Parameters
GIMAGE file
 
Purpose

  Read bitmapped images.
  The main purpose is to pick up data points from scanned diagrams

Function

  The specified file is read and interpreted as a bitmapped graphic picture.
  A subsequent GDISP displays the picture and allows to define the x- and y-axis
  using a cursor rectangle.
  You have to explicitly specify the lower and upper limits as well as linear or log scale.
  Once the axes are completely defined you can apply other gd commands for further processing

Remark
 
Example


  GIMAGE file.iff
  GDISP / XMIN(0) XMAX(10) YMIN(1) YMAX(100) YLO
  GPOS / LOOP
  GSAVE  file.gd


  reads the image data, defines the x- and y-axis (log).
  With GPOS data points can be picked up and their coordinates
  are saved to file.gd

Name of a bitmapped graphics file. The particular format is determined
from the file name extension. Currently supported are:

.iff   Amiga IFF-ILBM (big-endian systems only)
.xbm   X11 bitmap (UNIX systems only)
