Arguments

file

A filename of an IFF file to be read, or a connection from which binary data can be read.

Details

Information is stored as `chunks' in IFF files (see IFFChunk). Each chunk should at least contain a label of the type of chunk and the data for that chunk. This function reads all chunks from a valid IFF file, including all nested chunks and stores them in an IFFChunk object. IFF files can hold any kind of data (e.g. images or audio), this read function does not interpret the file. Use interpretIFFChunk for that purpose.

Examples

if (FALSE) {
## let's read a bitmap image stored in IFF as provided with this package:
filename <- system.file("ilbm8lores.iff", package = "AmigaFFH")
example.iff <- read.iff(filename)

## And plot it:
plot(example.iff)
}
