Image Info REALbasic Classes

Image Info is a REALbasic class for retrieving information about images. Because it does not need to open entire images, it returns the info very quickly. Applications can be built to run on PPC, Carbon (OS X) and Windows.

Image Info reads all info from the data fork of files, so files without resource forks (i.e. files from PC platforms) are fully readable. (However Image Info does check for the presence of resources if any given info is not found in the data fork.)

Image Info determines file types (whether "TIFF", "JPEG" etc) by reading the header info. This means that files types accidently edited or corrupted or files from non-Mac platforms can be read safely.
