you know how in movies some important person can just walk into a room wave
their hand say and hands and they get
like this super detailed closeup of the drug kingpin's nose hair or whatever
well for most of us the experience of trying to enlarge a photo more often
results in a blur that looks like a smear of melted rainbow ice cream now
we've tried to solve this problem in recent years with digital cameras that
capture images with ever higher pixel counts as well as more powerful
computers that can process these images more easily but what if that's not good
enough and you want something that will still look good when it's blown up to
the size of Kim Kardashian's Caboose well this is where vector graphics can
be extremely helpful since they can be rescaled to be as big or as small as
you'd like without any loss of quality but how is that even possible well you
see the reason that traditional raster
images tend to blur and distort when you resize them is because the image file
itself it's like a JPEG or a PNG is
really just a collection of instructions
that tell the computer how many pixels there are what color they should be and
where they go so if you take a lower resolution JPEG and try to stretch it
out Beyond how many pixels are actually defined in the file the computer has to
just guess at what the other pixels in the enlarged image would be a very
imperfect science that might be okay for something like blowing up a 4x6 to a 5x7
for the wall but can result in horrible
looking enlargements and the bigger you go the worse it gets vector graphics on
the other hand work in a fundamentally different way instead of telling a
computer what pixel goes where Vector
files Define images using lines and
shapes and their positions relative to
each other for example the file might
tell the computer I want a line here a
triangle here and a curve that bends exactly like this in some other place
the computer can then render these instructions into a nice looking smooth
lined image each time you enlarge or Shrink it a little like a graphics card
can render a frame of a video game in any resolution you choose providing your
video card can handle it from a set of instructions specifying where things
like polygons should go and because
these instructions remain exactly the same no matter how large or small the
image ends up being Vector files have the significant advantage of taking up
the same amount of space on your computer's drive so you can end up with
an image large enough to look crisp on a highway billboard while still taking up
less than a megabyte well G Linus that sounds fantastic with better quality and
smaller file sizes why aren't all images
Vector great question because vector
graphics are defined by lines and polygons they don't have as much
granularity as raster images which Define Graphics pixel by pixel meaning
that vector graphics at least currently aren't usually a great choice for photos
and other images that are designed to look photorealistic and while there are
tools that can vectorize traditional raster images they tend to lose detail
during this process because the computer has to guess at how to convert the
patterns of pixels into lines and shapes and it's very easy to see the problems
with this if you've ever tried to convert something like a photo of a
person to vector and because modern
screens are raster displays since they're just large arrays of individual
pixels Vector images need to be rastered
ized before they can be displayed properly anyway with lots of modern
software only having partial support for rasterizing vector graphics think about
how you can't resize svgs in Google Chrome for example so they're a good
option for graphic designers and visual artists trying to design cool looking
logos or some such but if you were hoping to upscale all your porn to 8K
using vectors then you've got another thing coming shout out to Pearl Auto for
supporting our Channel pearl auto makes a set of rear view cameras that fit
around your license plate and sync with your smartphone they're quick and easy
to install you only need a screwdriver to mount a camera frame on your license
plate then you just plug in the adapter to your onboard diagnostic port and
mount your phone to your dash you can actually operate it with an app that's
already available for iOS and Android the camera frame has two HD cameras
which give audio and visual alerts to warn you of obstacles in your way
allowing you to switch between normal and wide-angle lenses and even see
around corners in day or night it works on any car has a solar powered panel so
it stays charged on its own it uses Bluetooth technology to connect to your
camera without wires and the Pearl app will automatically update to add
additional features soon rear view cameras will be mandatory on all new
cars in the US not because it's like a fancy pants feature but because it
legitimately improves the safety of the vehicle's operation and pearl auto has a
special offer just for our viewers head over to peo.com tequ to get free 2-day
