wxfalsecolor

A wxPython GUI for the Radiance falsecolor2 tool

Download

Latest binary packages can be found in the Releases section.

Usage

On Windows simply drag-and-drop a Radiance *.hdr file on the executable.

To start from the command line:

python wxfalsecolor.py [image.hdr]

falsecolor2 is a Python rewrite of the falsecolor c-shell script in the Radiance distribution. The main purpose was to have a falsecolor script for Windows but I added a few extra bits on the way.

wxfalsecolor is a graphical frontend to falsecolor2. It also implements a few features of ximage so it can be used to display Radiance RGBE images and read luminance/illuminance values.

Like the original, falsecolor2 relies on the Radiance image tools which you need to have installed on your system.

Features

falsecolor2 supports all features of the original falsecolor. I have added a few new features and some of the original features behave a bit differently:

• The formatting of the default legend is different.
• -cb creates a falsecolor image of discreet colours instead of an obese variation of contour lines.
• -h shows a summary of the command line options. This option does not create an image but prints a help message to stdout (terminal).
• -lp allows you to specify the legend position; legends above and below the image are horizontal instead of vertical.
• -mask <minvalue> masks all values below minvalue with the background color (black).
• -z creates legends starting at 0
• -s auto option for automatic legend scale adjustment

With wxfalsecolor you can

• load and display Radiance RGBE images
• drag-and-drop images in a desktop environment
• view image headers
• display RGB and Lux values (even after conversion to falsecolor image)
• set falsecolor2 options interactively
• set pcond options interactively
• display labels for spot and average pixel values (like ximage)
• save image as bitmap

Documentation

To open a file simply drag a Radiance HDR image on the executeable (Windows) or start the application from the command line (OS X and Linux):

python wxfalsecolor.py [image.hdr]

Detailed usage information is on the wxfalsecolor - Usage page.

History

The code base was migrated from the original 'pyrat' repository on code.google.com and copied into this repository dedicated to wxfalsecolor.
