rasterize

I am trying to export a fairly simple html to canvas and then png. To do so, I am using rasterizeHTML ( http://cburgmer.github.io/rasterizeHTML.js/ ). The problem that I am facing is that I get a warning like if I was loading an external image/resource, but I am not. This is what I have tried: HTML: <canvas height="500" width="500" id="rasterizer"></canvas> Javascript var canvas=document.getElementById("rasterizer"); rasterizeHTML.drawHTML('<div width="300px" height="300px" > <div style="width: 200px;height: 200px;position: absolute;top: 50%;left: 50%;margin: -100px 0 0 -100px;"><div style=

I'm using PhantomJS 64 bit in my PHP application to dynamically capture an HTML page to be emailed to the user. phantomjs rasterize.js "http://..." /path_to_images/image.png This method works fine when I run the above on the command line but when the PHP script runs the command using exec it fails with no output and returns exit code 11. If I switch it to use the 32 bit phantomJS binary, the command succeeds but fails to load the google JSAPI on the page since with error Reference Error: can't find variable google . This is a problem because not all of the page content is loaded and captured

Is it possible to set the data type (Byte, Float32) when using gdal.Rasterize in gdal 2.1? Currently, I use gdal.Translate to convert to Byte, but this is inefficient. tif = my/target.tif shp = my/source.shp tiftemp = my/temp/solution.tif rasterizeOptions = gdal.RasterizeOptions(xRes=20, yRes=20, allTouched=True etc.) gdal.Rasterize(tiftemp, shp, options=rasterizeOptions) #translate to Byte data type (not supported by Rasterize?) gdal.Translate(tif, tiftemp, outputType=gdal.GDT_Byte, creationOptions=['COMPRESS=PACKBITS') I am aware that it is possible to use subprocess.check_call('gdal

I'm trying to rasterize and fill a hypersphere. In essence, I have a d-dimensional grid of fixed size and a sphere (center, radius) and want to find out which cells of the grid overlap with the sphere and store their coordinates. I am aware of the Midpoint circle algorithm which takes advantage of 8-way mirroring and produces the outer cells (border) of a circle. I have also altered the linked wikipedia code so as to fill the circle (that is, to produce the coordinates of all cells inside the border). However I am unaware of any algorithms for higher dimension. For example in 4d, I've been
