mtimg

Create beachball images from a focal mechanism or a moment tensor.

Description

mtimg generates custom images from moment-tensor solutions and focal mechanisms in different image formats. If unspecified, the file format is determined by the ending of the output file. mtimg is called, e.g., by the default script for report generation @DATADIR@/mtv/tools/mtv-plot-extended-log.py configured in scmtv by mtv.extendedLog.script for report generation.

Example:

  • Generate a PNG image for focal mechanism with strike/dip/rake = 110/30/45 deg

    mtimg 110 30 45 -d 200x200 -o mt.png

  • Write JPEG image with 95% quality for moment tensor with RR/TT/PP/RT/RP/TP = 1/2/3/-1/0/-1 to stdout and then into file.

    mtimg --quality 95 -f jpg 1 2 3 -1 0 -1 > /tmp/mt.jpg
