fastgrab's Introduction

FastGrab

Fastgrab is an opensouce high frame rate screen capture package. A typical capture frame rate at a resolution of 1080p on a modern machine is ~60 fps. There are several other such packages in the wild that are opensource as well, but none of them is as fast or provides a simple way of obtaining the captures image as a numpy array out of the box. The default behavior of fastgrab is to provide the user with the image as a numpy array. Beyond that the user is free to manipulate the image since the pixel data is accessible via a fast and flexible array, i.e a numpy array.

Typical capture frame rate on a modern machine

resolution	fps
360p	> 800
720p	260
1080p	200
4K	20

Usage example

  from fastgrab import screenshot
  # take a full screen screenshot
  img = screenshot.Screenshot().capture()
  # >> img is a numpy ndarray, do whatever you want with it
  # (optional)
  # e.g it can be displayed with matplotlib (install matplotlib first)
  from matplotlib import pyplot as plt
  plt.imshow(img[:, :, 0:3], interpolation='none', cmap='Greys_r')
  plt.show()

Getting Started

Fastgrab was initially developed in 2016 as part of an aimbot (for quake live). Fastgrab is developed and tested on linux. As far as the pre-requisited listed below are satisfied, it should work as expected on windows and osx. The low-level API of Fastgrab is implemented using the cpython, Numpy and X11 C APIs.

Comparison with other packages

The following comparison has been done a Intel i7-6700HQ with 16 GB ram at a 1080p resolution. fastgrab is designed to be fast and does not provide any features beyond capturing the screen, unlike the other packages mentioned in the comparison below that do many great things.

package	fps
fastgrab	200
python-mss	180
autopy	34
pyautogui	8
pyscreenshot	4

to benchmark fastgrab run the script examples/benchmark.py

Prerequisites

python >= 3.6 (python 2 is not supported)
Numpy >= 1.15
gcc >= 4.8.5
X11 => 1.20

note that fastgrab could work with lower versions but I have not tested it (and probaby will not).

Installing

Fastgrab can be installed in several ways:

pip install fastgrab

pip install git+git://github.com/mherkazandjian/fastgrab.git

git clone https://github.com/mherkazandjian/fastgrab.git
cd fastgrab
python setup.py install

Running the tests

Execute the following in the source root dir

pytest tests

pip install tox-pipenv
pipenv install
tox

setup.py imports numpy

Hello,

numpy, which is not in the standard library, is currently imported in setup.py.

This breaks pip behavior when installing fastgrab (e.g., when numpy is not installed).

This hack would probably solve this.

ModuleNotFoundError: No module named 'fastgrab._linux_x11

Module not found.

fastgrab has not been updated for over 2 years,
please do something about it.

ImportError: cannot import name 'screenshot' from 'fastgrab'

Please fix.

Yo!
what way do u think is more optimized?
Each Thread print with specific area (bbox) and do your own stuffs
or
1 thread print and the others crop ur needed area to find your stuffs??

i`ve many thread and each one find something in a specific area in RPGMMO
(Buff / Debuff), Life, Mana, Speed, hunger, status, etc.

numpy array not compatible with opencv

please add support for using with opencv as this is basically what im looking for for my bot project but the array is not compatible with opencv and would defeat the purpose to reconvert it back. would be helpful if there was a function that just had it already converted for opencv

Failing to install on Ubuntu 20.04 with pip3 and via setup.py

I have all pre-requisites installed and gcc fails to build. I have attached the setup.py install output.
