10139N/A<para>The <command>&cmd;</command> command shows how to use the SubIFD tag

10139N/A(#330) to store thumbnail images. <command>&cmd;</command> copies a TIFF Class

10139N/AF facsimile file to the output file and, for each image, an 8-bit grayscale

10139N/Athumbnail sketch. The output file contains the thumbnail image with the associated

10139N/Afull-resolution page linked below with the SubIFD tag.</para>

10139N/A<para>By default, thumbnail images are 216 pixels wide by 274 pixels high.

10139N/APixels are calculated by sampling and filtering the input image with each

10139N/Apixel value passed through a contrast curve.</para>
