With PS_View one can obtain page dimensions information and measure the objects visible on the screen.
Two measurement crosses serve to measure document elements. They are being placed onto the screen in turn, by the use of the mouse with its right button pressed. If only one cross is visible, the status bar shows the position of its origin. The measuring cross can be moved as long as the right mouse button is pressed.
When both crosses are visible, the status bar dispalys the distances dx, dy, dz between their origins along with the angles alpha and beta of the diagonals of the rectangle marked by the crosses (cf. Picture 2.2). The measurement results can be recalled with the menu command Grids & Frames -> Measure (Ctrl+M).
The measurement crosses are being deleted at the attempt to add a third cross or by clicking the right mouse button while Ctrl is pressed.
Grids & Frames -> Bounding box (F5) shows the page's bounding box and displays its dimensions in the status bar. If the bounding box is known, the document pages are being displayed in a white rectangle area of the bounding box dimensions placed against a grey background.
Grids & Frames -> Page (F6) shows the page's frame and displays its dimensions in the status bar. The pages frame is normally set with one of the PostScript commands: setpage, setpageparams, setpagedevice or a parameterless command such as a4, a3, letter etc.
Grids & Frames -> Printer (F9) shows the printing frame, i.e., that part of the screen which with the current settings can be printed with the File -> Print command. The printing frame is doubled (the subframes distance is 6 mm) to mark those parts of the document which although fit onto the page but are outside the printing margins of most printers.
Grids & Frames -> Unit grid (F7) shows a grid of the unit size chosen by the user (cf. Options -> Set unit. The name of the unit is displayed in the status bar.
Grids & Frames -> Fine grid (F8) shows two grids: of the unit size chosen by the user and of the accompanying unit. The names of the grid units are displayed in the status bar.
Grids & Frames -> Window grid shows a grid dividing both dimensions of the screen in ten equal parts. These are the units of the step for moving the screen frame.
Grids & Frames -> Clear grids (Ctrl+F7) clears all currently displayed grids.
