Given two polygons:

    POLYGON((1 0, 1 8, 6 4, 1 0))
    POLYGON((4 1, 3 5, 4 9, 9 5, 4 1),(4 5, 5 7, 6 7, 4 4, 4 5))

How can I calculate the union (combined polygon)?

[![enter image description here][1]][1]

[Dave&#39;s example][2] uses SQL server to produce the union, but I need to accomplish the same in code. I&#39;m looking for a mathematical formula or code example in any language that exposes the actual math. I am attempting to produce maps that combine countries dynamically into regions.

I&#39;m using this code:

    s = line.match( /ABCD(\d{4})/ ).values_at( 1 )[0] 


To extract numbers from strings like:

    ABCD1235
    ABCD1236

etc. 

It works, but I wonder what other alternative I have to to this in Ruby?

When writing a print stylesheet, is there a way to ensure that an image is always only on a single page, instead of spanning multiple pages. The images much smaller than the page, but based on the document flow, they end up at the bottom of the page and get split. An example of the behavior I&#39;m seeing is below:

    Page 1 |                    |
           |  (text text text)  |
           |  (text text text)  |
           |  ________________  |
           | | Top of image   | |
           |____________________|
           ------page break------
            ____________________
    Page 2 | | Rest of image  | |
           | |________________| |
           |         …          |

What I&#39;d like

    Page 1 |                    |
           |  (text text text)  |
           |  (text text text)  |
           |                    |
           |                    |
           |____________________|
           ------page break------
            ____________________
    Page 2 |  ________________  |
           | | Full image     | |
           | |                | |
           | |________________| |

Is there a public API from some big company to get my public ip from within a program? 

I&#39;ve found `http://ip-address.domaintools.com/myip.xml`, which is exactly what I want, but unfortunately it blocks Python&#39;s `urllib` as well as many other http libraries, unless you spoof user-agent (anything doing that can&#39;t be called an API at all).

The problem is that I need this data for some potentially open source library, so we have to play by the rules. I also know that I can just do smth like `print $_SERVER[REMOTE_ADDR]`, but I don&#39;t want to server traffic to everyone using my library.

So, is there something like the URL above, but real API, that allows robots?

Getting my public IP via API

I&#39;m at the point where I need to write unit tests for a REST API written using CakePHP 1.3. The API supports GET, POST and PUT requests for querying and manipulating data.

Is there any established way to test the correct input/output of an API simulating an HTTP request, using **fixtures**? I do not want to run actual POST/PUT requests against the live (dev) database. How can I best mock out the system to use temporary models, yet test the rest of the stack as-is?

----------

Testing GET requests is easy enough with [controller tests][1]. However, for data manipulation the API uses HTTP headers quite extensively and also parses raw XML and JSON POST/PUT data. The controller unit test methods only mock POST data by setting `$this-&gt;data` in the controller, which does not allow me to properly test the API.

**Note:** Files can be of any type...

Multiple file upload in php

I&#39;m trying to embrace jQuery 100% with it&#39;s simple and elegant API but I&#39;ve run into an inconsistency between the API and straight-up HTML that I can&#39;t quite figure out.

I have an AJAX file uploader script (which functions correctly) that I want to run each time the file input value changes.  Here&#39;s my working code:

    &lt;input type=&quot;file&quot; size=&quot;45&quot; name=&quot;imageFile&quot; id=&quot;imageFile&quot; onchange=&quot;uploadFile()&quot;&gt;

When I convert the `onchange` event to a jQuery implementation:

    $(&#39;#imageFile&#39;).change(function(){ uploadFile(); });

the result isn&#39;t the same.  With the `onchange` attribute the `uploadFile()` function is called anytime the value is changed as is expected.  But with the jQuery API `.change()` event handler, the event only fires the first time a value is change.  Any value change after that is ignored.  This seems wrong to me but surely this can&#39;t be an oversight by jQuery, right?

Has anyone else encountered the same issue and do you have a workaround or solution to the problem other than what I&#39;ve described above?  

jQuery change method on input type=&quot;file&quot;

I&#39;m trying to make ajax file upload . I read that it is not possible to do that without using `iframe` .   
I wrote :

    &lt;iframe id=&quot;uploadTrg&quot; name=&quot;uploadTrg&quot; height=&quot;0&quot; width=&quot;0&quot; frameborder=&quot;0&quot; scrolling=&quot;yes&quot;&gt;&lt;/iframe&gt;
    &lt;form id=&quot;myForm&quot; action=&quot;file-component&quot; method=&quot;post&quot; enctype=&quot;multipart/form-data&quot;  target=&quot;uploadTrg&quot;&gt;
    File: &lt;input type=&quot;file&quot; name=&quot;file&quot;&gt;
    &lt;input type=&quot;submit&quot; value=&quot;Submit&quot; id=&quot;submitBtn&quot;/&gt;
    &lt;/form&gt;

and using jquery form plugin : 

    $(&#39;#myForm&#39;).ajaxForm({
        dataType:  &#39;json&#39;,
        success:   function(data){
            alert(data.toSource());
        }
    });

**The Result :**  

the file is uploaded successfully and I can see the uploaded file , but a dialog box appears :  

![alt text][1]  


since I send back a json result to display the file name + size etc ..

**My Question :**
How can I use the iFrame to be able to make &quot; ajax file upload&quot;.

Note:


 1. I don&#39;t prefer to use special plugin to upload file , if there is more appropriate/easier  solutions.
 2. I use jsp/servlets as a server-side language .. but I think it does not make sense which language I use .

Thanks

How to make Asynchronous(AJAX) File Upload using iframe?

i am using this code to upload files(images to a folder)

    &lt;form action=&#39;&#39; method=&#39;POST&#39; enctype=&#39;multipart/form-data&#39;&gt;
    &lt;input type=&#39;file&#39; name=&#39;userFile&#39;&gt;&lt;br&gt;

    $target_Path = $target_Path.basename( $_FILES[&#39;userFile&#39;][&#39;name&#39;] );
    move_uploaded_file( $_FILES[&#39;userFile&#39;][&#39;tmp_name&#39;], $target_Path );
    ?&gt;

when the file(image) is saved at the specified path... WHAT if i want to save the file with some desired name....

i have tried replacing THIS

    $target_Path = $target_Path.basename( $_FILES[&#39;userFile&#39;][&#39;name&#39;] );
WITH THIS

    $target_Path = $target_Path.basename( &quot;myFile.png&quot; );
BUT it&#39;s not working



How to upload &amp; Save Files with Desired name

I have WampServer 2 installed on my Windows 7 computer. I&#39;m using Apache 2.2.11 and PHP 5.2.11. When I attempt to upload any file from a form, it seems to upload, but in PHP, the `$_FILES` array is empty. There is no file in the `c:\wamp\tmp` folder. I have configured `php.ini` to allow file uploads and such. The `tmp` folder has read/write privileges for the current user. I&#39;m stumped.

**HTML:**

    &lt;html&gt;
    &lt;head&gt;
    	&lt;meta http-equiv=&quot;Content-Type&quot; content=&quot;text/html; charset=utf-8&quot; /&gt;
    &lt;/head&gt;
    &lt;body&gt;
        &lt;form enctype=&quot;multipart/form-data&quot; action=&quot;vanilla-upload.php&quot; method=&quot;POST&quot;&gt;
            Choose a file to upload: &lt;input name=&quot;uploadedfile&quot; type=&quot;file&quot; /&gt;&lt;br /&gt;
            &lt;input type=&quot;submit&quot; value=&quot;Upload File&quot; /&gt;
        &lt;/form&gt;
    &lt;/body&gt;
    &lt;/html&gt;

**PHP:**

    &lt;?php
    echo &#39;file count=&#39;, count($_FILES),&quot;\n&quot;;
    var_dump($_FILES);
    echo &quot;\n&quot;;
    ?&gt;



Why would $_FILES be empty when uploading files to PHP?

I&#39;m writing an API and I&#39;m wanting to handle file uploads from a form `POST`. The markup for the form is nothing too complex:

    &lt;form action=&quot;&quot; method=&quot;post&quot; enctype=&quot;multipart/form-data&quot;&gt;
      &lt;fieldset&gt;
        &lt;input type=&quot;file&quot; name=&quot;image&quot; id=&quot;image&quot; /&gt;
        &lt;input type=&quot;submit&quot; name=&quot;upload&quot; value=&quot;Upload&quot; /&gt;
      &lt;/fieldset&gt;
    &lt;/form&gt;

However, I&#39;m having difficulties understanding how to handle this server-side and send along with a cURL request.

I&#39;m familiar with sending `POST` requests with cURL with a data array, and resources I&#39;ve read on uploading files tell me to prefix the filename with an `@` symbol. But these same resources have a hard-coded file name, e.g.

    $post = array(
        &#39;image&#39; =&gt; &#39;@/path/to/myfile.jpg&#39;,
        ...
    );

Well which file path is this? Where would I find it? Would it be something like `$_FILES[&#39;image&#39;][&#39;tmp_name&#39;]`, in which case my `$post` array should look like this:

    $post = array(
        &#39;image&#39; =&gt; &#39;@&#39; . $_FILES[&#39;image&#39;][&#39;tmp_name&#39;],
        ...
    );

Or am I going about this the wrong way? Any advice would be most appreciated.

**EDIT:** If someone could give me a code snippet of where I would go with the following code snippets then I&#39;d be most grateful. I&#39;m mainly after what I would send as cURL parameters, and a sample of how to use those parameters with the receiving script (let&#39;s call it `curl_receiver.php` for argument&#39;s sake).

I have this web form:

    &lt;form action=&quot;script.php&quot; method=&quot;post&quot; enctype=&quot;multipart/form-data&quot;&gt;
      &lt;fieldset&gt;
        &lt;input type=&quot;file&quot; name=&quot;image /&gt;
        &lt;input type=&quot;submit&quot; name=&quot;upload&quot; value=&quot;Upload&quot; /&gt;
      &lt;/fieldset&gt;
    &lt;/form&gt;

And this would be `script.php`:

    if (isset($_POST[&#39;upload&#39;])) {
        // cURL call would go here
        // my tmp. file would be $_FILES[&#39;image&#39;][&#39;tmp_name&#39;], and
        // the filename would be $_FILES[&#39;image&#39;][&#39;name&#39;]
    }

I am new to iOS and I am trying to upload an Image and a text using &lt;code&gt;multi-part form encoding&lt;/code&gt; in iOS. 

The &lt;code&gt;curl&lt;/code&gt; equivalent is something like this: &lt;code&gt;curl -F &quot;param1=value1&quot; -F &quot;param2=@testimage.jpg&quot; &quot;http://some.ip.address:5000/upload&quot;&lt;/code&gt;

The &lt;code&gt;curl&lt;/code&gt; command above returns the expected correct response in &lt;code&gt;JSON.&lt;/code&gt;

**Problem:** 
I keep getting a HTTP 400 request which means I am doing something wrong while composing the HTTP POST Body. 

**What I Did:**
For some reference, I tried  https://stackoverflow.com/questions/4683559/flickr-api-ios-app-post-size-too-large and https://stackoverflow.com/questions/5422028/objective-c-how-to-upload-image-and-text-using-http-post. But, I keep getting a HTTP 400. 

I tried the &lt;code&gt;ASIHttpRequest&lt;/code&gt; but had a different problem there (the callback never got called). But, I didn&#39;t investigate further on that since I&#39;ve heard the developer has stopped supporting the library: http://allseeing-i.com/[request_release]; 

Could someone please help me out?


ios Upload Image and Text using HTTP POST

I have an URI image file, and I want to reduce its size to upload it. Initial image file size depends from mobile to mobile (can be 2MB as can be 500KB), but I want final size to be about 200KB, so that I can upload it.&lt;br&gt;
From what I read, I have (at least) 2 choices:

- Using *BitmapFactory.Options.inSampleSize*, to subsample original image and get a smaller image;&lt;br&gt;
- Using *Bitmap.compress* to compress the image specifying compression quality.&lt;br&gt;

What&#39;s the best choice?
****
I was thinking to initially resize image width/height until width or height is above 1000px (something like 1024x768 or others), then compress image with decreasing quality until file size is above 200KB. Here&#39;s an example:&lt;br&gt;

    int MAX_IMAGE_SIZE = 200 * 1024; // max final file size
    Bitmap bmpPic = BitmapFactory.decodeFile(fileUri.getPath());
    if ((bmpPic.getWidth() &gt;= 1024) &amp;&amp; (bmpPic.getHeight() &gt;= 1024)) {
        BitmapFactory.Options bmpOptions = new BitmapFactory.Options();
        bmpOptions.inSampleSize = 1;
        while ((bmpPic.getWidth() &gt;= 1024) &amp;&amp; (bmpPic.getHeight() &gt;= 1024)) {
            bmpOptions.inSampleSize++;
            bmpPic = BitmapFactory.decodeFile(fileUri.getPath(), bmpOptions);
        }
        Log.d(TAG, &quot;Resize: &quot; + bmpOptions.inSampleSize);
    }
    int compressQuality = 104; // quality decreasing by 5 every loop. (start from 99)
    int streamLength = MAX_IMAGE_SIZE;
    while (streamLength &gt;= MAX_IMAGE_SIZE) {
        ByteArrayOutputStream bmpStream = new ByteArrayOutputStream();
        compressQuality -= 5;
        Log.d(TAG, &quot;Quality: &quot; + compressQuality);
        bmpPic.compress(Bitmap.CompressFormat.JPEG, compressQuality, bmpStream);
        byte[] bmpPicByteArray = bmpStream.toByteArray();
        streamLength = bmpPicByteArray.length;
        Log.d(TAG, &quot;Size: &quot; + streamLength);
    }
    try {
        FileOutputStream bmpFile = new FileOutputStream(finalPath);
        bmpPic.compress(Bitmap.CompressFormat.JPEG, compressQuality, bmpFile);
        bmpFile.flush();
        bmpFile.close();
    } catch (Exception e) {
        Log.e(TAG, &quot;Error on saving file&quot;);
    }

Is there a better way to do it? Should I try to keep using all 2 methods or only one? Thanks

Android - Reduce image file size

I wanted to know which is the best way to upload image to server without loosing its quality.
I have searched on google found various methods of posting data. But I am not sure which one would be best to upload.
I came across 

 1. Multipart Image Upload. 
 2. Uploading images using byte array
 3. Uploading images using base64 encoded string.

I have tried Base64 encoding it leads me to OOM(Out of memory) if image is too high in resolution.
Any tutorial which tackle this issue would be appreciated. 
Thanks in advance.
