Declarations
png.occ
:31Process read.raster.png
PROC read.raster.png (VAL []BYTE filename, RESULT RASTER raster)
Load a PNG file as a raster.
png.occ
:43Process write.raster.png
PROC write.raster.png (VAL []BYTE filename, VAL [][]INT raster)
Write a raster out as a PNG file.
ppmwrite.occ
:27Process write.raster.ppm
PROC write.raster.ppm (VAL []BYTE filename, VAL [][]INT raster)
Write a raster out as a PPM file.
rasterio.occ
:37Process read.raster
PROC read.raster (VAL []BYTE filename, RESULT RASTER raster)
Load an image file as a raster, with the format determined automatically based on the extension.
The following extensions are currently supported:
-
.png
rasterio.occ
:55Process write.raster
PROC write.raster (VAL []BYTE filename, VAL [][]INT raster)
Write a raster to a file, with the format determined automatically based on the extension.
The following extensions are currently supported:
-
.png
-
.ppm
rasterio.occ
:79Process write.rasters
PROC write.rasters (VAL []BYTE prefix, suffix, CHAN RASTER in?, out!)
Write rasters to files.
As each raster passes through, it's written to a file named prefix000000suffix
, with the number incrementing by one for each frame. The files can be in any format supported by write.raster
.
You can convert the resulting files into a video using mencoder
or a similar tool; see the mencoder
manual for more details.
