trim function

[Nick]

Hi there,

does any know how i can do a 'trim on canvas' sort of function. If my canvas
is bigger than my draw/animation etc, then how do i shrink my canvas to wrap
around my object? (there's a Trim in PS but i can't seem to find this or a
crop function in Flash mx 2004).

- thanks for any comments.

Click on your largest object such as the background clip and find the width
and height in the properties window. Click on the stage that is showing or
click Modify/Document/Settings, click on size and enter the width and height
you found in the properties of your background clip, this will resize the
stage to fit the background.

Flash MX 2004 doesn't have a crop or trim.

I am trying to trim unessasary data from a webpage. The code I have found does
work, but I am trying to better udnerstand how it works, and if there is a
better way to do it. If anyone could help that would be great. Here is the
code...

I am especially looking for an explanation of what "<[^>]*>" does in the trim
function.????

<CFHTTP METHOD="Get"

URL="http://nikonimaging.com/global/products/digitalcamera/slr/d2x/index.htm"
RESOLVEURL="Yes">
</CFHTTP>




<CFSET temp_page=#CFHTTP.FileContent#>
<cfset temp_page = trim(rereplace(replacenocase(cfhttp.filecontent, "border=0
alt=""><br>", ""), "<[^>]*>", "", "all"))>


<cfset location1 = #find("DX Format with 12.4 effective
megapixels",temp_page)#>

<cfoutput>#location1#</cfoutput>


<cfif location1 EQUAL 0>
<cfset ck=1>
<cfelse>
<cfset location2 = #find("data for the same shot",temp_page)#>

<br><cfoutput>#location2#</cfoutput><br>

<!--- <cfset
strip="http://www.sonystyle.com/is-bin/INTERSHOP.enfinity/eCS/Store/en/-/USD/SY_
DisplayProductInformation-Start?CategoryName=hid_cameras_ServicePlans_Camera s&Pr
oductSKU=DSCT7&TabName=specs&var2=##Mid(temp_page, location1, location2 -
location1)"> ----->
</cfif>



<cfset ron = "#Mid(temp_page, location1, location2 - location1)#">
<!--- <cfset ronlist = #rereplace(ron, "&##0149;","<BR><li>","all")#>
<cfset ronlist = #rereplace(ronlist, "<BR>","<ul><BR>")#>
<cfset ronlist = "#ronlist#</ul>">--->
<cif ck EQ "0">
<cfoutput>
#ron#
</cfoutput>Text

Now, I'm not a regExp guru actually, so I might go wrong, but here's my
translation:

The "<[^>]*>" will match any <TAG> that contains at least something between
the <>.

Step by step (, ooh, baby!) :

< start matching by finding a "<"
[^>] match a character, which is NOT ">"
* extends the previous condition so that 0 to zillion occurences of
anything but ">" is ok.

> the match must end with a ">"

Even though the ">" is the last character we want to match, the regExp does
not know that until we've found something else first. The processing goes from
left to right. That's why the formula in many regExps often goes as:

1. Find the starting character(s)
2. Find anything BUT the ending character(s)
3. Find the ending character(s)

The "<[^>]*>" will thus match "<>" and "<table border='0'>". If there's a
string "<ta>ble>" it'll only match the "<ta>". Nothing will be done to the
"ble>".

To me, your current code makes sense, if you're referring to tags as
"unnecessary data".
