imt.savefig.py only saving images at 72 dpi #137

Closed elliottwarren closed 2 years ago

elliottwarren commented 2 years ago

imt.image_file_postproc() in imt.savefig() is changing or resaving the dpi of figures to 72, when the original dpi could be much higher (e.g. 300).

Code snippet to recreate the issue:

import ImageMetaTag as imt

pathname = '/home/h01/ewarren/cylc-run/u-al685_TCbogus_highres/share/data/Plots/tcver/u-ck824_v_u-co412/FS_Central_Pressure_Bias.png'

img_tags = {'aggperiod': 'None', 'datatimes': 'QG', 'dates': 'None', 'fcrs': 'None', 'period': 'None', 'difference': 'None', 'grid': 'None', 'scales': 'None', 'stations': 'None', 'levels': 'None', 'params': 'None', 'truth': 'None', 'fields': 'Central Pressure', 'probbins': 'None', 'areas': 'Global', 'expid': 'u-ck824 Vs u-co412', 'plot type': 'Forecast', 'stats': 'Bias', 'thresh': 'None', 'tiletype': 'None', 'storm name': 'None'}

imt.image_file_postproc(pathname, img_tags=img_tags)

Example image (with a dpi of 100 before being passed through imt.image_file_postproc()): FS_Central_Pressure_Bias
