3.2. Corelyzer Preferences

To launch Corelyzer, double-click on the Corelyzer icon. If you're launching Corelyzer for the first time, the Corelyzer Preferences dialog will appear, in which you can specify your scratch disk location, display settings, and user interface features.

3.2.1. Directories Panel

Image Block Directory: The first time you load a core section image, Corelyzer processes that image into a series of "blocks": sub-images at low, medium, and high resolutions. This processing is done in order to improve performance. Because this initial processing takes a fair amount of time, the "blocks" are stored locally in this directory for future use. Download Directory: In this directory, Corelyzer stores local copies of images downloaded from remote servers.

3.2.2. Display Preferences

Here you can set the display configuration that Corelyzer will use. More often than not you will have it match the display configuration you setup with your operating system (See above sections). After establishing inital settings, Corelyzer will load the saved configurations on future launches without popping up the preferences window.

  • Rows, Columns: define how many monitors do you have and how they are arranged.

  • Screen Width, Screen Height: define the size of a single monitor in pixels. If you start the Preferences configuration for the first time, the full screen dimension will be used.

  • Screen DPI X, Screen DPI Y: DPI stands for "dots per inch". These defines the mapping from pixels to physical measurement. In most cases, you can leave them as default values.

  • Column Offset, Row Offset: Defines the offsets of the visualization area from the origin (upper-left corner of the primary monitor).

  • Border Tickness: The visualization takes into account the monitor border in tiled displays setup. In most cases, you can leave them with the default values.

3.2.3. User Interface Preferences

  • Auto check version in startup: Corelyzer will automatically check for a newer version of the software at launch.

  • Lock depth of core section images after loading: cores loaded while this option is enabled cannot be moved up or down stratigraphically.

  • Use Quaqua look and feel: when enabled, makes user interface elements like buttons and checkboxes look more "Mac-like" in OS X 10.3 and earlier.

  • Double-clicking section name zooms to that section: double-clicking the section name in the session/iCores window shows the entire section at the highest zoom level that can accommodate its length.

  • Show crosshair at origin: show the visualization canvas' origin axes.

  • Show labels for sections with data but no image: show section label for dummy sections (those with plotted data but no image).

  • Canvas always draws below external application windows: windows of non-Corelyzer applications will always draw below the visualization canvas. We recommend disabling this option.

  • Scroll wheel/gesture zooms in Vertical Depth Mode: in Vertical Depth Mode, scroll wheel or gesture will zoom/unzoom when this option is enabled. If disabled, they will pan along the depth axis.

  • Horizontal or Vertical Depth Mode: defines the depth orientation. In Horizontal Depth Mode, depth increases from left to right. In Vertical Depth Mode, depth increases from top to bottom.

  • Canvas background color: defines the background color of the visualization canvas.

  • Canvas grid: enable/disable and defines the background measurement grid parameters. In "Grid Type", 5 types of grid are supported: Basic Cross, Horizontal Lines, Vertical Lines, Points and Cross Points.
