How to attach a logo to a leaflet map?

Asked 2021-May-10 at 11:07

I have a leaflet map with some interactivity on it, and i just want to add a fixed logo on the top left corner of the map.

Here is my code: https://codepen.io/paul-k/pen/OJWYaxw

I have tried to use coordinates, but the fact is that the logo disappear when you switch to another part of the map.

I don't know how to pin a logo which doesn't move on the top left corner of the map!

Thanks for helping :)

Setting transparent background to this WebGL with OGL Flowmap effect?

Asked 2019-Nov-18 at 16:30

I am trying to create the Flowmap effect from OGL examples but with partially transparent PNG image. I was struggling with this issue for many hours now and I don't even know whether it is the texture's fault the flowmap effect or any other thing. How can I set the background transparent instead of black?

There are two changes you need to make.

In your Program declaration, you need to add transparent: true
In your Fragment shader, change the output to gl_FragColor = texture2D(texture, uv);

The first change changes the blending type to use alpha - by default in WebGL blending is disabled.

The second uses the alpha channel of the texture. In the original example, only the rgb (red, green, blue) channels are used.

You can use the fact that the CanvasFlowmapLayer extends L.GeoJSON

You just need to overload the method creating the marker and add your popup there ...

QUESTION

Leaflet Canvas Libraries

Asked 2019-Feb-22 at 08:59

There are a number of libraries that provide drawing on a canvas such as:

Leaflet.Canvas-Markers

leaflet-canvas-layer

Leaflet.Canvas-Flowmap-Layer

gLayers.Leaflet

react-leaflet-canvas-layer

However, I know leaflet canvas rendering has come along way and wondering if these libraries are somewhat redundant now.

Does Leaflet internal canvas rendered basically has the same functionally of these other library's?

Or in other words can everything done in these other library's be done within leaflet canvas renderer?

No.

Leaflet's L.Canvas provides support for rendering lines, polygons and circles. The plugins you listed provide support for drawing other stuff (e.g. bezier curves, arcs, per-tile canvases).

QUESTION

Leaflet Curve (Bézier) using Angular-leaflet-directive

Asked 2018-Oct-11 at 11:59

I'm using angular-leaflet-directive in my AngularJS application to show Leaflet maps. At this time I'm playing around with paths - drawing lines between two points. This is working great, but at this time it is rendered as a straight line. I want a smooth Bézier curved line. I've found 2 plug-ins on the Leaflet site Leaflet.Curve and Leaflet.Canvas-Flowmap-Layer, but none have an AngularJS implementation.

Question: has anyone integrated this into the angular-leaflet-directive? if so, can you give some pointers how to do this? I've looked at the code, but I don't know how to start. And of course I've Googled around but found nothing.

QUESTION

Matlab Interp2 function behaviour differently compared with OpenCV Remap

Asked 2017-Oct-17 at 04:57

I am trying to look for an equivalent OpenCV function for interp2 and I refer to this poster to use remap function in OpenCV.

cv::remap (in opencv) and interp2 (matlab)

However, I realized that there is a significant difference of the output between these two functions. Here is my Matlab Code

...

ANSWER

Answered 2017-Oct-17 at 04:57

The difference in the results is related to difference in indexing between c++ and MATLAB that is 0-based and 1-based respectively.

interp2(U,X,Y,'linear',NaN) is the same as interp2(1:3,1:3,U,X,Y,'linear',NaN) changing it to interp2(0:2,0:2,U,X,Y,'linear',NaN) you will get the same result as OpenCV.

If you want result of remap to be the same as that of interp2 you can shift the xmesh and ymesh one step back and search for negative locations to produce nan values.
