dials.export_bitmaps

Introduction

Export raw diffraction image files as bitmap images, optionally exporting images from intermediate spot-finding steps (local mean and variance maps, or sigma_b, sigma_s or threshold-filtered images). Appearance of the images can be altered via the brightness and colour_scheme parameters, and optionally binning of pixels can be used to reduce image sizes.

Examples:

dials.export_bitmaps image.cbf

dials.export_bitmaps models.expt

dials.export_bitmaps image.cbf display=variance colour_scheme=inverse_greyscale
