DETECT IMAGE SIZE

[foruforewer]

I want to detect input image size can anyone guide?

[fmw42]

convert image -format "%wx%h" info:
or
identify -format "%wx%h" image

gives the width x height


convert image -format "%b" info:
or
identify -format "%b" image

gives the filesize


see string formats at http://www.imagemagick.org/script/escape.php

Next que.. after getting height and width, i want to store them in some variable and add 100, so i had tried further as below but not working. can you please guide in this?

Code: Select all

set ht=identify -format "%h" im1.png
set wd=identify -format "%w" im1.png
set /A ht=ht+100
set /A wd=wd+100
set "sz=%ht%x%wd%"
convert -size sz xc:black output.png

but it wont working at
1) storing in ht,wd
2) defining concatenated string by sz

[fmw42]

on unix

newht=$((ht+100))

or you can compute it from scratch

newht=`convert image -format "%[fx:h+100]" info:`
or
newht=$(convert image -format "%[fx:h+100]" info:)

IMv7 "magick" command will allow you to do all this in the one command line (or file script).
