kandi X-RAY | CanvasMap Summary

CanvasMap is a JavaScript library typically used in User Interface, Canvas applications. CanvasMap has no bugs, it has no vulnerabilities and it has low support. You can download it from GitHub.

To extend CanvasMap with an additional projection, duplicate an existing projection file in the projections folder and change the function name and the included toString() and forward() functions. The forward function receives longitude and latitude values in radians. The projected coordinates have to be written to the xy array. The xy parameter is only for returning the projected coordinates and does not contain valid data when the function is called. Important: use Apache Ant to concatenate and minify all JavaScript files in the src folder. The default Ant target creates CanvasMap.js and CanvasMap-min.js. To run Ant, cd to CanvasMap, then type ant. To apply the new projection to the map, change UI.js. If you use the "ProjectionList" map, add your projection to the getProjection function in UI.js. Also include your projection in the element in index.html. The value for the new in the element has to be unique and match the projectionName parameter of getProjection in UI.js.

How to filter layers using forEachFeatureAtPixel method

Asked 2020-Apr-14 at 14:38

I'm having hard time figuring out how to filter layers using forEachFeatureAtPixel method. I was going trough documentation but without any success so far. I basically want to filter layers and apply overlay style on event (for example "click") or to be more precise I want to implement hover effect using this example but with isolated layer.

In example above is used like this to get feature:

Ok, I finally did it. I was a bit hasty while reading documentation, problem was in callback function. I needed to return feature as it is pointed out in documentation. ...To stop detection, callback functions can return a truthy value.

So, proper formatting is like this: (I'm using 4.5.6 version)

Inside your open function, rather than setting the center and zoom properties of the map, call the geocoder, and use the result to set the map center.

QUESTION

Why is a blank image in Tkinter 1/4 the size I specify?

Asked 2018-Jul-13 at 03:34

I'm creating a canvas in a Python program using Tkinter and putting a solid single color image in it. (I need an image in there because later I'll be replacing that image with another, which is why I don't just specify the background.)

I specify the size of the canvas and have checked it when the window is open. It's 640x640. I specify the blank gray image to be the same size, but it comes up as 320x320, filling only a quarter of the canvas.

I know I can just change the image size to 1280x1280 so the whole canvas will be gray, but when I add other images to the canvas, I don't want to run into similar problems.

Here's the program:

The entire image is displayed, but centered at canvas origin (0, 0), this is why you can only see the bottom right 1/4 of it.

You need either to off set the display to the center of the canvas (WIDTH // 2, HEIGHT // 2), or set the image handle to the top left corner.

Here is one approach:

Higher Order Component: Default Props

I have this code and trying to wrap a HOC with a react Class. What I want in the first place is to overwrite one part of the default params. So here is my code (you don't need to read the whole code, the question its just about the defaultProps in the HOC)

First the Component:

ANSWER

Answered 2018-May-28 at 20:01

React merge Props when a component is being created.

Mean, when a component(JSX) is being instantiated it creates a public data and private data to it i.e, state and props respectively.

When creating props to a component it takes all the argument props (from callee) and also considers if any default props are declared in that class which it can fill in.

Something like Object.assign({}, { ...defaultProps }, { ...userProps }) where defaultProps will be overrided with userProps. If userProps are not availble then defaultProps would be considered.

So, in your case you need to delete a default prop, this should work.

QUESTION

IE overlapping flexbox when media sizing the page

Asked 2017-Aug-18 at 20:02

I am using the flexbox for displaying a variety of items where the layout will change based on the screen size in order to function on devices. In Chrome, everything displays as expected, however IE is overlapping when going from the largest size to medium size screen. I've managed to replicate this in jsfiddle.

ANSWER

Answered 2017-Aug-18 at 20:02

After extensive trial and error, I've finally resolved the issue so that IE behaves as desired and as seen in Chrome. The CSS needed minor tweaking along with an additional child flex container (flex-1) added and renaming flex to flex-2.

The conflict occurred because of fixed widths being set for #canvasmap and #suppliermetrics. IE was not able to accurately determine sizing for the flex containers. When the sizing is defined specifically to the flex containers (flex-1 & flex-2), IE seems to work as desired.

Summary of changes:

There are three main flex blocks: flex-1, flex-2, and flex-3. An additional container exists (flex-12) that wraps around flex-1 and flex-2. The outer flex container is flex-123. The flex block (flex-12) was updated so that each child item was defined with its own flex container.

Flex container (flex-1) was added.
Flex container 'flex' was renamed to 'flex-2'.
Three main flex blocks (flex-1, flex-2, flex-2_ were defined with flex-direction: row
CSS: #canvasmap width changed from 288pt to 'inherit.' In doing so, the min-width for flex-1 was set for the middle screen size and 'unset' for the smallest screen size.
The flex container flex-12 width was set to 'auto' on the largest screen size
The flex container flex-3 width was set to 100% on the largest screen size
The middle flex block (flex-2) has min-width of 168pt for the largest screen size and is 'unset' for the middle size screen
