Github repository | Github issues | Documentation. ️ Please note: work in progress, things will change and/or break! ️. This python package provides consistent and user-friendly functions for tiling/patching and subsequent merging of NumPy arrays. Such tiling is often required for various heavy image-processing tasks such as semantic segmentation in deep learning, especially in domains where images do not fit into GPU memory (e.g., hyperspectral satellite images, whole slide images, videos, tomography data). Please see Quick start section. If you want to use tiler interactively, I highly recommend napari and napari-tiler plugin.

QUESTION
I'm stuck trying to create an animation of a contourf representation of concentration over a map, the main code I've been using is:
...ANSWER
Answered 2020-Oct-27 at 17:38A sequence of patches is stored in collections. Every time update is called a new patch is added. Therefore, you will need to clear previous patches by incorporating the following line in the update function. Moreover, you want to have blit=False because the axes are being modified.
QUESTION
I am trying to plot source and receiver points on a map in cartopy, where I zoom into the map based on the locations of the source and receiver. For each combination of source and receiver, I have a new map, with a new extent. I would like to find a way where I can download the map image once, and then just change the extent each time so I don't have to load in the map image every time (I have to make thousands of these). All of the events take place in one country, so I am hoping to just download the map of the whole country and then just change the extent for each loop through.
I have actually partially solved this problem, but I ran into an issue with the grid. Initially, I first set the extent to the whole country, loaded in the image, and then saved it. Then I could reset the extent for each source receiver pair, plot the two points, and then save the image. Afterwards, I just needed to erase each of the two points, and then I could set the extent another time.
However, once I added in the grid with latitude and longitude labels, I ran into an issue. I can't erase the grid and labels after each iteration, so they end up just layering on top of eachother, and the labels start to move all over the figure. The only way I can get rid of the grid is by clearing the axis, but that erases the map image.
My question: is there a way to just erase a gridliner object (not hide the labels and grid but actually delete)? If not, is there a different way to load in the image in the beginning so I can clear the axis each time, but not have to completely reload in a new tiler?

I am a newbie to gstreamer and I would like to know if we have to create source and sink pads for convert like video convert in a pipeline. I have a pipeline like this
...ANSWER
Answered 2019-Dec-19 at 07:45Your first example fails because data.source element is actually never linked to data.convert element. Since both elements have static pads you need to "manually" create them and link them before setting pipeline to GST_STATE_PLAYING:
QUESTION
I'm still relatively new to Pyspark. I use version 2.1.0. I'm trying to clean some data on a much larger data set. I've successfully used several techniques such as "dropDuplicates" along with subsets and sql functions (distinct, count etc).
I then came across dropna, which I thought might simplify matters. But I do not understand why rows 3 and 6 are still present after using dropna. For example:
...ANSWER
Answered 2017-Apr-08 at 16:50First thing is, na creates a new dataframe, so assign it to new df name, and 2nd, specify subset to check which columns to check for null values
QUESTION
Let's start by considering this simple snippet:
...ANSWER
Answered 2019-Oct-25 at 12:37In the first pass a single tile is rendered to a framebuffer, which has exactly the size of the tile. gl_FragCoord.xy is (0,0) at the bottom left of the tile. uv = (0,0) has to be at the bottom left of the window and uv = (1, 1) at the top right of the window. To calculate the the uv coordinate in respect to the window, you've to add the offset of the tile to gl_FragCoord.xy and to divide by the size of the window:

So what I'm trying to do is load satellite images from an SQL table and wrap them around a sphere to create a globe. I know I've got loading the images covered, I'm just not sure how to make my shader display the images in the correct orientation.
I've gone to the Unity Forums as well as checked out this code from the Unity Docs.
Using the linked shader code and the help I received on the forums, here's the code I've ended up with:
...ANSWER
Answered 2019-Sep-23 at 21:26If you can index into the array of photos such that you effectively have an equirectangular projection of the globe, you could try using a modified form of the shader code by Farfarer from the Unity forums copied and modified slightly below:

QUESTION
I am making an interactive tool with tkinter, and want to map a masked data set against the longitude and latitude (masking based on selection in list boxes) with the help of pcolor. I want a colorbar next to the map. The idea is that if you click the 'select' button that the map will be shown and that if you click the button again that the map is updated.
I tried to use matshow instead of pcolor in order to see if the plotting worked or not. It worked, however I did not work when I used crs=ccrs.PlateCarree(). For the update part I tried to make a new canvas.
...ANSWER
Answered 2019-Apr-11 at 14:54I did it differently and now the plotting of the colorbar works. This is what I did.
QUESTION
So I am trying to create a web page that is an image of a tree (like a tree of life kinda, but much smaller) that you can zoom to see a more detailed view of the branches and as you zoom Text and links that fixed to certain parts of the tree (like the end of a certain branch for example) come in to view. I know there is tiler apis like the Google Maps Api or MapTiler but I'm just not sure if these will work for what I am trying to do. What I am trying to do is make a user interface similar to OneZoom's (www.onezoom.org).
Thanks for the help. Cheers.
