Re: Uploading a user modified image - Adobe LiveCycle 01-06-2009
Hello,I wanted to bring closure to this question and thank those who responded. Two solutions were proposed. One was to use the Snapshot class to capure the image as modified on the screen, and the other was to modify the image on the server using server based tools. I have implemented the second solution using ImageMagick tools, (actually php Imagick, because I like php, but any language's library of ImageMagick tools would have worked). For my application, the solution has the advantage that I...

Re: Uploading a user modified image - Adobe LiveCycle 10-04-2009
Thanks,This is helping to confirm that there is not a specific capability to upload a transformed bitmap from the memory of an application. I just wish someone from Adobe would confirm was we suspect, and provide some indication if this is a limitation that will be corrected. I don't really buy the performance argment as a general argument, but one that might be true for some applications. Personally, I would usually not discard resolution of a customer's image in order to save bandwidth, unless...

Re: Uploading a user modified image - Adobe LiveCycle 10-04-2009
Michael Borbor,The article you mentioned is one of my sources. Let me quote you what he says about uploading an image after it is put through a matrix transform, such as rotation.In the mx.graphics package there is a class called ImageSnapshot and this can be used to capture the bitmapData of you image to print or create a jpeg or png to save. You can event use it to encode a byte stream to send to the server. I am not going to go too deeply into this but will mention that if you used a matrix t...

Re: Uploading a user modified image - Adobe LiveCycle 09-04-2009
run.ryan,Thanks for this suggestion. I think your suggestion would work. So, are you saying that Flex does not offer any way to upload to the server an image that has been modified by the user in the memory of the application? Before embarking on a work-around that requires me to repeat tasks on the server that the user did on the client, I would like to be sure that such duplication is really required. I am surprised that no one from Adobe has weighed in to tell us whether this problem is a res...

Re: Uploading a user modified image - Adobe LiveCycle 08-04-2009
Bob,Thanks for the response, but my question is still unanswered. I am able to rotate images. The following is the code that I use to rotate an image. The two translations are the to make sure that it rotates at center. if (this.photo != null) { var m:Matrix = new Matrix(); var centerX:Number = this.photo.width / 2.0; var centerY:Number = this.photo.height / 2.0; m.translate(-1.0 * centerX, -1 * centerY); var q:Number = event.value * Math.PI / 180; // event.value contains the degrees to rotate m...

Uploading a user modified image - Adobe LiveCycle 06-04-2009
Hello,I have been able to give the user the ability to upload an image file to our server using the FileReference class and related URLRequest class, and a PHP scipt on the server. I have also been able to display the uploaded image by using an , where host/path is the place it was uploaded to. Next, I was able to use matrix transforms to give the user the ability to rotate the displayed image. While I might add other forms of image manipulation in the future, rotation is essential, because peop...
