|
||
This widget is used to enter pixel distances/sizes and resolutions.
|
||
</p><p>
|
||
You can specify the number of fields the widget should provide. For
|
||
each field automatic mappings are performed between the field's
|
||
"reference value" and it's "value".
|
||
</p><p>
|
||
There is a <a href="GimpUnitMenu.html" title="GimpUnitMenu"><span class="type">GimpUnitMenu</span></a> right of the entry fields which lets you
|
||
specify the <a
|
||
href="../libgimpbase/libgimpbase-gimpunit.html#GimpUnit"
|
||
><span class="type">GimpUnit</span></a> of the displayed values.
|
||
</p><p>
|
||
For each field, there can be one or two <span class="type">GtkSpinButton</span>'s to enter
|
||
"value" and "reference value". If you specify <i class="parameter"><tt>show_refval</tt></i> as <span class="type">FALSE</span>
|
||
in <a href="GimpSizeEntry.html#gimp-size-entry-new"><tt class="function">gimp_size_entry_new()</tt></a> there will be only one <span class="type">GtkSpinButton</span> and the
|
||
<a href="GimpUnitMenu.html" title="GimpUnitMenu"><span class="type">GimpUnitMenu</span></a> will contain an item for selecting GIMP_UNIT_PIXEL.
|
||
</p><p>
|
||
The "reference value" is either of GIMP_UNIT_PIXEL or dpi, depending
|
||
on which <a href="GimpSizeEntry.html#GimpSizeEntryUpdatePolicy"><span class="type">GimpSizeEntryUpdatePolicy</span></a> you specify in <a href="GimpSizeEntry.html#gimp-size-entry-new"><tt class="function">gimp_size_entry_new()</tt></a>.
|
||
The "value" is either the size in pixels mapped to the size in a
|
||
real-world-unit (see <a
|
||
href="../libgimpbase/libgimpbase-gimpunit.html#GimpUnit"
|
||
><span class="type">GimpUnit</span></a>) or the dpi value mapped to pixels per
|
||
real-world-unit.
