Exporting Images and Copying Selections to the Clipboard
You can save images of echograms and cruisetracks either by exporting them as image files (including the color legend), or copying them onto the clipboard as a bitmap.
Refer to the options on the Export to Image dialog box (also ExportEchogramToImageCustom via COM) for customizing single beam echogram image exports. The image dimensions for JPEG exports cannot exceed 32,000 pixels.
Note: Echoview renders an integer number of pixels per ping. If the requested image width would require fractional pixels-per-ping, the exported width is increased to the next whole-pixel multiple. For a one-to-one result (one pixel per ping/sample), use Export one pixel per sample in the Export to Image dialog box or call ExportEchogramToImageCustom with WidthInPixels = -1 and/or HeightInPixels = -1.
When exporting echograms to an image, whether from the Echogram menu or through COM commands, the same export logic is applied to ensure consistent results.
Exporting to an image file
Echograms
Single beam
- Click on an open echogram.
- Select the Echogram menu, Export, To Image, then choose Visible echogram... or Whole echogram....
- - or -
- Select a region or make a selection using a Selection tool.
- On the Shortcut (right-click) menu, point to Export Region/Export Selection, then click To Image...
- Customize your export using the Export to Image dialog box and click Export...
- Choose the file export format (PNG, JPEG, TIFF or bitmap) from the Save as type drop-down menu in the explorer window.
Exports of single beam echograms respect line referencing. When a line reference is applied, Echoview adjusts the export extents so the referenced region remains visible.
Multibeam
- Make a selection using a Selection tool.
- On the Shortcut (right-click) menu, point to Export Selection, then click To Image File...
- Choose the file export format (PNG, JPEG, TIFF or bitmap) from the Save as type drop-down menu in the explorer window.
Cruisetracks
To export a cruisetrack/alongtrack display to an image file:
- Click on an open cruisetrack.
- Select the Cruisetrack menu, then click Export Window to Image File...
- - or -
- On the Shortcut (right-click) menu, point to Export Window, then click To Image File...
- - or -

- Choose the file export format (PNG, JPEG, TIFF or bitmap) from the Save as type dropdown menu in the explorer window.
Georeferencing information exported with the cruisetracks
When you export a selection from a cruisetrack, Echoview may also export georeferencing information.
