javascript - Scaling canvas together with elements over it -

-

I want to get some ideas about applying it.

Here's the sketch:

sketch < P> Description: I have a view (canvas on the sketch) and we say that the 2 panel canvas gives the situation with DIV, the panel is outside of this DIV and some element elements of this DIV All the elements with the status are draggable. Every element has a div with the inner canvas.

Problem: I need to implement the zoom of this canvas in any way. I am zooming the canvas (it has a grid drawn on it) and the element is also zooming. It can be scaling (I know about quality after the scaling bitmap, it is acceptable in my case). The only problem is that I do not really know how to scale both canvas and independent elements, which are on it, that our illusion is that visual scaling is there. Hope you have received the idea of ​​what I am trying to do.

If your target browser performs CSS3 conversions, you can use your floating divs Change the style to transform: scale (1.5.1.5) .

Note: You probably want to wrap the canvas and full divas to div to overflow: hidden so that you can only show things in that area.

mysql - BLOB/TEXT column 'value' used in key specification without a key length -

-
I have developed an extension which works up to 1.6 on Magren (I'm trying Enterprise Edition, And I think the community is the same problem, because it is the same code). In my install script, I see the $ installer-> gt; CreateEntityTables ($ this- & gt; getTable ('alphanum / info')); The installation is done until it is not in the _text unit table. It crashed there! It turns out that when I log in to SQL and run it via PHPmyadmin, then this error is: Blob / Text column 'value' is used without the key 'key' . I saw the code there, and this is what is trying to create an index on the value column: -> addIndex ($ this- & gt; getIdxName ($ eavTableName, array ( 'attribute_id array (' attribute_id ',' value ')) - & gt; addIndex ($ this- & gt; getIdxName ($ eavTableName, array (' entity_type_id ' , 'Value')), array ('entity_type_id', 'value')) If there is no if statement is n...

memcached - Django cache performance -

-
We are now using Redis for in-memory cache for our Django application (we used the first memcatch The difference in performance is no big, and we're using Redis because the disc dump feature). The problem is that Django cache's performance in my view - terrible, we have a view with 102 cache hits (no miss), and it has 81 ms (only the cash part, which is with the DJBugBug toolbar Is measured). In my opinion - this is a very long time, I know, asking for a question for DB can be 10x more (or 100x) time, but that is also not good with cash performance of that fact. We are running radis (and the first memacatch) on different hosts, connected to the local network with other servers. Is there a way to maximize cache performance in Django? Instead of displaying problem cache, there is a possibility of the number of items to be received for each page 102 Cash calls mean long time lost due to network latency. With full control of the code, you may be able to fix it with m...
