kandi X-RAY | dimensions Summary
Pass an IO object to the Dimensions method to extend it with the Dimensions::IO module and transparently detect its dimensions and orientation as it is read. Once the IO has been sufficiently read, its width, height and angle methods will return non-nil values (assuming its contents are an image).

QUESTION
I Am having the following data in my SSAS cube.
My need is to get the value of the measure based on two conditions with two different dimensions using the
MDX.
In this example data, I need to get the
Reseller Sales Amountvalue where the value ofTitledimension is equal to Sales Representative and the value of theGenderdimension is equal to Male condition.
I have tried to achieve the requirement with the Case statement and IIF() function available in the MDX but it is not working.
Please find the queries I have tried with different functions.
Using Case statement:

Answered 2021-Aug-04 at 09:18I'm not sure what you're using to code, but in order to set it in Android Studio, open the manifest of your project and under the "activity" section, put android:exported="true"(or false if that is what you prefer). I have attached an example.
QUESTION
I am currently trying to figure a way to return a mutidimensional array (of doubles) from a shared library in C to python and make it an np.array. My current approach looks like this:
shared library ("utils.c")
...ANSWER
Answered 2022-Feb-21 at 10:17First of all, a scoped C array allocated on the stack (like in somefunction) must never be returned by a function. The space of the stack will be reused by other function like the one of CPython for example. The returned array must be allocated on the heap instead.
Moreover, writing a function working with Numpy arrays using ctypes is pretty cumbersome. As you found out, you need to pass the full shape in parameter. But the thing is you also need to pass the strides for each dimension and for each input arrays in parameter of the function since they may not be contiguous in memory (for example np.transpose change this). That being said, we can assume that the input array is contiguous for sake of performance and sanity. This can be enforced with np.ascontiguousarray. The pointer of the views a and b can be extracted using numpy.ctypeslib.as_ctypes, but hopefully ctype can do that automatically. Furthermore, the returned array is currently a C pointer and not a Numpy array. Thus, you need to create a Numpy array with the right shape and strides from it numpy.ctypeslib.as_array. Because the resulting shape is not known from the caller, you need to retrieve it from the callee function using several integer pointers (one per dimension). In the end, this results in a pretty-big ugly highly-bug-prone code (which will often silently crash if anything goes wrong not to mention the possible memory leaks if you do not pay attention to that). You can use Cython to do most of this work for you.
Assuming you do not want to use Cython or you cannot, here is an example code with ctypes:

I have the following code (also pasted below), where I want to make a layout of two columns. In the first one I am putting two images, and in the second displaying some text.
In the first column, I want to have the first image with width:70% and the second one with position:absolute on it. The final result should be like this
As you see the second image partially located in first one in every screens above to 768px.
I can partially locate second image on first one, but that is not dynamic, if you change screen dimensions you can see how that collapse.
But no matter how hard I try, I can not achieve this result.

Answered 2022-Feb-07 at 08:19With the code below, you have the structure that you want. All you have to do is to play with the width, height, etc to make exactly what you need.
QUESTION
While working on a react native project I stumbled upon this error:
JSON value of "90vh" of type NSString cannot be converted to a ABI44_0_0YGValue. Did you forget the % or pt suffix?
What does ABI44_0_0YGValue mean? I have tried the pt suffix but the same error still appears. What could be the problem?
I am using styled components to add the width and height value to different elements:
...ANSWER
Answered 2022-Jan-12 at 05:53All dimensions in React Native are unitless, and represent density-independent pixels.
In other words, the error is being thrown because React Native is looking for a Number type, not a string. Unlike CSS for the web, the "vh" and "px" suffixes are meaningless here.

QUESTION
I am trying to display rich links in a SwiftUI List and no matter what I try, I can't seem to be able to change the size of the link view (UIViewRepresentable) on screen.
Is there a minimum size for a particular link? And how can I get it. Adding .aspectRatio and clipped() will respect size but the link is heavily clipped. Not sure why the link will not adjust aspectRatio to fit view.
Some of the following code is sourced from the following tutorial: https://www.appcoda.com/linkpresentation-framework/
I am using the following UIViewRepresentable for the LinkView:
...ANSWER
Answered 2021-Dec-29 at 13:24The solution that worked for me was subclassing the linkView overriding the intrinsic content size. Thanks to user1046037's comment, using super.intrinsicContentSize.height will enable it to work dynamically.
QUESTION
I have three lists (really columns in a pandas dataframe) one with data of interest, one with x array coordinates, and one with y array coordinates. All lists are the same length and their order in the list associated with the coordinates (so L1: "Apple" coincides with L2:"1", and L3:"A"). I would like to make an array with the dimensions provided by the two coordinate lists with data from the data list. What is the best way to do this?
The expected output would be in the form of a numpy array or something like:

QUESTION
I'm currently working on creating a subtype of AbstractArray in Julia, which allows you to store a vector in addition to an Array itself. You can think of it as the column "names", with element types as a subtype of AbstractFloat. Hence, it has some similarities to the NamedArray.jl package, but restricts to only assigning the columns with Floats (in case of matrices).
The struct that I've created so far (following the guide to create a subtype of AbstractArray) is defined as follows:
ANSWER
Answered 2021-Nov-09 at 21:09Yes, the implementation of matrix multiplication will vary depending upon your array type. The builtin Array will use BLAS, whereas your custom fooArray will use a generic implementation, and due to the non-associativity of floating point arithmetic, these different approaches will indeed yield different values — and note that they may be different from the ground truth, even for the builtin Arrays!
