+The following image files are included for testing.  Note that a wide
+variety of images can be generated using the tools provided with the
+library (e.g. tiffcp, tiff2bw, tiffmedian, etc.); see below for some
+hints on this.
+
+PlanarConfiguration = 1 (packed data)
+-------------------------------------
+caspian.tif	279x220 64-bit floating point (deflate) Caspian Sea from space
+cramps.tif	800x607 8-bit b&w (packbits) "cramps poster"
+cramps-tile.tif	256x256 tiled version of cramps.tif (no compression)
+dscf0013.tif	640x480 YCbCr digital camera image which lacks Reference
+		Black/White values. Contains EXIF SubIFD. No compression.
+fax2d.tif	1728x1082 1-bit b&w (G3/2D) facsimile
+g3test.g3	raw Group 3 encoded fax file
+g3test.tif	TIFF equivalent of g3test.g3 created by fax2tiff
+jello.tif	256x192 8-bit RGB (lzw palette) Paul Heckbert "jello"
+ladoga.tif	158x118 16-bit unsigned, single band, deflate
+off_l16.tif	333x225 8-bit CIE LogL (SGILog) office from Greg Larson
+off_luv24.tif	333x225 8-bit CIE LogLuv (SGILog24) office from " "
+off_luv32.tif	333x225	8-bit CIE LogLuv (SGILog) office from " "
+pc260001.tif	640x480 8-bit RGB digital camera image. Contains EXIF SubIFD.
+		No compression.
+quad-jpeg.tif	512x384 8-bit YCbCr (jpeg) version of quad-lzw.tif
+quad-lzw.tif	512x384 8-bit RGB (lzw) "quadric surfaces"
+quad-tile.tif	512x384 tiled version of quad-lzw.tif (lzw)
+strike.tif	256x200 8-bit RGBA (lzw) "bowling pins" from Pixar
+text.tif	1512x359 4-bit b&w (thunderscan) am-express credit card
+ycbcr-cat.tif	250x325 8-bit YCbCr (lzw) "kitty" created by rgb2ycbcr
+
+smallliz.tif	160x160 8-bit YCbCr (OLD jpeg) lizard from HP**
+zackthecat.tif	234x213 8-bit YCbCr (OLD jpeg) tiled "ZackTheCat" from NeXT**
+
+** These images are in a deprecated format and are included only for testing
+   backwards compatibility.  JPEG-encoded TIFF images use a different scheme
+   described in TIFF Technical Note #2 and implemented by libtiff.
+
+PlanarConfiguration = 2 (separated samples)
+-------------------------------------------
+oxford.tif	601x81 8-bit RGB (lzw) screendump off oxford
+
+The other images are from Hewlett Packard and exemplify the use of the
+HalftoneHints tag (in their words):
+
+The images are all the same subject, and should all appear the same
+after rendering.  Each of the images is slightly different as outlined
+by the following table:
+
+   FileName	   ToneRange  HalftoneHints
+jim___cg.tif      	A	    Y
+jim___dg.tif      	B	    N
+jim___gg.tif      	B	    Y
+
+The images with tone range A are 0-100% linear reflectance images,
+in other words, fixed full gamut tone range.  The images with tone
+range B are what we call "normalized", meaning that the image has
+been tone adjusted such the Highlight and Shadow are at gray levels
+1 & 2**BitsPerSample-2.
+
+Each of the three grayscale images should be rendered to look like
+the halftone in pics/jim___ah.tif when printed on a Canon SX engine.
+
+Generated Images
+----------------
+The file g3test.tif was created from g3test.g3 with the command:
+
+    fax2tiff -o t.tif -1 -p -M -R 98 g3test.g3
+
+Tiled images can be created with tiffcp; e.g.
+
+    tiffcp -t -c none cramps.tif cramps-tile.tif
+
+(but the tiled images included here were actually generated by the
+Silicon Graphics Image Library).
+
+The file quad-jpeg.tif was created from quad-lzw.tif with the command:
+
+    tiffcp -c jpeg quad-lzw.tif quad-jpeg.tif
+
+To generate a tiled image with separated samples the following might
+be used:
+
+    tiffcp -t -p separate quad-lzw.tif t.tif
+
+[ Beware that tiffcp does not handle every format TIFF image.  In particular,
+  when conversion between tiled and strip'd images is reliable only when
+  BitsPerSample is 8. ]
+
+To generate a G4-encoded image with a single strip the following would work:
+
+    tiffcp -c g4 -r 1082 fax2d.tif t.tif
+
+Contributing New Images
+-----------------------
+If you have images that are significantly different from those included
+in this package and that do NOT HAVE A COPYRIGHT; feel free to send them
+to me at sam@engr.sgi.com.  I prefer to receive a URL to a location from
+which I can retrieve the image by public FTP.  However if that is not
+possible you can send it to me in a mail message uuencode'd.  Please do
+not send large images by mail.  Also, please do not send me an image
+unless it is notably unique; e.g. not easily generated using the tools
+I provide.
