Vips.Image.csvsave

### Method

# Vips Imagecsvsave

#### Declaration [src]

    int
    vips_csvsave (
      VipsImage* in,
      const char* filename,
      ...
    )

#### Description [src]

Writes the pixels in `in` to the `filename` as CSV (comma-separated values).

The image is written one line of text per scanline. Complex numbers are written as “(real,imaginary)” and will need extra parsing I guess. Only the first band is written.

`separator` gives the string to use to separate numbers in the output. The default is “\t” (tab).

Optional arguments

- `separator`: `gchararray`, separator string
