Exporting Images
You can export image data from the Data Properties and Settings panel to a number of standard file formats, including RAW, TIFF, BMP, JPEG, PNG.
Right-click the image data you want to export in the Data Properties and Settings panel and then choose Export > Image in the pop-up menu to open the Save As dialog. The Save As dialog includes additional options for exporting images, as shown below.
Save As dialog options
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. You should note that this option is only available for Dragonfly 3D World ZEISS edition. Contact Comet Technologies Canada Inc. for information about the availability of this version of Dragonfly.
The following additional options are available in the Save As dialog when you export images:
| Description | |
|---|---|
| RAW options |
Saves images 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. Note Image spacing values are retained when exporting to the TIFF file format, but is not retained when exporting to BMP, JPEG, or PNG. |
| 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. |
