Expect a descriptive message and an exit status of 1 if any exception occurs such as improper syntax, a problem reading or writing an image, or any other problem that prevents the command from completing successfully. The ImageMagick command-line tools exit with a status of 0 if the command line arguments have a proper syntax and no problems are encountered. For instance, if you need to process an image dynamically from a web script or apply the same operations to multiple images, or if you need to repeat a specific operation on the same or different images at different times, using a command-line utility like ImageMagick may be more efficient. While many people are used to using graphical user interfaces (GUIs) like Gimp or Photoshop to edit images individually, these tools may not always be practical. If you are trying to run FTP through the GUI, you may need to install the FTP client through brew install inetutils.ImageMagick is a collection of command-line tools that can be used to modify and manipulate images. If using an X-window (optional), ensure that the X-directory location (usually /opt/X11/bin) in file default_exec points to the location of xterm, which can be determined from the command which xterm. Never run the model from the guicode directory. The desktop app also runs the model from the same working directory. If the softlink does not exist, one should be created in the working directory using the command ln -s. hysplit.tcl and the GUI should open if Tcl/Tk has been installed. Once the installation is complete, HYSPLIT can be started from the desktop app or by opening a terminal window or X-window and changing directory to hysplit/working. Go to the Google Earth web site to download the most recent Mac version. A system reboot may be required after installation. More information about these displays can be found in the Python section. If the Python display programs are provided with your HYSPLIT distribution, you will find detailed installation instructions in the python directory (e.g. To use them a Python emulator is required. These programs are still undergoing modifications to their capabilities and interface requirements. When finished, enable security again.Ī new class of display programs for trajectories and air concentration contours using the Python language has been developed. If this option is unavailable or multiple apps are affected, you may need to run sudo spctl -master-disable from the terminal before going back to the security and privacy menu. If the installation fails because permission is denied for an unidentified developer, then Open Anyway, or better, if available, go to System Preferences and then Security & Privacy and check the box to Allow apps downloaded from: Anywhere. This will copy the hysplit directory to your $HOME directory (/Users/account/hysplit) and place the hysplit.app on your desktop. This is accomplished through the splitsvg program provided with the HYSPLIT distribution.ĭownload and open the installation package ( hysplit_v5.2.0.dmg) and then run the Install_hysplit.app. Conversion by ImageMagick to other formats requires that the individual frames (within the SVG tags) are written to individual SVG files. Note that all HYSPLIT SVG graphic frames are packaged within a single HTML file. Go to the ImageMagick web site to download the most recent Mac version. ImageMagick can then be used to convert these files to unsupported formats. However, on MAC systems the Preview function can also be used to export SVG to a select number of formats. The capability to convert SVG to other graphical formats is enabled within the GUI through ImageMagick. Install the software to the suggested default directory prior to installing HYSPLIT. If not already installed, you can download Tcl/Tk from the Tcl/Tk web site. Most Unix / Linux operating system distributions, as well as Mac OS X, include Tcl/Tk. The HYSPLIT installation includes all the GUI scripts, but the Tcl/Tk interpreter is not part of the distribution. However, it is easier for novice users to use the Tcl/Tk interface. The model can also be run using a command line interface. Starting with HYSPLIT v5.2.0, the graphical user interface only requires Tcl/Tk because the Postscript graphics have been replaced by Scalable Vector Graphics (SVG) which can be displayed through any browser.Īlthough not required to run HYSPLIT, a GUI composed of multiple Tcl/Tk scripts is provided with HYSPLIT. The HYSPLIT Mac installation is similar to a Windows PC.
