aiSee: Output Split

aiSee employs two different concepts of splitting output images. First, user-defined image parts can be exported to bitmap, PostScript, or SVG formats under the control of some options. Second, large graphs can be automatically split in up to 100 pages for printing or export to PostScript.

Export of image parts

In aiSee 3, use the “Select area” mode to mark any part of the graph and then export it.

Export of image parts from the command line

When exporting a graph with aiSee 3, the command line option --area WxH+X+Y enables an image part to be exported instead of the entire image. The image part is specified by a bounding rectangle with the width W and the height H, while X and Y specify an offset from the graph origin, i.e. from the upper left corner of the layout.

When exporting a graph with aiSee 2, the image part to be exported is specified by a combination of the four command line options -xmin X1 -ymin Y1 -xmax X2 -ymax Y2 (see example).

These options are especially useful for Web-based applications in order to limit the size of output images or to implement a panning or zooming feature, as shown in the example below.

PostScript output split

In aiSee 2, the command line option -split Int automatically splits the output into Int pages. Further options include selecting paper size and customizable page margins (see printer driver options). PostScript files can be transformed into GIF or JPEG by GhostScript. See example graph split into 35 pages.
