Preferences: Images

Purpose

Use Images preferences to customize how images are opened, displayed, and saved in NeuroInfo.

Access Images preferences from File > Preferences > Images.

Open

Enable smart optimize for images with low signal: When enabled (checked), image display is automatically optimized if low signal is detected when opening files. Note that, if you're opening multiple image files, you can cancel the smart optimize operation by hitting the Esc key on your keyboard and choosing to cancel when prompted.

Zoom to fit on load:

  • When enabled (checked), the image and/or tracing is automatically sized to fill the window while preserving the aspect ratio.

    • With manually placed reference point: The top left corner of any opened image is placed at the top left corner of the viewing area regardless of where the reference point is. The image will then be centered and resized to fill as much of the viewing area as possible.

    • No reference point: The top left corner of the first opened image is placed in the top left corner of the viewing area and the reference point is automatically placed at the top left corner of the image. The image is then centered and resized to fill as much of viewing area as possible. The reference point will also move and remain aligned with the top left corner of image. The top left corner of the second opened image will also be placed at the top left corner of the viewing area, then be centered and resized. However, since the reference point was no longer in the top left corner of the viewing area, the top left corner of the second image will not be aligned with the reference point. This will be the case for all subsequently opened images.

  • When disabled (unchecked), the image and/or tracing is displayed using the reference point as the origin.

    • With manually placed reference point: The top left corner of any opened image will be placed at the top left corner of the viewing area regardless of where the reference point is located.

    • No reference point: The top left corner of the first opened image is placed at top left corner of viewing area and the reference point is automatically placed at the top left corner of the image. All subsequent images will be placed at top left corner of the viewing area regardless of where the reference point is located.

The reference point is the origin (0,0,0) of a data file. Each data file contains a single reference point and tracing data are calculated and saved relative to the reference point.

Note that if opening a data file with existing images and/or tracings, they will be placed in the same location relative to the reference point as they were when the file was last open.

Load all stacks at same Z: 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 compared to the first image. Check the box to load all image stacks at the same Z position.

Show Image Scaling dialog on opening image: By default, NeuroInfo displays the Image Scaling dialog only when it cannot identify scaling. Check the box to display the dialog every time you open an image. This may be useful when:

  • You want to verify the image scaling values.

  • Images have been saved with inaccurate image scaling that needs to be corrected.

  • You want to use the image file scaling values to create a new software lens.

Enable resampling quality bias: This is an advanced feature that we recommend keeping disabled (unchecked) for the most part. Our Technical Services staff may recommend enabling it to increase the quality of image-data display. Enabling resampling quality bias, however, will decrease the speed of image loading.

Luminance

Save extended component data: (relevant primarily for brightfield images) Check to save data about the RGB components of the image.
