Exporting Images

You can export image data from the Data Properties and Settings panel to a number of different file formats, including RAW, TIFF, BMP, JPEG, PNG, and other formats (see Supported File Formats for information about the file formats available in Dragonfly for exporting).

You can also export images in the ORS Object (*.ORSObject extension) file format (see Exporting Objects).

Save As dialog options

The following options are available in the Save As dialog when you export images:

Apply W/L and gamma

If selected, the window leveling settings and gamma value you selected for reviewing images will be applied to exported image data.

Note This option is only available for Dragonfly Pro. Contact Object Research Systems for information about the availability of this version of Dragonfly.

RAW options

Saves images or stacks as raw pixel data without a header. Suitable for transferring files between applications and computer platforms. Note When saving RAW files in Dragonfly, header information is saved in an accompanying DAT file.

TIFF options

The additional options for saving images in the TIFF file format include the following:

Use LZW compression… If selected, LZW compression will be applied to exported TIFFs. You should note that LZW, invented by Abraham Lempel, Jacob Ziv, and Terry Welch, is a lossless compression method. That means that no data will be lost in compression, unlike a lossy format like JPG. You can open and save a TIFF file as many times you like without degrading the image.

Output all images into one file… If selected, all images in a volumetric dataset will be output into a single file. If not selected, a separate file for each slice in the TIFF stack will be created.

JPEG options

The additional options for saving images in the JPEG file format include the following:

JPEG image quality… The JPG format is lossy compressed according to a quality value, which can range from 100 — the highest quality, but also the largest file size — down to 1, which creates a poor quality, small file.
Image spacing values for the third dimension (Z) are not retained when exporting to the TIFF file format. You should also note that image spacing is not retained for any dimension when exporting to BMP, JPEG, or PNG.
The Save As options are not available for Linux versions of Dragonfly.
