-This is the README file for the Raster display driver for lcd4linux
-
-This driver is intended to create various raster formats, at the moment 
-there is support for binary PPM (portable pixmap) and PNG.
-
-The driver creates the output file(s) specified with the -o switch. The
-parameter is used as a format string for sprintf(), if you specify '%d'
-in the output file, files with a sequence number will be created.
-
-The output file is first created with a '.tmp' extension, this temporary
-file will be written and closed, and finally (atomically) renamed. This way
-you can be shure that you will always get a complete file, but its contents
-changes every 'tick' milliseconds. 
-
-Configuration:
-
-The driver needs/supports the following entries in lcd4linux.conf:
-
-Display: must be either "PPM" or "PNG"
-size: [columns]x[rows], e.g. "20x4"
-font: [xrex]x[yres], at the moment only "5x8" and "6x8" supported.
-pixel: [pixelsize]+[pixelgap], e.g. "5+1"
-gap: [row gap]x[column gap], e.g. "3x3"
-border: border width
-foreground: color of an active LCD Pixel, must be #rrggbb
-halfground: color of an inactive LCD Pixel, must be #rrggbb
-background: backlight color, must be #rrggbb
-
-This may look weird, but it is weird. Let's explain this a bit further:
-The raster driver tries to emulate a real LC display. A real LCD has a
-size of columns*rows characters. Each character consists of xres*yres 
-LCD cells. One single cell will be represented by a rectangle of
-pixelsize*pixelsize pixels. If you want to, you can emulate the gap 
-between this lcd cells by specifying a pixelgap greater than zero.
-Sometimes there's a gap between characters, too. You can specify this 
-gap (in pixels again) horizontally and vertically. Usually this gap
-is the same size as a cell (which is pixelsize+pixelgap). If you specify
-either the row gap or the column gap as -1, this cell size will be used
-instead.
-
-If you use a font of 5x8, some characters may use the first and the last 
-pixel. So you should specify a column gap, otherwise the caracters may 
-touch. On the other hand, the 6x8 font never uses the first pixel. So you 
-can omit the column gap, and will get the same text layout, but 
-uninterupted bars!
-
-After all: don't try to understand this unless you have tried it out!
