"xpsview" is a MOTIF PostScript previewer. "xpsview" uses "psview" to do the rendering of PostScript files (see psview(1)).
You can change the document's bounding box (i.e. visible part) by selecting a region with your mouse an holding down the "SHIFT" key, and revert to the former bounding box using the "Revert" button.
The "Zoom" button zooms the current bounding box out by a factor of 2. This is the only way you can enlarge the initial document's bounding box.
The "Undo" button undoes any change (scale factor, bounding box, viewing mode...).
You can create "Post-It" (psview) windows by selecting a region with your mouse an holding down the "CONTROL" key.
Custom bounding boxes can be added to the file selection dialog using the "PsView.boundingBox" X resource (see psview(1)) using the following format:
PsView.boundingBox: x0 y0 x1 y1 (name) .... x0 y0 x1 y1 (name)
