<pre class="programlisting">#define GIMP_MAX_IMAGE_SIZE  262144    /*  2^18  */
</pre>
<p>
The maximum width and height of a GIMP image in pixels. This is a
somewhat arbitray value that can be used when an upper value for pixel
sizes is needed; for example to give a spin button an upper limit.

<pre class="programlisting">#define GIMP_MIN_RESOLUTION  5e-3      /*  shouldn't display as 0.000  */
</pre>
<p>
The minimum resolution of a GIMP image in pixels per inch. This is a
somewhat arbitray value that can be used to when a lower value for a
resolution is needed. GIMP will not accept resolutions smaller than
this value.

The maximum resolution of a GIMP image in pixels per inch. This is a

<p>
A large but arbitrary value that can be used when an upper limit for a
memory size (in bytes) is needed. It is smaller than <code class="literal">G_MAXDOUBLE</code> since
the <span class="type">GimpMemsizeEntry</span> doesn't handle larger values.
