Image preview in Flex - apache-flex

I am working on an image management application. We have an Adobe AIR client talking to a WAMP server. The MySQL DB stores the images as blobs.
We have an image search feature. Upon searching, I am displaying the results as XMLList in a popup window and provided a download button. Downloads work fine. I also want to add a preview button to the popup.
Please let me know how can I code this. Without having the file on the client, I cannot preview. But when I use save() method, the os dialog opens up. Anything to be done on the PHP side?
Please help.
Regards
Jad.

Don't you mean to display an Image? Wouldn't the normal work? Of course, for performance issues, your PHP code must render smaller images (thumbnails).
Correct me if wrongly understood your question. :(

How to resolve the Blurness issue in print Preview of UWP?

I am familiar with the data grid in the UWP plat form. we tried to provide the support for printing the results in sheets. we have faced the hurdles while we print the content. In the print preview panel the content looks like blurry to the view, but in the printed sheet the contents look like normal. could your share your ideas to resolve this.
Thanks in advance for your updates.
It seems it is by design.
In UWP, we use the PrintManager to inform Windows that an application wishes to participate in printing.
When we run the ShowPrintUIAsync() method, it will run the "PrintDialog.exe" that the print Preview page will be shown.
We can use the "Inspect" to test the content of the print Preview page. From the following image, we can see the content is a Image control that render by the XAML.
For the performance, it does not render as clear as the printting result. We can not change that.
If you do want this feature, you are welcome to ask on UserVoice.

How to browse image make it appear in Image control

My Scenario,
I'm using Visual Studio 2005. In my website Page I'm trying to browse a image and display in image control and then i need to insert to Database, But I'm Unable to bring the image to control.
1.Browse image
2.View in the control and then insert in Database.
This What I want and I'm searching for code.
This is difficult to do on the client side without sending the image to the server at all without using a technology like Flash to display the preview of the image before uploading it.
If you wish to use Flash, then there is a donationware component called Agile Uploader that even has a jQuery plugin available that allows you to display a preview of the image wherever you like before uploading, as well as being able to resize the image on the client side first, so you don't have users uploading massive files. It's well worth a look.

You could try wkhtmltoimage, which looks like it has some Windows support. Once its installed, you just run wkhtmltoimage http://www.site.com site.screenshot.png.

How to edit images using javascript in real time and save the edited image on the server?

Is it possible to edit images using a javascript library and then send the edited image to the server for saving.
Edits will be in real time, means the user can see the edit result in the same time he is editing without the need to refresh the page.
I want a javascript library to do some edits on an image on a webpage 'such as crop, resize, rotate,...' and send send the edited result to the server.
How this can be done or if there any smart work around to something like this.
The libraries mentioned don't seem to be fully cross browser. As far as I know there is no fully cross browser compliant way to edit pixel data on the client.
The current best approach would be to do these manipulations on the server. You can still do this real time using a web service.
As an example see the image editor in TinyMCE which supports crop, rotate, resize, flip, all from the client without a page refresh.
Pixastic is an image manipulation library; once you've modified the image, some sort of post back / upload call from the script will be able to upload the image provided you've implemented the needed functionality to do so.
An incomplete list to be sure, but these are two that come to mind which allow you do a wide variety of editing on the client side and push back to the server.
PIxastic
AIE
And there are numerous less complete image editing tools for simply cropping or adjusting contrast as well.
jcrop is what you are looking for .

Multiple file upload with preview

Is there any good control or plug-in for uploading multiple photos with preview? As far as I understand it is impossible to preview photo on local computer using just JavaScript. So it has to use Flash or Java.
Thanks, also, I use ASP.NET.
Wait, do you mean show it in a browser window before starting the upload? So does the file have a URI? (Hint: file:///c/users/public/somefile.png is a URI) You can always just link it into an image tag on their browser session.
Now, will a browser let you link a file:/// for image? That I've not tried, but you should; at least you'll learn something from it when you do try.
But using this, there's no reason you can't use a lightbox style image viewer with the local URI.
You could also make use of silverlight 4. If you're looking for something already written you might try using the upload control from gallery which much require some hackery or if you have money to burn then telerik have an upload control but I don't believe it supports previews. This http://www.aurigma.com/Products/ImageUploader/ also looks nifty.
