Hi all, I am working on a function to establish the entropy of a distribution. It uses a copula, if any are familiar with that. I need to sum up the values in the array based on which dimensions are "cared about."
Example: Consider the following example...

It would take a bit more time to make it dynamic, and I don't have the time to visualise it..
Also, stop about 3 dimensions.
Like I said, establish which dimensions you need to sum, then hit them one at a time..

I'm trying to solve this flickering problem on the iphone (open gl es game). I have a few images that don't have pow-of-2 dimensions. I'm going to replace them with images with appropriate dimensions... but why do the dimensions need to be powers of two...

Now....
This would have smaller versions created of dimensions 128x64, 64x32, 32x16, 16x8, 8x4, 4x2, 2x1 representative of the image as a whole.
I'm not sure.
Typically, graphics hardware works natively with textures in power-of-2 dimensions.

I've learned that it is a best practice to explicitly specify image dimensions. The browser can then already layout the page while still downloading the images themselves, thereby improving (percieved) page rendering time.
Is this true? And if so, is ...

However, that CSS may be applied as a style directly on the image tag perhaps the logo) I'll place the actual dimensions in the linked CSS file, but this is typically .

Does anybody know a ready-made, reliable way to tell the dimensions (width x height) of a MP4 encoded using the H.264 codec without ffmpeg or similar extensions, in pure PHP?

Hello,
This is not a "programming" question. But I'm sure it's something that is widely known and understood in this community.
I have an image, x, and a much smaller image, y, and I need to convolve the two by multiplying their FFTs. But since they are...

That would be horribly inefficient if you were doing the convolution in the spatial domain, but if you... .
Padding the smaller array (the convolution kernel, y in your case) with zeroes to match the input image size (your matrix x) is the standard approach .

I'm having a hard time picking up how to grab the dimensions of an element with jQuery. Here is my sample code:
$(document).ready(function() { var width = $("#image_1").width(); var height = $("#image_1").height(); document.write(width); document.write...

(That's what just happened to me.)
Updated : You can confirm that the image is added to the DOM by checking the length property of the jQuery object:
var inDOM = ($('#image_1').length... .
You may get 0 for the width and height if the image is not visible .

To preface this, I'm not familiar with OLAP at all, so if the terminology is off, feel free to offer corrections.
I'm reading about OLAP and it seems to be all about trading space for speed, wherein you precalculate (or calculate on demand) and store ...

In OLAP aggregations help in reducing the query response time by having pre-calculated values which would be used by the query usually .

Full disclosure: I'm very new to Ruby.
The following code seems like it should update the para's text with the app's current dimensions as you resize it.
Shoes.app do stack do @para = para end animate 1 do @para.text = "%d x %d" % [ app.width, app.height...

In the mean time, something like this will work.
Your, they are not receiving in the other direction.
I don't know Shoes well, but it looks like it's a problem with changing the app's dimensions.

I know how to get the size (x,y) of an image
Image.FromFile("cat.jpg").Size
BUT that requires loading the image from memory.
When I view the images in Windows Explorer it shows me the size.
How do I access that size? Is it reliable for all images? Does...

If you want to get the image dimensions (width and hight) with out loading the image, you need=rdr.ReadByte(); return (ushort)(hi|lo); }
This is not my code, got this example some time back in code.
