Export to Image dialog box

Echoview opens this dialog box when you Export from an echogram to an image file. Use these settings to customize your image export.

Select horizontal extents
Select vertical extents
Split export across multiple images
Acoustic data image dimensions

Select horizontal extents

Customizing these settings will override the default ping range of the export echogram, region or selection.

All pings

Export all pings in the echogram.

Ping range

Specify the range of ping numbers.

The default values are the ping range of the echogram, selection or region.

Time range

Specify the time range (yyyy-MM-dd HH:mm:ss.sss) of the pings.

The default values are the time ranges encompassing the pings of the echogram, selection or region.

If you enter either the date or time, Echoview will attempt to autocomplete the entry to the required format based on your partial input.

Select vertical extents

Customizing these settings will override the default depth or range of the export echogram, region or selection.

All samples

Export all the samples for each ping.

Depth

Specify the depth (meters) interval for the column of ping samples.

The default values are the start and stop depths of the echogram, selection or region.

Range

Specify the range (meters) interval for the column of ping samples.

The default values are the start and stop ranges of the echogram, selection or region.

Split export across multiple images

Export as single image	Default.
Split images by ping	Specify the Target number of pings per image. Typically, the final image in the sequence will comprise fewer pings. Refer to File naming sequence below.
Split images by time (hours)	Specify the Target time span of pings in decimal hours. Typically, the final image in the sequence will comprise a shorter time span of pings. Refer to File naming sequence below.

File naming sequence

When Split is selected, exported image files are saved using the file name you provide together with a zero-padded numeric suffix (e.g., _0001, _0002, _0003). The suffix numbering always starts at _0001, even when only a single image is produced. This ensures consistent naming for automated workflows.

Note: When Split is selected, each exported image uses the requested height. The width may differ from the requested value due to the pixels-per-ping rule (see footnote 1), and the final image may be narrower depending on the remaining pings/time.

Acoustic data image dimensions

The settings in this section apply to the image size of the echogram area only. If you include optional UI elements (e.g., color legend, GPS/position status bar), their fixed pixel heights are added to the requested echogram height. If those elements are not displayed, they are not added.

Export one pixel per sample

Default. These values are immutable and correspond to the dimensions of the export echogram, region or selection.

Use custom image dimensions

Specify the resolution in pixels (up to 32,000 pixels for JPEG).

Selecting this presents the Maintain echogram aspect ratio option. Enable this checkbox to fix the Image width relative to the Image height of your choice¹.

Note: Maintain echogram aspect ratio is a user-interface setting only; it is not a parameter of COM exports.

You need an Image height of at least 200 pixels to export the color legend in the image.

¹Expect some variation in the exported width. The exporter guarantees an integer number of pixels per ping; if the requested width would require fractional pixels-per-ping, the width is increased to the next multiple (e.g., 500 px requested for 415 pings becomes 830 px). Height is exact unless the color legend or GPS/position status bar is included, in which case those elements add fixed extra pixels.
