    <p>I'm not quite sure what you mean bye "other side" and "native language".</p> <p>But, you can send canvas images to a server using AJAX.</p> <p>The server receives the canvas image as base64 encoded image data.</p> <p>For example, assume:</p> <ol> <li><p>You’re sending the image to a php server (yourOtherSide.php) – but of course this could be any server that accepts ajax posts.</p></li> <li><p>You have a reference to the canvas element holding your frame: canvas</p></li> <li><p>Your ajax payload contains an id number of the frame being sent (ID) and the image data (imgData).</p></li> <li><p>(optionally) You are getting some response back from the server—even if it’s just “OK”: anyReturnedStuff</p></li> </ol> <p>Then your ajax post would be:</p> <pre><code>$.post(“yourOtherSide.php”, { ID:yourFrame ID, imgData: canvas.toDataURL(‘image/jpeg’) }) .done( function(anyReturnedStuff){ console.log(anyReturnedStuff); } ); </code></pre> <p><strong>[Edited to include server-side creation of images from the ajax post]</strong></p> <p>These code samples will receive the ajax base64 imageData and create an image for you to process with your c-image-processing-library.</p> <p>If your're using a PHP server:</p> <pre><code>$img = imagecreatefromstring(base64_decode($imageData)); // and process $img with your image library here </code></pre> <p>or if you're using asp.net:</p> <pre><code>byte[] byteArray = System.Convert.FromBase64String(imageData); Image image; using(MemoryStream s=new MemoryStream(byteArray){ image=Image.FromStream(ms); // and process image with your image library here } </code></pre>

    1. COThanks,markE. The other side is a c library which does the actual processing on the images. Do suggest a way how i can send these frames / frames data to the c- library.

    2. COThe result of ctx.getImageData(sx,sy,w,h).data is a Uint8ClampedArray Which is a binary string where each byte is one of the colors/alpha of a pixel. Sending the data to the sever you need to send an octet-stream header. Let the web workers send the data. There is a possibility to let the web worker be the owner of the buffer. So no coping is necessary.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
