display -size not working

Post by steidley » 2018-06-29T08:27:17-07:00

When I show an image using

Code: Select all

$ display -verbose IMG_0017.JPG
IMG_0017.JPG JPEG 3072x2048 3072x2048+0+0 8-bit sRGB 2.818MB 0.090u 0:00.220
This is far too large of an image for my display, so I tried to modify the options with

Code: Select all

$ display -size 1024x768 IMG_0017.JPG
The image displayed, but it did nothing to the geometry of the image. It was just as large as before.

So I ran the command again, this time using the debug option

Code: Select all

$ display -debug -size 1024x768 IMG_0017.JPG
display: unrecognized event type `-size' @ error/display.c/DisplayImageCommand/901.
Other statistics:

Code: Select all

$ which display
/usr/bin/display

$ display -version

I know the current version of ImageMagick is at release 7 now, but still... it seems like this should work. Any thoughts?

Thanks!

-size will not help. It specifies the size of a new image. You want to resize it. Try

Code: Select all

magick display -resize 1024x1024 IMG_0017.JPG

Ah! Perfect.

That is an interesting command. I like how it gives you a "best fit". For instance, I chose a picture that had a portrait orientation, set the resize to 1024x1024, and it made it as large as possible, while honoring as much of the input as it could.
