<span id="index-plotting_002c-saving-and-printing-plots"></span>
<span id="index-printing-plots"></span>
<span id="index-saving-plots"></span>
<p>The <code>print</code> command allows you to send plots to you printer and
to save plots in a variety of formats. For example,
</p>
<div class="example">
<pre class="example">print -dpsc
</pre></div>
<p>prints the current figure to a color PostScript printer. And,
</p>
<div class="example">
<pre class="example">print -deps foo.eps
</pre></div>
<p>saves the current figure to an encapsulated PostScript file called
<samp>foo.eps</samp>.
</p>
<p>The current graphic toolkits produce very similar graphic displays, but differ
in their capability to display unusual text and in their ability to print
such text. In general, the <code>"tex"</code> interpreter (default) is the best
all-around performer for both on-screen display and printing. However, for the
reproduction of complicated text formulas the <code>"latex"</code> interpreter is
preferred. The <code>"latex"</code> interpreter will not display symbols on-screen,
but the printed output will be correct. When printing, use one of the
<code>standalone</code> options which provide full access to LaTeX commands.
</p>
<p>A complete example showing the capabilities of text printing using the
<samp>-dpdflatexstandalone</samp> option is:
</p>
<div class="example">
<pre class="example">x = 0:0.01:3;
hf = figure ();
plot (x, erf (x));
hold on;
plot (x, x, "r");
axis ([0, 3, 0, 1]);
text (0.65, 0.6175, ...
['$\displaystyle\leftarrow x = {2 \over \sqrt{\pi}}' ...
'\int_{0}^{x} e^{-t^2} dt = 0.6175$'],
"interpreter", "latex");
xlabel ("x");
ylabel ("erf (x)");
title ("erf (x) with text annotation");
print (hf, "plot15_7", "-dpdflatexstandalone");
system ("pdflatex plot15_7");
open plot15_7.pdf
</pre></div>
<p>The result of this example can be seen in <a href="#fig_003aextendedtext">Figure 15.7</a>
</p>
<div class="float"><span id="fig_003aextendedtext"></span>
<div align="center"><img src="extended.png" alt="extended">
</div>
<div class="float-caption"><p><strong>Figure 15.7: </strong>Example of inclusion of text with use of <samp>-dpdflatexstandalone</samp></p></div></div>
<span id="XREFprint"></span><dl>
<dt id="index-print">: <em></em> <strong>print</strong> <em>()</em></dt>
<dt id="index-print-1">: <em></em> <strong>print</strong> <em>(<var>options</var>)</em></dt>
<dt id="index-print-2">: <em></em> <strong>print</strong> <em>(<var>filename</var>, <var>options</var>)</em></dt>
<dt id="index-print-3">: <em></em> <strong>print</strong> <em>(<var>hfig</var>, …)</em></dt>
<dt id="index-print-4">: <em><var>rgb</var> =</em> <strong>print</strong> <em>(<code>"-RGBImage"</code>, …)</em></dt>
<dd><p>Format a figure for printing and either save it to a file, send it to a
printer, or return an RGB image.
</p>
<p><var>filename</var> defines the name of the output file. If the filename has
no suffix then one is inferred from the specified device and appended to the
filename. When neither a filename nor the <code>"-RGBImage"</code> option is
present, the output is sent to the printer. The various options and
filename arguments may be given in any order, except for the figure handle
argument <var>hfig</var> which must be first if it is present.
</p>
<p>Example: Print to a file using PDF and JPEG formats.
</p>
<div class="example">
<pre class="example">figure (1);
clf ();
surf (peaks);
print figure1.pdf # The extension specifies the format
print -djpg figure1 # Will produce "figure1.jpg" file
</pre></div>
<p>If the first argument is a handle <var>hfig</var> to a figure object then it
specifies the figure to print. By default, the current figure returned
by <code>gcf</code> is printed.
</p>
<p>For outputs to paged formats, for example, PostScript and PDF, the page size
is specified by the figure’s <code>papersize</code> property together with the
<code>paperunits</code> property. The location and size of the plot on the page
are specified by the figure’s <code>paperposition</code> property. The
orientation of the page is specified by the figure’s <code>paperorientation</code>
property.
</p>
<p>For non-page formats—for example, image formats like JPEG—the width and
height of the output are specified by the figure’s <code>paperposition(3:4)</code>
property values.
</p>
<p>The <code>print</code> command supports many <var>options</var>:
</p>
<dl compact="compact">
<dt><code>-f<var>h</var></code></dt>
<dd><p>Specify the handle, <var>h</var>, of the figure to be printed.
</p>
<p>Example: Print figure 1.
</p>
<div class="example">
<pre class="example">figure (1);
clf ();
surf (peaks);
figure (2);
print -f1 figure1.pdf
## Equivalent functional form:
print (1, "figure1.pdf")
</pre></div>
</dd>
<dt><code>-P<var>printer</var></code></dt>
<dd><p>Set the <var>printer</var> name to which the plot is sent if no <var>filename</var>
is specified.
</p>
<p>Example: Print to printer named PS_printer using PostScript format.
</p>
<div class="example">
<pre class="example">clf ();
surf (peaks);
print -dpswrite -PPS_printer
</pre></div>
</dd>
<dt><code>-RGBImage</code></dt>
<dd><p>Return an M-by-N-by-3 RGB image of the figure. The size of the image
depends on the formatting options. This is similar to taking a screen
capture of the plot, but formatting options may be changed such as the
resolution or monochrome/color.
</p>
<p>Example: Get the pixels of a figure image.
</p>
<div class="example">
<pre class="example">clf ();
surf (peaks);
<var>rgb</var> = print ("-RGBImage");
</pre></div>
</dd>
<dt><code>-opengl</code></dt>
<dt><code>-painters</code></dt>
<dd><p>Specifies whether the opengl (pixel-based) or painters (vector-based)
renderer is used. This is equivalent to changing the figure’s
<code>"Renderer"</code> property. When the figure <code>"RendererMode"</code>
property is <code>"auto"</code> (the default) Octave will use the
<code>"opengl"</code> renderer for raster formats (e.g., JPEG) and
<code>"painters"</code> for vector formats (e.g., PDF). Those options are only
supported for the "qt" graphics toolkit.
</p>
</dd>
<dt><code>-svgconvert</code></dt>
<dd><p>When using the <samp>-painters</samp> renderer, this enables a different
backend toolchain with enhanced characteristics:
</p>
<dl compact="compact">
<dt>Font handling:</dt>
<dd><p>The actual font is embedded in the output file which allows for printing
arbitrary characters and fonts in all vector formats.
</p>
</dd>
<dt>Output Simplification:</dt>
<dd><p>By default, the option <samp>-painters</samp> renders patch and surface objects
using assemblies of triangles. This may lead to anti-aliasing artifacts
when viewing the file. The <samp>-svgconvert</samp> option reconstructs
polygons in order to avoid those artifacts (particularly for 2-D figures).
</p>
</dd>
<dt>Transparency:</dt>
<dd><p>Allows for printing transparent graphics objects in PDF format.
For PostScript formats the presence of any transparent object will cause the
output to be rasterized.
</p></dd>
</dl>
<p>Caution: <samp>-svgconvert</samp> may lead to inaccurate rendering of image
objects.
</p>
</dd>
<dt><code>-portrait</code></dt>
<dt><code>-landscape</code></dt>
<dd><p>Specify the orientation of the plot for printed output.
For non-printed output the aspect ratio of the output corresponds to the
plot area defined by the <code>"paperposition"</code> property in the
orientation specified. This option is equivalent to changing the figure’s
<code>"paperorientation"</code> property.
</p>
</dd>
<dt><code>-fillpage</code></dt>
<dt><code>-bestfit</code></dt>
<dd><p>When using a page-based format (PDF, PostScript, printer) ignore the
<code>"paperposition"</code> property and have the plot occupy the entire page.
The option <samp>-fillpage</samp> will stretch the plot to occupy the page with
0.25 inch margins all around. The option <samp>-bestfit</samp> will expand the
plot to take up as much room as possible on the page <strong>without</strong>
distorting the original aspect ratio of the plot.
</p>
</dd>
<dt><code>-color</code></dt>
<dt><code>-mono</code></dt>
<dd><p>Color or monochrome output.
</p>
</dd>
<dt><code>-solid</code></dt>
<dt><code>-dashed</code></dt>
<dd><p>Force all lines to be solid or dashed, respectively.
</p>
</dd>
<dt><code>-noui</code></dt>
<dd><p>Don’t print uicontrol objects such as pushbuttons which may overlay the
plot. This is the default behavior and it is not possible to include
uicontrol objects in the output without using an external screen capture
tool.
</p>
</dd>
<dt><code>-r<var>NUM</var></code></dt>
<dd><p>Resolution of bitmaps in dots per inch (DPI). For both metafiles and SVG
the default is the screen resolution; for other formats the default is 150
DPI. To specify screen resolution, use <code>"-r0"</code>.
</p>
<p>Example: high resolution raster output.
</p>
<div class="example">
<pre class="example">clf ();
surf (peaks (), "facelighting", "gouraud");
light ();
print ("-r600", "lit_peaks.png");

<p><code>print</code> and <code>saveas</code> are used when work on a plot has finished
and the output must be in a publication-ready format. During intermediate
stages it is often better to save the graphics object and all of its
associated information so that changes—to colors, axis limits, marker styles,
etc.—can be made easily from within Octave. The <code>hgsave</code>/<code>hgload</code>
commands can be used to save and re-create a graphics object.

<p>When <var>filename</var> does not have an extension the default filename

<p>The default format is <samp>-binary</samp> to minimize storage.

<p>Programming Note: When producing graphics for final publication use
<code>print</code> or <code>saveas</code>. When it is important to be able to continue
to edit a figure as an Octave object, use <code>hgsave</code>/<code>hgload</code>.
