AnnotationSketch code examples
Using AnnotationSketch to draw annotations from a file
The following code examples (in C and Lua) illustrate how to produce an image from a given GFF3 file using 
AnnotationSketch. The result is shown in Fig. 
7. In essence, these code examples implement something like a simple version of the 
gt sketch tool from 
GenomeTools without most command-line options.
C code
(See 
src/examples/sketch_parsed.c in the source distribution.)
Lua code
(See 
gtscripts/sketch_parsed.lua in the source distribution. This example can be run by the command line 
gt gtscripts/sketch_parsed.lua <style_file> <PNG_file> <GFF3_file>)
Ruby code
(See 
gtruby/sketch_parsed.rb in the source distribution.)
Python code
(See 
gtpython/sketch_parsed.py in the source distribution.)
Using AnnotationSketch to draw user-generated annotations
The following C code example illustrates how to produce an image from annotation graphs created by user code.
 The result is shown in Fig. 
8.
