Ch. 9 - Using SPOT DatabasesImage File FormatFrom the Preferences window, you can define the graphic format of the images saved to a database. Thereare six options:• Windows Bitmap• JPEG (allows for image compression)• JPEG2000 (allows for image compression)• Mac PICT• TIFF Uncompressed• TIFF JPEG (allows for image compression)Windows Bitmap is the default option. To defineimage file format, select one of the formats fromthe drop-down list. Selecting either the JPEG or the TIFF JPEG option activates the JPEG Quality box.This option allows you to compress images (i.e., lower their resolution) so that you can save disk space incases where high-resolution images are not needed.To define JPEG Quality, select a value between 1 and 100:• A value of 1 represents the lowest resolution and the smallest file size.• A value of 100 represents the highest resolution and the largest file size.For JPEG2000 Quality, select between lossless (minimal compression) and lossy. Select a ratio for lossycompression. A higher number equates to greater compression with greater chance of data loss.Thumbnail Save PreferenceDetermine whether you will Save Image Thumbnails for the database. The Save Image Thumbnailsoption saves a thumbnail of each image in the database. This allows you to visually browse through theimages in a database. You can also open a database image from a thumbnail.CAUTION!When you select the Save Image Thumbnails option, the thumbnail images are saved to the SPOTdatabase file, which resides on your hard drive at C:\Spotcam\Database\[name of your database].db.Each thumbnail increases the size of the database file by approximately 6 Kb.Defining Database FieldsThe Database Fields window is a centralized point for defining thedetails associated with a database. There are three processesassociated with the definition of database fields:• Naming and defining Text/Numeric Fields – Thetextual/numeric fields that you define represent the data youwant to be associated with an image. Typical text fields includepatient name and ID number. Typical numeric fields includeheight and weight.• Naming and defining Lookup Fields– Lookup fields alsorepresent data that you want to be associated with an image.Lookup fields are used in cases where the data item has a limitednumber of discrete options (e.g., blood type). Each lookup field is associated with a user-defined listof items, enabling you to select an option from a list, as opposed to manually entering it each time animage is saved to the database.• Setting Default Values for the fields – To speed the process of saving images to a database, you candefine default values to automatically appear for a field. This helps you to avoid multiple entries of thesame item when numerous images have the same data for a particular field.184 User Guide to the SPOT Insight Camera
