ImageMagick - manipulate images with command lines
ImageMagicK is a utility that allows users to manipulate images with command lines. While most imaging software have elaborate graphical user interfaces with plenty of special effects to choose from, ImageMagick can perform operations on the image from the command line. This utility is particularly useful for projects where there is a need to automate work on images. ImageMagick is available for Windows and Linux operating systems. With ImageMagick, an image can be converted from one format to another or a text can be added to the image from the command line.
ImageMagick is a powerful command line tool that allows you to manipulate images.
The advantage of this tool is that it allows:
Automated work on images (this avoids having to do some manipulation in Photoshop or Gimp).
Implement operations and conversion of a blow to hundreds of images at once.
To convert between different image formats
To create images on the go
To be incorporated into your programs and scripts (this allows your programs and scripts to generate and manipulate images on the fly). For example, it is usable with PHP to generate images.
This program is available for Windows and Linux.
Install ImageMagick on Windows:
1. Download ImageMagick
2. Install it. During installation, be sure to properly check the "Update executable search path"
3. Close and re-open your session (or restart the computer). This step is necessary for the path (PATH) ImageMagick to be taken into account.
To verify the installation, open an MS-DOS window and type: convert--version
