+ *
+ * miGIF compression uses run length encoding. It compresses horizontal runs
+ * of pixels of the same color. This type of compression gives good results
+ * on images with many runs, for example images with lines, text and solid
+ * shapes on a solid-colored background. It gives little or no compression
+ * on images with few runs, for example digital or scanned photos.

-DESCRIPTION
+gd is a graphics library. It allows your code to quickly draw images
+complete with lines, arcs, text, multiple colors, cut and paste from
+other images, and flood fills, and write out the result as a PNG, GIF
+or JPEG file. This is particularly useful in World Wide Web applications,
+where PNG, GIF and JPEG are three of the formats accepted for inline
+images by most browsers.
- gd is a graphics library. It allows your code to quickly draw images
- complete with lines, arcs, text, multiple colors, cut and paste from
- other images, and flood fills, and write out the result as a .PNG file.
- This is particularly useful in World Wide Web applications, where .PNG
- is the format used for inline images.
-
- gd is not a paint program. If you are looking for a paint program, you
- are looking in the wrong place. If you are not a programmer, you are
- looking in the wrong place.
-
- gd does not provide for every possible desirable graphics operation.
- It is not necessary or desirable for gd to become a kitchen-sink
- graphics package, but version 1.7.3 incorporates most of the commonly
- requested features for an 8-bit 2D package. Support for truecolor
- images, JPEG and truecolor PNG is planned for version 2.0.
-
-AUTHOR
- gd was written by Thomas Boutell and is currently distributed by
- boutell.com, Inc.
+gd does not provide for every possible desirable graphics operation,
+but version 2.0 does include most frequently requested features,
+including both truecolor and palette images, resampling (smooth
+resizing of truecolor images) and so forth.
