Preferences: Images

By default, the program only displays the Image Scaling dialog when it cannot identify scaling. Also see Image scaling

These options provide you with options to improve the display of your image when the program is unable to identify the bit depth.

Bit depth only affects the display of the image, not the underlying data.

• When selected, the image and/or tracing is automatically sized to fill the window while preserving the aspect ratio.
• When unchecked, the image and/or tracing is displayed using the reference point as the origin.

Select when working with single-channel images requiring false coloring.

If left unchecked, image stacks are loaded with the first image at the current Z position, with the images in the stack placed at regular intervals in Z from the first image.

Useful to identify the current image.

Alternative method: Use the Image Organizer; the current image is identified by a blue highlight for the image information.

Displays the Image File Reader Channel Colors dialog box.

Use with multichannel image files that don't contain color specifications (e.g., Nikon IDS/ICS files) to assign colors to display.

When checked, the acquired and imported image thumbnails are shown in their appropriate locations in Where Is mode.

Affects the viewing of Image Processing effects. If this option is checked, the preview area will disappear after an Image Processing effect has been applied. It can be turned back on by checking the Preview box in the Image Processing dialog box.

This option affects the viewing of Image Processing. If this option is checked, a preview window automatically appears whenever a new image Processing effect is selected.

Acquires "n" images and averages these "n" acquisitions into a single image. Use this option if your camera generates a lot of noise in the image.

Number of images to use: Start with a small number and gradually increase until the noise reduction is satisfactory.

Select to automatically save the acquired images to a defined path.

Optional: Use a base name. As each image is saved, the program uses the base name and a number that increments by 1.

Use this option to use configuration files separate from image files. MBF-specific information includes data about the Data DIB, Display DIB, and other information about the image file and how the program should process it.

Use this option to use configuration files separate from image files. Adjustments are saved in a separate file to avoid modifying the image.

Sometimes the shapes of objects displayed on the monitor don’t seem to be an accurate representation of their actual (or expected) shapes. The perceived inaccuracy depends on how much the aspect ratio of the image file varies from the aspect ratio of the display monitor.

For most images, the option use aspect ratio of current image results in a satisfactory representation of the objects. This is because the aspect ratio of the pixels in the image file and the aspect ratio of the pixels in the display monitor are very similar.

But if there is a significant difference between the aspect ratio of the pixels in the image file and the aspect ratio of the pixels of the display monitor, the option use aspect ratio of current imageresults in an image with seemingly distorted (stretched or compacted) objects in one dimension. Apparent image distortion is most likely to occur when displaying MRI images because, while some MRI images have aspect ratios significantly different from 1.0, most display monitors have a pixel aspect ratio close to 1.0.

To resolve the apparent image distortion, use the option use aspect ratio of current lens and define a suitable lens:

1. Select use aspect ratio of current lens.
2. Define a lens that matches the aspect ratio of the pixels of your display (likely to be close to 1.0).

 

All measurements reported by the program are correct regardless of the option selected (and even if the image appears distorted) .
