Resize image to exact size by maintaining aspect ratio nodejs












0














I want to resize image to an exact size by maintaining aspect ratio and filling the empty space with transparency using nodejs.



I am able to do it using canvas. But due to some server os issues I can not use canvas.



I tried with imageMagick and gm. But couldn't find any option like these. Please show me a way to do this.



Thanks in advance.

          In ImageMagick, you can resize and fill to the exact size by



          convert image -resize WxH -background none -gravity center -extent WxH output


          Input:



          enter image description here



          Here I will make the background black so you can see that if fills it out.



          convert lena.jpg -resize 400x300 -background black -gravity center -extent 400x300 lena1.jpg





          enter image description here

            In case you have been successful using the canvas for resizing images, you can check out https://github.com/Automattic/node-canvas this repo.



            As already mentioned you also resize images using ImageMagick by processes in NodeJS ( http://www.imagemagick.org/Usage/resize/ )



            convert dragon.gif  -resize 64x64  resize_dragon.gif


            In case you have a lot of images, I would suggest that you write a terminal script ( NodeJS can achieve that as well ).



            I hope it helps, in case you have more queries, feel free to ask.
