time. TIFF (Tagged Image File Format) is the only tiled format that the program
supports. The TIFF reader supports all image types:
Bitonal (1 bit per pixel)
Gray scale and indexed color (8 bits per pixel)
True Color (24 or 32 bits per pixel)
You can save tiled TIFF images with most image scanning tools. The image
tiles should be no smaller than 64 x 64 pixels and no larger than 512 x 512
pixels. Additional file readers that support other tiled formats, such as CALS
Type II, are available from third-party developers.
Suppress Highlighting When Selecting Images
You can turn on or off the highlighting that identifies the selection of a raster
image or the image frame by selecting Highlight Raster Image Frame Only on
the Display tab in the Options dialog box. You can also set theIMAGEHLT
system variable directly. By default, IMAGEHLT is set to 0, to highlight only
the raster image frame. Turning off highlighting of the entire image improves
performance.
