Viewer for Python IMage Sequence (PIMS).
A graphical user interface (GUI) for PIMS (screenshot below)
This viewer is based on PyQt5 and is able to work with N-dimensional image files that are opened by PIMS.
Also, it has a plugin infrastructure that can be used to extend the main functionality.
Pimsviewer can be installed using conda:
conda install -c conda-forge pimsviewer
Alternatively, it can also be installed using pip:
pip install pimsviewer
When installing the latest source version, always install it with
pip (and not with
python setup.py develop, this will lead to dependency errors for
pip install .
pip install . -e
Starting the viewer
After installing the viewer, an executable
pimsviewer is available. Simply run the command via your terminal/command line interface.
$ pimsviewer --help Usage: pimsviewer [OPTIONS] [FILEPATH] Options: --example-plugins / --no-example-plugins Load additional example plugins --help Show this message and exit.
All examples below are also available as script files in the
pimsviewer --example-plugins, you can preview the example plugins used below.
Example 00: Using the viewer from Python
You can use the viewer in a Python script as follows:
import sys from pimsviewer import GUI from PyQt5.QtWidgets import QApplication filepath = 'path/to/file' # Class names of extra plugins to add plugins =  app = QApplication(sys.argv) gui = GUI(extra_plugins=plugins) gui.open(fileName=filepath) gui.show() sys.exit(app.exec_())
Example 01: Using the viewer from Python (the shorter way)
Or, if you do not need a reference to the actual object but you just want to start the program:
from pimsviewer import run run('path/to/file')
In both cases, you can omit the file path.
Example 02: evaluating the effect of a processing function
This example adds a processing function that adds an adjustable amount of noise to an image. The amount of noise is tunable with a slider.
from pimsviewer import run from pimsviewer.plugins import ProcessingPlugin run('path/to/file', [ProcessingPlugin])
Example 03: annotating features on a video
This example annotates features that were obtained via trackpy onto a video. Tracked positions are loaded from a pandas DataFrame CSV file by the user.
from pimsviewer import run from pimsviewer.plugins import AnnotatePlugin run('path/to/file', [AnnotatePlugin])
Your own plugin?
By looking at the code for the example plugins, it should be fairly easy to extend pimsviewer using your own plugins. Contact one of the maintainers if you have any trouble writing your own plugins.
Download the file for your platform. If you're not sure which to choose, learn more about installing packages.
