Use these settings to identify a range of resources for export.
The Start ID is the first resource that will be exported and the End ID is the last to be exported.
When this window opens, Start ID is populated with the first resource ID and the End ID with the last resource ID (of resources of the specified type).
The Reference Count is the number of times a resource is used. You can specify a range if desired. For example, if you want to only export resources that are used in the book, put in 1 for At least.
Color Depth refers the how many bits are used to represent each pixel. A JPEG or GIF image imported into ToolBook will typically come in as 24 bits/pixel. For native deployment, this makes the .tbk file unnecessarily large. Saving these images as bitmaps with 8 bits/pixel (256 colors) with an optimized palette in a program like PhotoShop® will make your book much smaller without a noticeable drop in picture quality. If you want to export only bitmap resources with greater than 256 colors, you could select 15 from the At least choice. Notice that this option will be disabled for resource types other than bitmap and icon.
Bitmap Export to allows you to match the extension to the format of the bitmap resource (this is the recommended option) or to export to .bmp, .jpg, .gif, .png, .tif, .wmf, or .emf extensions. Notice that this option will be disabled for resource types other than bitmap.
Bitmap Image formats allows you to pick while type of bitmap resources to export. For example, if you select *.PNG, any bitmap resources that are in PNG format will be exported (assuming they meet the other constraints). If you are publishing to DHTML, you might pick all the *.BMP resources convert them externally to PNG format, and then import them. Notice that this option will be disabled for resource types other than bitmap.
The Size setting allows you to only export bitmaps with a size in a particular range if desired. You might use this if you only want to optimize the palettes for larger bitmap resources, for example. Notice that this option will be disabled for resource types other than bitmap.
