![]() ![]() The prompt will be something like this: ~ Start the "Cygwin64 terminal" by double-clicking the desktop icon. When you want to update the packages you already have, or uninstall packages, or add new ones, run the same setup-x86_64.exe program. and this will work whether typed as a bash or cmd command, in either a Cygwin terminal or Windows console. When environment variables are set as described below, a Cygwin terminal can be started with the command: mintty.exe -i /Cygwin-Terminal.ico. You can also start the Cygwin terminal by typing this at a Windows command prompt: C:\cygwin64\bin\mintty.exe -i /Cygwin-Terminal.ico. For copy-and-paste, use right-mouse-click, or ctrl-ins and shift-ins. ![]() Running this gives a console that looks and operates like a Windows console. If you have installed to somewhere else, adjust the following as required.īy default, it creates a "Cygwin64 terminal" on the desktop. If you want to compile ImageMagick, or build programs with the IM libraries, you probably want the "Devel" package.ĭepending on how much you have selected and your internet speed, download and installation might take between two and ten hours, mostly unattended.īy default, this installs 64-bit Cygwin to the directory C:\cygwin64. "Utils" contains dos2unix.exe and unix2dos.exe which you might find useful for converting text files between Unix and Dos formats. "Graphics" includes "poppler: PDF manipulation utilities", which can be useful. I strongly suggest you do not install ImageMagick from Cygwin. The "graphics" package includes an old version of ImageMagick, v6.7.6-3, when the current official release is v6.8.9-5. You might want the complete "graphics" packages, but beware. You probably want "bc" and "gnuplot", which are in "math", and are not installed by default. This runs as a conventional Windows installation, but you are given the choice of what packages to install. For my 64-bit computer, this downloads and runs setup-x86_64.exe. Install CygwinĬygwin homepage, run the 64-bit or 32-bit installation program. This page assumes you install only the pre-compiled Windows binary. There are complications if you compile it yourself (for example, you might compile the Unix or Windows source). IM's directory should be at the top of this list.Īlternatively, you might compile ImageMagick from source. The command " where convert.exe" will tell you the locations where Windows finds the program. If convert ever gives you an error message like "Invalid Parameter" or "Invalid drive specification" then you are probably running the Microsoft Windows tool convert.exe because IM's convert.exe isn't in a directory on your path. If you are very short on memory, a dll version may use less than a static version.ĭownloading and installing IM takes about five minutes.If you develop and distribute applications, the portable version may be most suitable.If you know that all your images are only 8 bits/channel/pixel, Q8 may be faster and give good-enough quality. For most purposes, Q16 gives better quality than Q8.If your computer is 64-bit, I expect 圆4 will be faster.Must be x86 if your computer is 32-bit.I suggest you add the path to the installation directory to your Windows system path. If you haven't already, you should install the ordinary Windows binary release of ImageMagick from the official How To: Using Cygwin and Scripts (e.g., Fred's) with IM. Information on this page is based on a Cygwin v1.7.30 installation on 16 July 2014 to a 64-bit Windows 8.1 computer, following a query on the ImageMagick forums: (After following the steps given on this page, "man bash" should work from either Cygwin or Windows.) ![]() I will ignore all these except for bash, which will be used for all for all Unix-like examples on this page.įor more information on bash, type "man bash" at the command line.
