Handling Images from the Command Line

Recently, I needed to do some work from the Windows Command Line, and I needed to deal with a few images. Along the way, I found some great tools. All these tools are free. Can come in useful when automating.

Manipulation

ImageMagick – This is a collection of command line tools. You can do image conversion, view properties, transform, transparency, join, overlay, add special special effects, and tons more. Also has APIs for C, C++, Java, .NET, Perl, PHP, Python, Ruby, and others. Highly recommend it.

Screen Capture

CmdCapture – Takes a screenshot of your desktop from the command line.

IECapt – Capture Internet Explorer’s rendering of a web page into a BMP, JPEG or PNG image file.

Cutycapt – Capture WebKit’s rendering of a web page into a variety of vector and bitmap formats, including SVG, PDF, PS, PNG, JPEG, TIFF, GIF, and BMP.

wkhtmltopdf – Convert HTML to PDF using the Webkit rendering engine, and Qt.
