To manually create thumbnails for the IR

1) ImageMagick commands

magick convert \
wrc08969.pdf[0] \ # use [X] to specify the page number, first page in this case is 0
-resize x160 \ # resize to a height of 160 keeping the width ratio the same. ImageHeight at 160 matches the height of the original (blank) thumbnail generated in DSpace

-flatten \ # flatten the image just in case, so any transparent areas aren't blacked out

-alpha remove \ remove black background

wrc08969.pdf-test.jpg \ # the name of the output image

Example Command

• Save PDF in same folder where you run the command

Note!: Windows 10 upgrade requires "magick convert" instead of just "convert" (source)

2) Next step upload thumbnail to DSpace Item, use the thumbnail bundle:
