I'm using Figma API to get a figma document but I can not get the rotation of a node. How is the rotation of an object calculated?
If you are using the Figma plugin API, you can just access rotation property. See the documentation here.
If you are using the Figma REST API, you can get it from the relativeTransform property. Given a transform value of [[m00, m01, m02], [m10, m11, m12]], I believe the rotation should be atan2(-m10, m00). This ends up being the angle of the x axis of the transform. Note that relativeTransform is only present if you pass geometry=paths. See the documentation here for more information.

I'm testing the example https://github.com/petrbroz/forge-potree-demo trying to import a NWD and point cloud into the Forge Viewer but can't make them match the coordinates.
I confirmed on Navisworks that both PC and model are aligned at 0,0,0. But they are displaced more than 200' in the Viewer.
What we did tried
Point cloud was converter using Potree converted 1.6 and 1.7 https://github.com/potree/PotreeConverter/releases/tag/1.7
The point cloud is scaled from meters to feet using let scale = new THREE.Vector3(3.28084,3.28084,3.28084);.
The models are being inserted with a global offset of 0,0,0. globalOffset: {x:0,y:0,z:0}
We created a sphere at a know point directly in Threejs using coordinates in foots and it matches the location on the NWD.
We found that potree converter is not 100% compatible with the sample, a quick fix is needed on the line 464 to read categories created by the converter.
var pointAttributeName = pointAttributes[i].name.toUpperCase().replaceAll(' ','_');
Also we needed to add a new category around line 434
PointAttribute.RGBA = new PointAttribute(PointAttributeNames.COLOR_PACKED, PointAttributeTypes.DATA_TYPE_INT8, 4);
Without those two latest fixes we can't load the point cloud.
What are we missing?
We can override the location by hand but the final coordinates doesn't make sense with the project. Too arbitrary. Could the two fixes be the problem? What should be an alternative?
We found the problem, potree was using a bounding box based on absolute units from the actual point cloud bounding box.
This makes sense if you want the point cloud to be on the center of the scene. But not at our case.
So, if you override this feature by changing potree.js bounding box set from
boundingBox.min.sub(offset);
boundingBox.max.sub(offset);
tightBoundingBox.min.sub(offset);
tightBoundingBox.max.sub(offset);
to
tightBoundingBox.min.sub(offset);
tightBoundingBox.max.sub(offset);
boundingBox.copy(tightBoundingBox);
the point cloud will align with the model.
FYI: The fixes we made where actually making us able to run potree converter 1.7 instead of 1.6 as specified in the demo readme.
Hi looking for Adding gps coordinate to image in angular and uploading and extracting coordinate. Is it possible ? any library open source ?
Following this answer, you may use the node package exiftool. With this package you can add meta data to a picture using tags. You can then read those tags on a picture and check if they are defined. That way the coordinates are directly store onto the picture file itself.
Preferably, I'd like to use an array, iterating over each pixel and setting the R G B values.
And I don't think that I can use HTML canvas in any way. I'm hoping to build it right on top of a Google Doc without additional libraries or references to external websites.
Everything I have found on the Image Class, type is about positioning or resizing, but not helpful for stating the image.
ImageItem .setImage() looks promising, but is not particularly descriptive.
You can implement your own encoding algorithm (or migrate someone else's) and transform your pixels array into an image blob compatible with the ImageItem.setImage() method.
I'd like to visualize a geojson file in the EPSG:4326 coordinate reference system using D3.js version 3. I'm aware it's better to use the newest version, but alas I'm restricted because of old software that doesn't support higher versions.
I wrote this code: https://bl.ocks.org/FrieseWoudloper/141945ce346639013ac1ced8e4c071b7
In the resulting output there is an SVG element with paths, but I don't see it. I think I have the translate and scale arguments wrong, but I don't know how to determine the right values. Could you please give me any directions on how to fix this?
I am really sorry to post this question, because most likely the solution will be really simple. But I am completely out of search string ideas.
I have a running Geoserver and some custom shapefiles describing buildings etc. I can requesting maps as pngs with the WMS interface and display on a website. So for so good.
In the next step I want to enable the user to specify a coordinate an draw a little marker on the map. This position should not be stored anywhere, I just want to draw it for this user. I am pretty sure this is possible with a WMS request and an inline feature, but I had not any luck finding a working solution and I am out of google search strings.
Please help me before I start drawing overlays over a png map.
You can do this with an inline feature in your SLD - See http://lyceum.massgis.state.ma.us/wiki/doku.php?id=wms:sld:inline_feature for an example.
You can let OpenLayers do the drawing on the client.
Check this example to see how it can be done. It demonstrates how to draw lines, points, and polygons:
