– how much your want the image to ‘spread’ or blur, in pixels – can be either ‘0’ or at a minimum double that of the sigma value – how big an area the operator should look at when spreading pixels Rotate image 45 degree anti-clockwise/counter-clockwiseĬonvert input.png -rotate "-45" output.png Suppose, if your input image is 800×600 pixels then the resized output image will be 400×300 pixels in size.Ĭonvert input.png -rotate "90" output.png The following command will resize the image into half of its size. Resize image to percentage size by maintaining the aspect ratio

So, this is kind of Image Enlarging feature onlyĬonvert input.png -resize 100x100\< output.png.

Only resize image that is smaller than the resize size

So, this is kind of Image Shrinking featureĬonvert input.png -resize 100x100\> output.png.

if we provide 50×50 pix image then it will not resize and remain as it is.

if we provide 200×200 pixel size image, then it will be resized to 100×100 px.

Only resize image that is larger than the resize size

the image will be resized exactly into 100×100 pixelsĬonvert input.png -resize 100x100\! output.png.

Resize image to 100×100 pixels ignoring aspect ration Suppose, if your input image is 800×600 pixels then the resized output image will be 100×75 pixels in size.Ĭonvert input.png -resize 100x100 output.png Resize image to 100×100 pixels by maintaining the aspect ratio Here, we convert the image from PNG to JPEG format:Ĭonvert shadow.jpeg -resize 50% shadow1.png Png:text: 2 tEXt/zTXt/iTXt chunks were found Png:IHDR.interlace_method: 0 (Not interlaced) Png:cHRM: chunk was found (see Chromaticity, above) Png:bKGD: chunk was found (see Background color, above) Get the detailed information of the same image: Version: ImageMagick 7.0.7-23 Q16 x86_64 Ĭopyright: © 1999-2018 ImageMagick Studio LLCĭelegates (built-in): bzlib freetype jng jpeg ltdl lzma png tiff xml zlib The identify program can also be used to get the installed version number of ImageMagick itself by running the following command: – get more detailed information using the -verbose option – get the number of seconds that ImageMagick took to read and process the image

– get the format of the image (JPEG, PNG, etc.) – check if the image is colormapped or not – report if an image is incomplete or corrupt – describe the format and characteristics of one or more image files We can use ImageMagick’s identify program to get the detailed information about any image.
