Make thumbnail images of posters from PDF files

<2015.6.26>

On the Linux/Cygwin/OS X command line:

$ convert -thumbnail 300 Cate_Brown_Roldan_SfN_2014_FINAL.pdf outputFileName.png

To create thumbnail image of one page of a multi-page PDF file (like a journal article):

$ convert -thumbnail pdfFileName.pdf[0] outputFileName.png

[0] is for first page, [1] for second, etc.

Crop images using command line

<2016-01-08>

Anthony did this to crop an SPM rWLS residual time seriers figure (blank except for the very bottom) using command line tool ImageMagick (“convert”).

convert rwls_residual_time_series.png -gravity South ...
   -crop 0x30%+0+0 rwls_residual_time_series_crop.png

This means: “Crop from bottom up (-gravity South) leaving all width and removing 30% of height (0x30%+0+0)”

Got advice from this and related pages:
