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! |
