-This is the README file for the Png display driver for lcd4linux.
-
-Preliminarys: libgd, libpng, libz
-Optional: perl, apache
-
-The driver creates the output file 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 "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
-
-For details please look into README.Raster.
-
-To display this png file continuosly in a web page, follow these instructions:
-Copy the sample png.html to an appropriate place under your htdocs.
-Copy the sample nph-png perl script into your cgi-bin directory, and adjust
-png.html to contain this directory.
-Adjust nph-png to contain the path/filename of the outputfile (s -o above).
-Start lcd4linux -o path/filename.png.
-If you are on a slow connection to your webserver you might also adjust the
-$DELAY in nph-png or in lcd4linux.conf.
-
-Note: depending on your webervers configuration, you must rename nph-png to
- nph-png.pl or npg-png.cgi.
-
-Have fun.
