4 <para>This section describes the options presented under the Image Tab of the preferences dialog.</para>
\r
10 <guilabel>Quality</guilabel>
\r
14 Selects the method used to scale the size of an image:
\r
18 <guilabel>Nearest</guilabel>
\r
21 <para>Fastest scaler, but results in poor image quality.</para>
\r
26 <guilabel>Tiles</guilabel>
\r
29 <para>Results are somewhat close to bilinear, with better speed.</para>
\r
34 <guilabel>Bilinear</guilabel>
\r
37 <para>High quality results, moderately fast.</para>
\r
46 <guilabel>Use GPU acceleration via Clutter library</guilabel>
\r
49 <para>Use alternate renderer. Geeqie must be compiled with the --enable-gpu-accel option.</para>
\r
54 <guilabel>Two pass zooming</guilabel>
\r
58 Enables Geeqie to first display a scaled image using the
\r
59 <emphasis>Nearest</emphasis>
\r
60 zoom quality. After image decoding is complete, the image is scaled again using the selected
\r
61 <emphasis>Zoom Quality</emphasis>
\r
62 method. This allows faster display of an image as it is decoded from the source file.
\r
68 <guilabel>Zoom increment</guilabel>
\r
71 <para>Adjusts the step size when zooming in or out on an image.</para>
\r
76 <guilabel>Zoom style</guilabel>
\r
79 <para>Selects whether the zoom step size is applied as a geometric (n * step) or arithmetic (n + step) factor.</para>
\r
84 <section id="FitImageToWindow">
\r
85 <title>Fit Image To Window</title>
\r
89 <guilabel>Allow enlargement of image (max. size in %)</guilabel>
\r
93 Enable this to allow Geeqie to increase the image size for images that are smaller than the current view area when the zoom is set to
\r
94 <emphasis>Fit image to window</emphasis>
\r
95 . This value sets the maximum expansion permitted in percent i.e. 100% is full-size.
\r
101 <guilabel>Virtual window size (% of actual window)</guilabel>
\r
105 This value will set the virtual size of the window when
\r
106 <emphasis>Fit image to window</emphasis>
\r
107 is set. Instead of using the actual size of the window, the specified percentage of the window will be used. It allows one to keep a border around the image (values lower than 100%) or to auto zoom the image (values greater than 100%). It affects fullscreen mode too.
\r
113 <section id="TileSize">
\r
114 <title>Tile Size</title>
\r
118 <guilabel>Tile size in pixels</guilabel>
\r
122 This option is only available when GPU acceleration is not selected. It sets the size in pixels that large images are split into during rendering. Setting a larger value will reduce the tiling effect seen as the image is displayed, but will also slightly increase the delay until the first part of the image is seen.

128 <section id="Appearance">

129 <title>Appearance</title>
\r
133 <guilabel>Custom border color</guilabel>
\r
136 <para>Enable this to draw the image background (the area around the image) in the specified color.</para>
\r
143 <guilabel>Border color</guilabel>
\r
146 <para>Use this color chooser to define the color to use as image background.</para>
\r
150 <emphasis>Virtual window size</emphasis>
\r
151 (see above) option to keep a border around the image in fullscreen mode.
\r
160 <guilabel>Alpha channel color 1/2</guilabel>
\r
163 <para>These two colors define the checkerboard background used when images with an alpha channel are displayed.</para>
