[flexcoders] JPGEncoding of mx:Image
Hi,
I'm trying to capture a loaded image into mx:Image. I'm able to sort of
write the bitmapdata of an image to a file except when I load an image that
is larger than the image holder, the image holder resizes the image so it
fits but when I write it out I don't get what I see instead I get a cropped
section of the image. So instead of seeing test.jpg as a resized version
of the image I've loaded I get the image cropped at 100%
I have a method like the following (with an mx:Image named imgHolder).
//Encoding
import mx.graphics.codec.JPEGEncoder;
import com.adobe.images.JPGEncoder;
//Local File System
import flash.desktop.*;
import flash.filesystem.File;
private function saveLoadedImage():void {
var loJPGEncoder:JPGEncoder = new JPGEncoder();
var bd: BitmapData =
getBitmapData(mx.core.Application.application.imgHolder); //something not
quite right as it crops and doesn't resize.
var encodedJPG:ByteArray = loJPGEncoder.encode(bd);
var file:File = File.desktopDirectory.resolvePath(test.jpg);
//saves it to the desktop as a file labeled test.jpg
var stream:FileStream = new FileStream();
stream.open( file, FileMode.WRITE );
stream.writeBytes( encodedJPG );
trace(saved.);
}
private function getBitmapData( target : UIComponent ) : BitmapData
{
var bd : BitmapData = new BitmapData( target.width,
target.height );
var m : Matrix = new Matrix();
bd.draw( target, m );
return bd;
}
Any insight? Thanks!

Re: [flexcoders] Re: AMFPHP MySQL Results Object
Thanks Aaron,
I'll see what I can look up on the RemoteObject as well.
CaffeineWabbit,
Thanks for the pointers. I saw that Mike Potter's AMFPHP example also
created a php array instead of using the mysql results object but... I
noticed on the AMFPHP browser page it can actually create a table based on
the recordset that is returned. e.g. the table automatically changes based
on my sql result and it doesn't seem like there's any specific binding to
columns. I'm curious as to how they did that.
In short, I'd like to find a convenient way for the client to parse the
results of a remote sql query.
Thanks all!

Just as a follow up. I verified that using RemoteObject does in fact
return an ArrayCollection as the result, while NetConnection does not
(returns an outdated ResultSet object). Hopefully someone at Adobe could
explain the difference in remoting procedure between the two methods.

Hello again. I did some more reading on this and I think the problem is
with using NetConnection instead of RemoteObject. Apperently, using
NetConnection does not always send the right headers to tell AMFPHP to use
AMF3 encoding, thus it tries to return a ResultSet instead of an
ArrayCollection. You can tell you got a ResultSet if the return object has a
serverInfo property. From what I've read, using RemoteObject is a surefire
way to get the right headers (AMF3) and will guarantee an ArrayCollection is
returned. However, having been accustomed to NetConnection myself, and I am
trying to figure out a way to do this without RemoteObject. Setting
NetConnection.objectEncoding to ObjectEncoding.AMF3 did not help for
some reason. Maybe someone else can chime in on this.
In the mean time, here is a good tutorial on RemoteObject with AMFPHP:

Hi Daniel,
In the PHP code you provided, you can't pass back the raw $results
variable because its not a normal PHP variable - its a resource, which
holds external data and can only be used by special PHP functions (in
this case, the mysql library.)
To pass back the results from your query, you'll first need to extract
the data into a format that can be passed by AMFPHP. Something similar
to the following:
?php
class SimplePerson
{
function getPeople()
{
$mysql = mysql_connect(localhost, root, root);
mysql_select_db( people-test );
$sSQL = SELECT * FROM `tblPeople`;
$results = mysql_query($sSQL);
$queryResults = array();
while($queryOb = mysql_fetch_assoc($results))
$queryResults[] = $queryOb;
return $queryResults;
}
}
?
That'll show up in Flex as an array containing generic objects that
contain your query results.
For more info on resources, this link should help:
http://www.php.net/manual/en/language.types.resource.php
Hope this helps!

Re: [flexcoders] AMFPHP MySQL Results Object
Thanks Aaron!
I'm still a bit unsure about referencing the individual items then.
after I have collection... how do I actually access each row/column?
I tried to find out the length or number of rows by going
collection.length... it didn't seem to like that at all.

I always set the return result as Object in my handler then type it as

Also notice that I used ArrayCollection. If I remember correctly, record
sets get returned as an ArrayCollection. If I am mistaken, try the above
with a standard Array.

Re: RE: [flexcoders] Photo print service
Hi Mike,
About the memory issues and images how did you get it to release the memory
in Flex?
I noticed that when we try to load images to an mx:Image object in a loop
containing this:
// imgObj already defined as an mxml Image object
for (var i:int = 0; i 5; i++) {
imgObj.source = null; // This doesn't clear the memory... but the docs say
it should...
imgObj.source = ImageFileArray[i].path;
}
The memory taken by each image is not freed can you shed some light as
to why it doesn't release it?
Thanks!

Sortof? When developing HP Print Studio (http://www.hp.com/printstudio) we
ran into this very same issue, but instead of photos we had multiple high
resolution template assets that were only loaded when a printjob was
requested. Given our use cases (most users don't have duplex printers) we
didn't actually have to do multi-page printing so it's not quite what you're
looking for, but the implementation might be similar.
Basically what you want to create is a temporary sandbox object that
exists on the displaylist (so content is rendered) but doesn't actually show
anything (height and width = 0). Within that object you compose your print
pages, paying special attention to keep track of how many images are
currently loading using event listeners- in particular the load complete
event. Once everything's signaled that it's ready you print, and in the
meantime put up a progress bar popup of some kind.
You might also be able to do delayed page instantiation, that is: create a
page, wait for it to finish, add it to the print job, destroy it, move to
the next page. This will give you better memory management overall (I think)
since you don't have to load your entire photo album into ram before
printing.
Also, be careful about your image sizes: Images in memory suck up a LOT of
ram.

*Subject:* [flexcoders] Photo print service
Hi All,
I have a requirement to build a photo print service in Flex. The EU will
view a gallery of image thumbnails (TileList) and have the option to print
one photo or the entire contents of the gallery. Photo print options would
be fit to page, 5x7, 8x10 ect…
Searching the web, viewing the docs and examples using the FlexPrintJob
from my understanding I can print images but they must be loaded (drawn) in
flex prior, is this true?
For a single photo print job this is fine as I can have the print page
display the selected image size prior to sending the print job. However, I
also want to allow the EU to select an entire photo folder and print the
contents all to say 5x7, is this possible?
Does anyone know of any examples or sample code?
Any comments much appreciated.
Thanks,
Greg

[flexcoders] Flex Amazon S3 Access Control List / ACL
Hi All,
I've been playing around with the awss3lib (
http://www.code.google.com/awss3lib ) and looking at the documentation for
Amazon's S3 ( http://docs.amazonwebservices.com/AmazonS3/2006-03-01/ )and I
was wondering if anyone managed to get the ACL working with the awss3lib?
If so, can you explain how you did it?
The documentation says that we need to add a header
x-amz-acl:{*private, *public-read,
etc} to the PUT request but I can't seem to do it properly. I figured that I
need to modify the authorization string but the one that the awss3lib
doesn't seem to have headers. e.g. instead of Content-Type: text/plain
it's just encoding text/plain and yet the request header has the full
thing (Content-Type: text/plain). I tried adding x-amz-acl:public-read to
the request header, and then to the authorization string but it comes back
as an error 2038.
Any help would be appreciated!
Thanks!
