`./configure` scripts often look for *-config scripts to determine if software packagesare installed, and what additional flags to use when compiling and linking.
Some "config" scripts were found in your path, but not in system or Homebrew folders.

The identify command recognizes these options. You can find additional examples of using identify in Examples of ImageMagick Usage. Here is a special define that outputs the location of the minimum or maximum pixel of the image: identify -precision 5 -define identify:locate=maximum -define identify:limit=3 image.png Here we display the image texture features, moments, perceptual hash, and the number of unique colors in the image: -> identify -verbose -features 1 -moments -unique image.png The depth and dimensions of a raw image must be specified on the command line: -> identify -depth 8 -size 640x480 image.raw To get the print size in inches of an image at 72 DPI, use: -> identify -format "% by % inches" document.png Note, the image signature is generated from the pixel components, not the ima Next, we look at the same image in greater detail: -> identify -verbose rose.jpgįormat: JPEG (Joint Photographic Experts Group JFIF format) Rose.jpg JPEG 70x46 70x46+0+0 8-bit sRGB 2.36KB 0.000u 0:00.000īy default, identify provides the following output:įilename image-format widthxheight page-widthxpage-height+x-offset+y-offset colorspace user-time elapsed-time
To get started, lets identify an image in the JPEG format: -> identify rose.jpg We list a few examples of the identify command here to illustrate its usefulness and ease of use.
#INSTALL IMAGEMAGIC MAC HOW TO#
See Command Line Processing for advice on how to structure your identify command or see below for example usages of the command. Many more attributes are available with the verbose option. The information returned includes the image number, the file name, the width and height of the image, whether the image is colormapped or not, the number of colors in the image, the number of bytes in the image, the format of the image (JPEG, PNM, etc.), and finally the number of seconds it took to read and process the image. It also reports if an image is incomplete or corrupt. The identify program describes the format and characteristics of one or more image files.
