The Preferences screen is used to change PixelNEO's global configuration settings that govern how the program works. Typically, once configured properly, you will seldom need to make changes to these items. At the top of the screen are several tabs that you can click to switch between multiple pages of configuration options.


General

The first page contains several general purpose settings that you can use to change PixelNEO's behavior. These are described below:


Brush Cursors

Two styles of Brush Cursors are available. The brush cursor is displayed when the mouse cursor passes over a picture's Drawing Area when using one of the free hand Painting and Drawing Tools (Eraser, Brush, Spray Can, etc.). The Standard style displays the cursor as static icon (shaped like a paint brush, spray can, pencil, etc.). The Precision style displays the cursor as an outline of the actual size and shape that the drawing tool will paint with. Which of these styles you select is primarily a matter of personal preference as both styles produce identical results.


Startup Options

Here you may specify what actions PixelNEO should take each time it is loaded. Choose Open New Blank Picture if you want to start each PixelNEO session with a fresh picture. Select Display File Open Dialog to have PixelNEO display a file open dialog to start each session by selecting an existing picture from your hard drive. Finally, you may choose to have PixelNEO start with a blank screen by selecting Do Nothing.


Miscellaneous

Enable the Resize picture windows when Zooming option to automatically adjust the size of the active picture window to best fit the size of the image. For example, zooming out will reduce the amount of space required on screen to display the image. When this option is enabled, PixelNEO will shrink the picture window to accommodate that change in size. Similarly, when zooming in, PixelNEO will enlarge the window.


When the Show full file Path in picture window's title bar option is checked, PixelNEO will include the file's entire  file name, including drive and path, in the picture's title bar. When this option is disabled, the drive and path will be omitted from the title bar.


Finally, the Number of Items Saved in Recent Files Menu option allows you to specify the maximum number of files names that will appear in the File menu's Reopen list. Set this option to zero to disable the Reopen menu completely.


Save

The When saving a picture with Save As option allows you to modify the behavior of PixelNEO's Save As function by choosing one of the following:


Display all file types and convert the picture if content is incompatible - will allow any file format to be selected regardless of whether that format is capable of handling the contents of the picture. If the format selected lacks some feature found in the picture (such as alpha transparency, layers, etc.) PixelNEO will automatically convert the picture - after asking your permission. Selecting a format that does not support all of the picture's elements can seriously degrade the quality of the image.


Display only file types that are compatible with the picture contents - will limit the selection of file formats to only those that can actually handle the contents of the picture. For example, if the active picture contains multiple layers, then only PixelNEO Layered Graphic (NPG) and a Photoshop™ Document (PSD) will be available since these are the  only formats that support layers.


Enabling the Create Backup Files option will instruct PixelNEO to create a backup copy of the previously saved version of each picture. The file name of the backup will be the same as the original except the extension will be changed to BAK. Should you inadvertently save changes you did not intend to, you can rename the backup file and recover your previously saved version.


The Warn when x Quality is less than... option allows you to be notified before a potentially damaging compression level is applied to a picture. Since JPEG, JPEG 2000 and HDP all use a "lossy" type of compression, a high value can result in a degradation of picture quality. When the quality factor is less than the numbers entered here, you will be warned and given the opportunity to select a new setting before saving.


Undo

PixelNEO includes a dynamic, multi-level Undo/Redo feature that can keep track of multiple changes made to your pictures. This is a convenient feature for recovering from mistakes, however, it does take up memory and may slow your computer when editing large pictures. If you have a slow computer, or one with limited memory, you might wish to turn this feature off to improve performance. Conversely, if you have a fast system with abundant memory, you may want to adjust these settings to take full advantage of your computer's potential.


To do this, you can increase or decrease the number of changes to each open picture that will be stored in the Undo History by entering a value into the Maximum Items in Undo History field. The best choice here can vary depending on a number of factors. If you generally work with small pictures, this value can be quite high without affecting performance. For large pictures, a lower setting will yield improved performance but limit your ability to recover from mistakes. The default settings should be adequate in most cases, so you only should need to change this setting if you are having problems.


Plug-Ins

This option allows you to load Adobe™/Photoshop™ compatible plug-in effect filters. Enable the check box and enter up to three folders on your hard drive where you have plug-ins installed. Compatible plug-in files will have a file name with an .8bf extension.


There are a number of third party commercial and free plug-ins available from various sources on the Internet. However, you should be aware that not all plug-ins are compatible with PixelNEO.


File Types (Windows Vista, 7, 8 only)

If you're using Windows Vista, Windows 7 or Windows 8 then an additional "File Types" tab will be available. Click the Set PixelNEO File Types button to open the Windows Set Program Associations screen. Here you can specify which file types you would like to have associated with PixelNEO. Once an association is made, you can automatically open files of that type with PixelNEO by double clicking their icons in Windows Explorer.


The File Types option is not available with Windows XP.
