetera ...}
    cfoutput #wordart.getArt(text='Start',options=attr )#/cfoutput

The url in the generated image tags is probably pointing to the wrong location. 
You can change the defaults for the various paths in the init() function: ie  
init( urlPath, artDir, fontDir)

Leigh it went from better to worse.
I said it worked when I put the 3 files in a folder off wwwroot called
wordart in my laptop with CF 9.
It works perfectly.
I then uploaded it to my windows 2003 server with CF 9 into a sub folder
called wordart in my website.
It worked PERFECTLY ONCE. now if I go back there I get this error:

Variable ___IMPLICITARRYSTRUCTVAR0 is undefined.
Why does it run without errors on my local machine and not the server.
I googled the error and Ben Nadel has a post on it, but I can't decipher
the reason it's happening on one and not the other.

Leigh,
I removed the 2 lines and pasted in the example lines with a semi colon at
the end.
The result is a solid image, but no stroke.
Here's what I added:
   // color in the text
   Color = createObject(java, java.awt.Color);
   graphics.setColor( Color.decode(##80aa1c) ); 
   graphics.fill( shape );
   
   // create a thin border 
   stroke = createObject(java, java.awt.BasicStroke).init( 1 );
   graphics.setStroke( stroke );
   graphics.setColor( Color.decode(##800080) );
   graphics;

Can you see anything wrong?

Check out the Alagad Image Component

http://www.alagad.com/projects.imageComponent

I have used it in the past, pre-CFImage.  I know that it works on CF7 and I
just tested it and wrote text to an image using CF 9. If anything it will
provide examples of manipulating fonts.

Sorry about the goose chase earlier.

Well when I play with the numbers in the code it seems if I raise the init
setting it widens the stroke/border, but the thickness seems to go inwards
instead of outwards from the outside edge of the text.
Is that a better explanation?
His code is awesome, I just would like to know how to size things and

Re: Adding a border to text using CFImage

2012-02-20 Thread Leigh 

  Is that a better explanation?

Yep. If you think about how the border effect is created, the behavior makes 
sense. Basically you are working with a glyph, or a shape of the text. Stroking 
affects how that shape is filled. It does not change the shape itself. So the 
thickness has to move inward (so to speak).

I am no artist. But I think the effect you are looking for is often achieved by 
overlaying a smaller shape over a slightly larger one. Similar to creating a 
shadow effect.  It should be possible to apply the same concept to text. But I 
would have to look around to see if that is the right way to approach it.


Btw: It goes without saying if there is an existing library that supports text 
borders, by all means use it ;-) No reason to reinvent the wheel. But it is fun 
talking about how all this stuff works internally  ;-)

Inside, outside and middle.

Hopefully he will reply as the documentation as to what it can do is awesome

Re: Adding a border to text using CFImage

2012-02-20 Thread Leigh 

 Check out the Alagad Image Component


Yeah, I was going to suggest taking a look at existing image components. Do you 
know if it supports text borders? Nothing jumped out at me from a brief look at 
the documentation.

Re: Adding a border to text using CFImage

2012-02-20 Thread Leigh 



 I just sent a request asking if his wordart.cfc is
 still active and open source.

Great. I would be curious if there are any updates.  

BTW: Did you try using the non-cfwheels syntax  ie wordArt.getArt()? 
Because that worked fine for me.

Leigh,
All I did was to run the index as is.
I do not know where to change the syntax which is probably why I am getting
errors.

Adding a border to text using CFImage

2012-02-19 Thread Terry Troxel 

I have searched all over and so far am empty handed trying to put a 

color border or stroke around text created with CFImage.

I also own Efflare's Imageflare and don't see anything in there either.

If someone has any suggestions or links, I would appreciate it greatly.

 

Terry

Terry,
I remember seeing something about that a while and tried to hunt it up for
you. I could not remember the name of it so I could not find it via the
google... I was cleaning out my hard drive just now and I ran across it...
Talk about dumb luck. w00t!!!

This is the site with some docs and demos:
http://www.codecurry.com/2009/12/introducing-wordart-for-coldfusion.html

But the DL link is hosed. Luckily I saved a version of the file.

It is under the BSD licence so I can redistribute the code. Hot damn do I
love OSS!

https://docs.google.com/open?id=0B_JS0uv8wk1ZNDMwNTkwM2YtMWU1Mi00MDFkLTgxOGUtODU5NGU4NDg1NzQ5

Every once in a while being digital pack rat pays off.

G!

Re: Adding a border to text using CFImage

2012-02-19 Thread Leigh 

 Post it anyways. I am curious.

I skimmed the cfc and it is essentially doing the same things internally.  Just 
more and a lot fancier :) It grabs the underlying graphics and uses draw(), 
setStroke(), etcetera to fill in the text, create borders, etcetera.


Here is an old entry on creating a text outline. With a few small changes, it 
could fill in the text shape with one color and use setStroke to create a 
border of another color:

ie Change these two lines:

   graphics.setColor(textColor);
   graphics.draw(shape);

... to something like this

   // color in the text
   Color = createObject(java, java.awt.Color);
   graphics.setColor( Color.decode(##80aa1c) ); 
   graphics.fill( shape );
   
   // create a thin border 
   stroke = createObject(java, java.awt.BasicStroke).init( 1 );
   graphics.setStroke( stroke );
   graphics.setColor( Color.decode(##800080) );
   graphics

RE: Adding a border to text using CFImage

2012-02-19 Thread Eric Roberts 

If you do a search here, last year there was a discussion about using java
to add and manipulate text on the fly.  Look around October-ish.  I was
doing a contract ad a casket maker and they did websites for funeral homes.
One of the site features was being ablet o make a slide show of images plus
custom text that had you can put saying or whatever you wanted.  This code
was based off of some work ben Nadel did and I expanded on that with another
list member (I am forgetting her name ATM...sorry, I am horrible with
names).  That discussion may help you.  I did post the final code I had to
the list.
