Replacing vector images in a PDF with raster images
I had a similar issue, and solved it using ImageMagics convert tool (http://www.imagemagick.org/script/index.php). That comes with linux and runs fine on Windows/Cygwin or OS X convert -density 300 largeVectorFileFromR.pdf out.pdf With -density 300 you control resolution (as DPI). Downside: Text is rasterized as well, I understand that Michael does not want this.
Direction of two points
Answer 1: it is Vector(x2-x1,y2-y1) Answer 2: Normalizing means to scale the vector so that its length is 1. It is a useful operation in many computations, for example, normal vectors should be specified normalized for lighting calculations in computer graphics. The normalized vector of v(x,y) is vn(x/Length(v), y/length(v)). HTH
Xcode: Vector images from PDF bad quality
I would set the Preserve Vector Data flag on the asset here: This will make it render as a pdf and scale properly.
VectorDrawable with GoogleMap BitmapDescriptor
Possible workaround: private BitmapDescriptor getBitmapDescriptor(int id) { Drawable vectorDrawable = context.getDrawable(id); int h = ((int) Utils.convertDpToPixel(42, context)); int w = ((int) Utils.convertDpToPixel(25, context)); vectorDrawable.setBounds(0, 0, w, h); Bitmap bm = Bitmap.createBitmap(w, h, Bitmap.Config.ARGB_8888); Canvas canvas = new Canvas(bm); vectorDrawable.draw(canvas); return BitmapDescriptorFactory.fromBitmap(bm); }
Are there any Android Drawable designers?
I faced the same problem and I’ve just released a little library on github that allow to export svg to drawable more quickly. https://github.com/r3gis3r/svg2drawable Hope can be useful for you.

The canvas (tkinter) object has the postscript function; you can use … Read more
What is the difference between cubic bezier and quadratic bezier and their use cases?
As you’ve discovered, both Quadratic curves and Cubic Bezier curves just connect 2 points with a curve. Since the Cubic curve has more control points, it is more flexible in the path it takes between those 2 points. For example, let’s say you want to draw this letter “R”: Start drawing with the “non-curvey” parts … Read more
Error when trying to overload an operator “/”
In Python 3.x, you need to overload the __floordiv__ and __truediv__ operators, not the __div__ operator. The former corresponds to the // operation (returns an integer) and the latter to / (returns a float).
