SPL format

Top Previous Next

Beside the issue of the plot data on a plotter integrated in the operating system or printer the data can be given in the SPL format. SPL controls only few commands: Pen up, Pen down, colour choice, position start.

A SPL file has the construction:

M37<CR>

M0<CR>

SPL files are pure text files without tax sign.

Several commands can stand in a line. No separators are arranged between the commands. Every command begins with a letter, a number follows as a parametre. All commands are stored and <>released at the end of the line, so by the <CR>.

Komandos

D<gerade number from 10>

With this line a new pencil is chosen. there are no pencil widths. With D10 becomes the first pencil, with D12 second stift elective, etc. this command seems to have to stand alone in a line.

X<zahl >

A new X position is given. The value has 1/100 mm as a unity. The left corner is 0. However, the pencil remains in the present position, until a <CR> has appeared.

Y<zahl>

A new Y position is given. The value has 1/100 mm as a unity. The lower edge has the value 0. However, the pencil remains in the present position, until a <CR> has appeared.

D1	The pencil is lowered.

D2	The pencil is raised

<CR>	With X and Y given position is started. Before the pencil is served according to the D2-Komando.
