|
.SH SYNOPSIS
|
|
.B spred
|
|
.SH DESCRIPTION
|
|
.I Spred
|
|
is an editor for small images using a limited palette.
|
|
It uses a window system mimicking
|
|
.IR sam (1).
|
|
There is a command window which uses a command language described below.
|
|
There is also an arbitrary number of palette and sprite windows.
|
|
Each open sprite file has an associated palette file.
|
|
.PP
|
|
A left click on a color in a palette window selects that color.
|
|
Colors in different palettes can be selected indepedently.
|
|
A left click on a pixel in a sprite window sets that pixel to the selected color.
|
|
.PP
|
|
A right click brings up the global menu to create windows etc.
|
|
It also lists all currently open files, including those that are not open in any window.
|
|
A middle click brings up the menu for the local window, if applicable. Available commands there are:
|
|
.TP
|
|
.I pal
|
|
The \fIpal\fR command sets the palette for the current sprite window. The palette is selected with a middle click.
|
|
.PP
|
|
The command language is a very stripped down version of
|
|
.IR rc (1),
|
|
currently only supporting "simple" commands consisting of a name and an arbitrary number of arguments separated by spaces. Quoting works just like with
|
|
.IR rc (1).
|
|
Available commands are:
|
|
.TP
|
|
.B q
|
|
Quits the program. If any files have unsaved changes, it will fail on the first attempt to quit.
|
|
.TP
|
|
.BI pal " file
|
|
.TP
|
|
.BI spr " file

|
|
.TP
|
|
.BI w " file
|
|

|
|
.TP
|
|
.BI size " sz
|
|
Sets the size of the current file to \fIsz\fR.
|
|
\fISz\fR should be of the form \fIn\fR for palettes or \fIn\fB*\fIm\fR for sprites where \fIn\fR and \fIm\fR are integers.
|
|
.TP
|
|
.B set 0x\fIrrggbb\fR
|
|

|
|
\fIrr, gg\fR and \fIbb\fR are in hexadecimal notation.
