Export current view

Using Eye4Software Hydromagic, it is possible to save your current map view (including overlays like soundings,
boundaries, raw data, waypoints and comments) as an image file.

The software can also generate the world and projection files for you, so you will be able to load the image file directly in
other GPS or GIS mapping software, without the need to calibrate the map.


Exporting the view

In order to export the current map view as an image file, select "Export" => "Export Current View..." from the "File" menu.

Export current view as image file


Export current view dialog

After a few seconds (time needed to capture the image), the following dialog should appear:

Export current map view as image file


Output file format

Before selecting an output file, select the image format you want to use to save the image file.
Hydromagic can store images in one of the following file formats:

Select the image file format


Output file

First, you have to select the output format and the file name of the image file.
After selecting the format, use the "Browse..." button to select the folder and file name.
When you have selected a file that already exists, the software will ask whether you want to overwrite this file.

Select the image file location


Generate World File

In cases where you want to import the exported image file into another GPS or GIS mapping software product, you have to enable this option.
The software stores the upper-left coordinates and the pixel sizes (scale) in the world file.

Depending on the image format you are using, the world file will have the following file extension:

3.726715
0 
0 
-3.726715 
242435.599588 
476855.346680

Projection Files

The software can generate a ESRI WKT or PROJ.4 projection file for you. Together with a world file for geo-referencing the image,
this enables the screen shot to be imported in most GPS/GIS software packages.

The generated projection file will always have the ".prj" extension, irrespective of the selected format.

Adding a map footer

It is possible to add a map footer to the exported image, which is also done when printing the screen.
To select whether the map footer is included, and how the fields are filled, click the "Map Footer Options..." button.

Set the map footer for the exported image file


Exporting the map

Just click "OK" to start the export. The software will now write the selected files. You can monitor the progress in the status bar at the bottom of the screen.
Depending on whether you checked the "Show image after export" the created image will be shown in the Windows Photo Viewer.
