Learn to use scripts for image management.
- [Instructor] Hi again, and welcome to the next video…of the last section,…bulk image resizing and format conversion.…In the previous video…we've seen about user administration scripts.…This video will discuss…how to use scripts for image management.…All of use digital cameras and download photos…from the cameras as well as the internet.…When we need to deal with a large number of image files…we can use scripts to easily perform actions…on the files in bulk.…A regular task we come across with photos…is resizing the file.…Also format conversion from one image format to another…comes with use, for example, jpg to png conversion.…
When we download pictures from our camera,…the large resolution pictures take a large size,…but we may need pictures of lower sizes…that are convenient to store and email over the internet.…Hence we resize it to lower resolutions.…We'll use the command convert from the imagemagick suite,…which contains excellent tools for manipulating images…that work across several image formats…and different constructs with rich options.…
