QUESTION
When I double click the same item or if I go to each composable screen very quickly i receive an error, How do I solve this problem? I tried changing few things but I just can't solve it and I can't find any resources to fix this problem.
Bottom Navigation implementation
...ANSWER
Answered 2022-Mar-06 at 09:39I'm facing the same problem using the latest compose navigation dependency 2.5.0-alpha03.
I don't know why it's happening.
Philip Dukhov is right, you should report this issue.
Here is a dirty workaround :

QUESTION
I am using Perceptual hashing technique to find near-duplicate and exact-duplicate images. The code is working perfectly for finding exact-duplicate images. However, finding near-duplicate and slightly modified images seems to be difficult. As the difference score between their hashing is generally similar to the hashing difference of completely different random images.
To tackle this, I tried to reduce the pixelation of the near-duplicate images to 50x50 pixel and make them black/white, but I still don't have what I need (small difference score).
This is a sample of a near duplicate image pair:
Image 1 (a1.jpg):
Image 2 (b1.jpg):
The difference between the hashing score of these images is : 24
When pixeld (50x50 pixels), they look like this:
rs_a1.jpg
rs_b1.jpg
The hashing difference score of the pixeled images is even bigger! : 26
Below two more examples of near duplicate image pairs as requested by @ann zen:
Pair 1
Pair 2
The code I use to reduce the image size is this :
...ANSWER
Answered 2022-Mar-22 at 12:48Rather than using pixelisation to process the images before finding the difference/similarity between them, simply give them some blur using the cv2.GaussianBlur() method, and then use the cv2.matchTemplate() method to find the similarity between them:
QUESTION
I have an iOS app, since upgrading to Xcode 13, I have noticed some peculiar changes to Tab and Navigation bars. In Xcode 13, there's now this black area on the tab and nav bars and on launching the app, the tab bar is now black as well as the navigation bar. Weird enough, if the view has a scroll or tableview, if I scroll up, the bottom tab bar regains its white color and if I scroll down, the navigation bar regains its white color.
N:B: I already forced light theme from iOS 13 and above:

Answered 2021-Sep-22 at 12:40first of all the problem is cause by unchecking translucent I fixed it by choosing navigation bar appearance from attributes inspector scroll edge it will fix it see this screen shot please
QUESTION
I'm trying to create a flexbox that is both horizontally as vertically scrollable in case its needed. It's kind of a table layout in flexbox. In the picture below you can see the concept that I'm trying to achieve. This works correctly when the viewport is not too small or too short.
We can then resize the viewport. This works correctly for the vertical overflow. A scrollbar appears and we can scroll downwards. This sadly doesn't work correctly horizontally. We also get a scrollbar for the horizontal part. But the yellow rows (with test) are not the full width I need it to be.
...ANSWER
Answered 2022-Mar-19 at 02:36Every red and blue cells have a minimal width (with flex-basis and flex-shrink: 0) but not the yellow.
The yellow are using the largest width possible for them, but the others are going out their container.
In this situation, the simplest way to "fix" it is to set a minimal width to the yellow bars too.

QUESTION
I've built this new ggplot2 geom layer I'm calling geom_triangles (see https://github.com/ctesta01/ggtriangles/) that plots isosceles triangles given aesthetics including x, y, z where z is the height of the triangle and
the base of the isosceles triangle has midpoint (x,y) on the graph.
What I want is for the geom_triangles() layer to automatically provide legend components for the height and width of the triangles, but I am not sure how to do that.
I understand based on this reference that I may need to adjust the draw_key argument in the ggproto StatTriangles object, but I'm not sure how I would do that and can't seem to find examples online of how to do it. I've been looking at the source code in ggplot2 for the draw_key functions, but I'm not sure how I would introduce multiple legend components (one for each of height and width) in a single draw_key argument in the StatTriangles ggproto.
ANSWER
Answered 2022-Jan-30 at 18:08I think you might be slightly overcomplicating things. Ideally, you'd just want a single key drawing method for the whole layer. However, because you're using a Stat to do the majority of calculations, this becomes hairy to implement. In my answer, I'm avoiding this.
Let's say I'd want to use a geom-only implementation of such a layer. I can make the following (simplified) class/constructor pair. Below, I haven't bothered width_scale or height_scale parameters, just for simplicity.
QUESTION
I don't know if this is possible, but I am trying to take the image of a custom outdoor football field layout and have the players' GPS coordinates correspond to the image xand y position. This way, it can be viewed via the app to show the players' current location on the field as a sort of live tracking.
I have also looked into this Convert GPS coordinates to coordinate plane. The problem is that I don't know if this would work and wanted to confirm beforehand. The image provided in the post was for indoor location, and it was from 11 years ago.
I used Location and Google Maps packages for flutter. The player's latitude and longitude correspond to the actual latitude and longitude that the simulator in the android studio shows when tested.
The layout in question and a close comparison to the result I am looking for.
Any help on this matter would be appreciated highly, and thanks in advance for all the help.
Edit:
After looking more at the matter I tried the answer of this post GPS Conversion - pixel coords to GPS coords, but it wasn't working as intended. I took some points on the image and the correspond coordinates, and followed the same logic that the answer used, but reversed it to give me the actual image X, Ypositions.
The formula that was given in the post above:
...ANSWER
Answered 2022-Jan-12 at 08:20First of All, Yes you can do this with high accuracy if the GPS coordinates are accurate.
Second, the main problem is rotation if the field are straight with lat lng lines this would be easy and straightforward (no bun intended).
The easy way is to convert coordinate to rotated image similar to the real field then rotated every X,Y point to the new straight image. (see the image below)
Here is how to rotate x,y knowing the angel:
QUESTION
I was wondering if anyone knows a way to combine a table and ggplot legend so that the legend appears as a column in the table as shown in the image. Sorry if this has been asked before but I haven't been able to find a way to do this.
Edit: attached is code to produce the output below (minus the legend/table combination, which I am trying to produce, as I stitched that together in Powerpoint)
...ANSWER
Answered 2021-Dec-31 at 13:24This is an interesting problem. The short answer: Yes, it's possible. But I don't see a way around hard coding the position of table and legend, which is ugly.
The suggestion below requires hard coding in three places. I am using {ggpubr} for the table, and {cowplot} for the stitching.
Another problem arises from the legend key spacing for vertical legends. This is still a rather unresolved issue for other keys than polygons, to my knowledge. The associated GitHub issue is closed The legend spacing is not a problem any more. Ask teunbrand, and he knows the answer.

QUESTION
I borrowed the R code from the link and produced the following graph:
Using the same idea, I tried with my data as follows:
...ANSWER
Answered 2021-Dec-27 at 22:55You can do calculations within a function for the x and y values to construct the ggplot which extends the circle all the way round and gives labels correct heights.
I've adapted a function to work with other datasets. This takes a dataset in a tidy format, with:
- a 'year' column
- one row per 'event'
- a grouping variable (such as country)
I've used Nobel laurate data from here as an example dataset to show the function in practice. Data setup:
QUESTION
I have built a pixel classifier for images, and for each pixel in the image, I want to define to which pre-defined color cluster it belongs. It works, but at some 5 minutes per image, I think I am doing something unpythonic that can for sure be optimized.
How can we map the function directly over the list of lists?
...ANSWER
Answered 2021-Jul-23 at 07:41Just quick speedups:
- You can omit
math.sqrt() - Create dictionary of colors instead of a list (that way you don't have to search for the index each iteration)
- use
min()instead ofsorted()
