I have a vector in a map that I can modify your color in real time with layer.redraw() and a color selector. But when I change the color of this vector and activate modifyFeature, it loses the vertices, and Openlayers just shows me the virtual vertices to drag.
Someone have this problem before?

I'am using reactJS and want to design a component with following functionality :
Display pixelated image which is able to zoom in and zoom out at pixel level.
When clicked on image , display a marker- which can be a dot or icon at specific position.
When image is zoomIn/zoomOut, marker size and position should not change.
Even after zoomIn/zoomOut when clicked on image, marker should get repositioned at proper pixel on the image.
I am thinking of applying same logic as used in the maps/ leaflet. Like they maintain separate layers for map and markers on the map. If we zoomIn/out maps it won't affect the marker position or size, same functionality I want for the image.
Anyone with the solution or related library will be welcomed !
(For reference, I want this design for marking GCP(Ground Control Points) on the image, which requires very precise marking at pixel level)
I want my extension to be able to get the positions of all CSS color decorators.
This is my extension "Blockman":
https://marketplace.visualstudio.com/items?itemName=leodevbro.blockman
It highlights nested code blocks, but one big problem is the CSS color decorators, they make text wider by 2 char-space on each decorator, so the edges get rendered inside, because render is calculated by char count.
If I have the positions of all the decorators, then I'll be able to correctly compute the edges of the blocks.
I am implementing a scenario where I am trying to animate map accuracy indicator surrounding the position indicator using here maps
It should animate like ripples along the route with position indicator
But could not find any interface in HereMaps Android SDK document
Can you help with the same ? !
Ripple animated circle
What about using different MapCircles on the coordinates of the current position in different colors?
A MapCircle represents a type of MapObject in the shape of a circle with an assigned radius distance and a GeoCoordinate center. It can be created by calling the constructor MapCircle(double radius, GeoCoordinate center).
I want draw shape that is change in timeline with make some keyframe with "path"
for Ex: the first keyframe include 3 vertex and next keyframe have 4 vertex.
when i add extra keyframe in time line for new keyframe the shape in last keyframe will change! why? or when i delete vertex the shape in last keyframe will change
You cannot add or remove vertex from a shape in the timeline. You can only animate them.
Pick a place you can hide the vertex and key frame it from there.
For example. If you wanted a triangle to become a square. you'd make a triangle but with 4 vertex points. You could hide the 4th vertex inline on one side, and then keyframe the top points to make a square. After effects doesn't "generate" new shapes in the way you're thinking.
See the 4 points?
Triangle with 4 vertex
This should then be animated in your timeline to your desired position and thus, the shape you want.

When I create an a-plane and assign an attribute color="red", the color is applied to one side only. I added rotation animation to the plane and the back of the plane is white: fiddle.
What would be the method to get a plane colored from both sides? Should I create 2 planes of same color and then rotate one so that they are back to back and to the user looks like a single plane?
There is a material property called side. If you set it to double, the material will be applied both to front and back
<a-entity material="side: double"></a-entity>
