View 1 RepliesDoes anyone know a way to crop a SWF like you would crop an image in Photoshop? I'm building a Flash Banners application in my Flash portfolio website and I'm loading a SWF using addChild via a URL loader object. There is no way to mask the outsides of the SWF because addChild puts the SWF at the front of the display list so the masks would just show up anyway and the masks will just be huge white sheets that will look dreadful. I need to LITERALLY crop the SWF down to 550 X 325 pixels.

View 1 RepliesI've been following this tutorial to crop images in flex: [URL]
At the heart of its cropping is using a method called "copyPixels". However, this method takes as one of its arguments a rectangular shape for its crop region. Are there other strategies I can use to crop it not using a rectangle.
I am going after letting the user specify the region that should be cropped using a series of points.
I have a flex mobile application that I am working on that I am having issues with selecting an image from roll/taking a picture. My application is not tabbed, however one part of it contains a Tabbed View Navigator with tabs across the bottom. Within one of those tabs, I have the ability to upload an image to a webservice that I have created. However, when I select an image or take the picture, it pops back out to the initial splash screen and the application restarts. If I use the component standalone (outside of the tabbed view navigator) it selects the image and uploads without any problem.

I have the code to copy parts of a huge loaded BitmapData to a target BitmapData that is just the size that I can display. I think I have set the scroll bars of an enclosing Canvas to show the size of the larger image and allow the user to scroll. Now I need to put the selected pixels on the screen. When I try to add a Bitmap component as a child of the Canvas, it get an error because Bitmap is not a UIComponent. What's the best way to put the target BitmapData into an Image component?

View 1 RepliesI'm trying to write a little flex app that has a paint/canvas type feature to draw an image, which I then want to post to a rails server side. I'm following the post here, but can't get as far as he did due to the following error: NoMethodError (undefined method `rewind' for #):I googled that and found this which says the problem is due to an empty filename, but I thought I had that from the example. However, I altered the example to simplify the post by reducing the form parameters, but I could have easily messed something up since I really don't know what I'm doing with this multipart form content. I was hoping to at least log the request params, but unfortunately I can't, since it's failing before being routed and due to my inexperience with rails. I'll ask that in a separate question and hopefully be able to edit this question with the request params.

View 1 RepliesI'm running a web application built on Seam. I would like to have an image upload + crop component. Preferably on client side, so the image uploaded to the server would be the result of the crop. I read this can be made with Flash 10. I was thinking flex is also a possibility. Does anyone has good hints to give me, what component to choose or what is the best way to connect the backing bean I have with the flash/flex?

View 1 RepliesI just started working with bitmaps and I do not get them at all, I've read the entire page adobe has on bitmap and bitmapdata. I've got this code together but all it does is displays a white rectangle and not my image.
ActionScript Code:
package {
import flash.display.MovieClip;
import flash.display.Loader;
import flash.display.Bitmap;
import flash.display.BitmapData;
This code should load the image into the bitmap (which works), then crop it with the rectangle (which just crops the fill from the bitmapdata)

View 4 RepliesI've been playing with the Jpeg encoder now for a while and haven't come much further than just realising how to turn an image into a ByteArray of numbers. The code below is incredibly useful at turning a movieclip on the stage into a Jpeg and downloading it to the user. Unfortunately I need to amend the Bytearray first with a crop tool before creating the jpeg. e.g. delete the array value if the image is outside of the rectangle? And a rotate tool, e.g. all the values in the array switch places 90 degrees!? (the X and Y values switch over).Also it downloads to the user, but I need it to save onto the server so I can keep using it in flash, before then emailing the jpeg to a known email address.
(E.g. if a 10px x 10px bitmap, would have 100 values in the array, to crop it into a 5 x 5 image, I would delete array entries
where X < 2 and X > 7
and Y < 2 and Y> 7.
Or to rotate it, X for 1st pixel becomes the Y for the 1st pixel and vice versa)....

import com.adobe.images.JPGEncoder;
import flash.net.URLRequest;
import flash.display.BitmapData;
import flash.utils.ByteArray;
import flash.net.URLLoader;

I am trying to write a flash app that will allow a user to select various regions of an image, similar to that of the selection tool in photoshop where a square region can be stretched and selected.
Would anyone have any ideas or tips for me that could get me going in the right direction? I have been researching for tools to help me write this but haven't been able to find anything useful..
I would like to make a very simple (well, looks simple anyway) image gallery, like Ilyas da Pom's at [URL]..
I want the image part to scale to fit each image dynamically. I'm a brand-spanking new Flash novice, and any guidance would help really; this is just a tiny little personal project, not to be used anywhere commercially.

View 2 RepliesIn 90% of the example projects I see for ActionScript / Flex I notice the following two coding conventions: 1) private member variables with getters/setters start with an underscore as in "_credentials" and 2) interfaces start with the letter "I" as in "ISessionInfo" Coming from the Java world, I find both of these conventions unnecessary and annoying. I am about to start a new Flex project and was planning on NOT following these conventions unless they are truly are widespread, standard conventions in the Actionscript/Flex world.

I'm developing a flash app by using free Flex SDK and text editor and compiling in command line.
I want to use VGroup or HGroup in my actionscript to manage positions of DisplayObjects.[code]...
I have a UI component that, for various reasons, I have to construct programatically. The component is a table of radio buttons grouped by column.Right now, I'm constructing the column groups like so:
private function createGroupsForItemList(items: XMLList): void {
for each (var item: XML in items) {
var rbGroup: RadioButtonGroup = new RadioButtonGroup();
groups[item.@level.toString()] = rbGroup;
}
}
I'm trying to associate the RadioButton instances with the column groups like so:
private function createValueControl(item: XML): UIComponent {
var control: RadioButton = new RadioButton();
control.label = "";
[code]...
I can see in the debugger that the control has an association to the group:
control.group == groups[item.@level.toString()]
However, I can see equally that the group does not know anything about the control:
group.radioButtons.length == 0
I imagine that this is because the setter for group in RadioButton is a dumb setter; all it does is copy to the variable, which doesn't do the magic that groupName does. However, I can't seem to find the value I should use to set the RadioButton.groupName property correctly.So, in short, I'm stumped on how to get these bits to talk to each other. How do I do this?
-- EDIT -- It turns out that I can have the groups created and associated simply by setting the groupName property, but I can't get at the group to set up a selection listener; the group is NULL immediately after the setting process, which means that the second line below throws the Flex equivalent of an NPE:
control.groupName = groupNameForLevel(item);
control.group.addEventListener(Event.SELECT, updateSelection);
What it says on the tin: I have an XMLList, and I want to find where in it a particular XML item falls. First index is good enough for my purposes. Note that I have no problem writing a function to do this by hand... but I was hoping that the API has something buried somewhere that'll do it for me. I didn't see it, though.
