<a href='im_csv2vips.3.html'><b>im_csv2vips(3)</a>
</b> reads the CSV (comma separated values) data in filename, and writes the
image out in VIPS format. The output image is always 1 band (monochrome),
IM_BANDFMT_DOUBLE.
<p> The reader is deliberately rather fussy: it will fail
if there are any short lines, or if the file is too short. It will ignore
lines that are too long.
<p> Read options can be embedded in the filename. The
options can be given in any order and are:
<p> skip:lines-to-skip<br>
<p> The number of lines to skip at the start of the file. Default zero.
<p>
whi:whitespace-characters<br>
<p> The skippable whitespace characters. Default <space> and double quotes (").
Whitespace characters are always run together.
<p> sep:separator-characters<br>
<p> The characters that separate fields. Default ;,<tab>. Separators are never
run together.
<p> line:lines-to-read<br>
<p> The number of lines to read from the file. Default -1, meaning read to
end of file.
<p> <a href='im_vips2csv.3.html'><b>im_vips2csv(3)</b></a>
writes the VIPS image to the file as ascii
text, one line of text per scanline. Complex numbers are written as "(real,imaginary)"
and will need extra parsing I guess.
<p> Write options can be embedded in
the filename. The options can be given in any order and are:
<p> sep:separator-string<br>
<p> The string to use to separate numbers in the output. The default is "\t"
(tab).
<p>
<h2><a name='sect3' href='#toc3'>Examples</a></h2>
<p> im_csv2vips( "fred.csv:skip:58,sep:,,line:3", out );<br>
<p> Will read three lines starting at line 59, with space, comma and tab
as the allowed separators. Note that the ’,’ has to be escaped with a backslash.
<p> im_vips2csv fred.jpg fred.csv:sep:t<br>
<p> Convert a jpeg to CSV, separating numbers with tab characters.
