What follows are hints and tips which can be used while working with the Apple Scanner.
General Information
The most common problem users may have is a system error when saving a file that has been scanned. This occurs when the current brightness and contrast settings or half-tone pattern name exceeds 17 characters, usually because the default setting name "Untitled Settings" is saved. The next time changes are made to the brightness or contrast, the settings' name changes to "Untitled Settings 2", which violates the rule. Delete all setting names that are too long fixes the problem.
AppleScan can save data in the PICT, TIFF, and Paint file formats. However, if a document is saved in the TIFF format and changes are made to the file, a "Do you want to save changes?" prompt appears when the document is closed. If changes are saved, the file type changes to PICT format. This is a known problem.
If the user quits AppleScan with the Remote Scan option selected and then goes to HyperScan and clicks on the Preview or Scan button, the scanning will not start until the Remote button on the Apple Scanner is pressed. Remote scanning is not reset when quitting AppleScan but is reset when AppleScan is started. This, too, is a known problem.
Cutting and Pasting
AppleScan fully supports cut-and-paste to the Clipboard and other AppleScan documents. Grayscale data, however, cannot be intermixed with line art or halftones in the same document. It is okay, however, to have line art and halftones in the same document.
A neat feature is to copy a region of a document, then use the selector tool to select a differently sized region, and paste into the region. This works best with Grayscale data.
Pasting with the Tab key held down invokes a transparent paste.
AppleScan is not intended to be an "integrator" of data from other sources. Data from other programs (text, Paint, or PICT), when pasted into AppleScan, does not behave like it would in a MacDraw-type environment, and using AppleScan in this way is not recommended. Instead, AppleScan should be used as a source of scanned data, which is then moved to other applications that are better suited for those tasks. It should be noted that pasting data from MacDraw II creates a strange effect on the Macintosh screen, but does not appear to cause a fatal error.
