4 <para>This section describes the options presented under the Image Tab of the preferences dialog.</para>
10 <guilabel>Quality</guilabel>
14 Selects the method used to scale the size of an image:
18 <guilabel>Nearest</guilabel>
21 <para>Fastest scaler, but results in poor image quality.</para>
26 <guilabel>Tiles</guilabel>
29 <para>Results are somewhat close to bilinear, with better speed.</para>
34 <guilabel>Bilinear</guilabel>
37 <para>High quality results, moderately fast.</para>
46 <guilabel>Two pass zooming</guilabel>
50 Enables Geeqie to first display a scaled image using the
51 <emphasis>Nearest</emphasis>
52 zoom quality. After image decoding is complete, the image is scaled again using the selected
53 <emphasis>Zoom Quality</emphasis>
54 method. This allows faster display of an image as it is decoded from the source file.
60 <guilabel>Zoom increment</guilabel>
63 <para>Adjusts the step size when zooming in or out on an image.</para>
68 <guilabel>Zoom style</guilabel>
71 <para>Selects whether the zoom step size is applied as a geometric (n * step) or arithmetic (n + step) factor.</para>
76 <section id="FitImageToWindow">
77 <title>Fit Image To Window</title>
81 <guilabel>Allow enlargement of image (max. size in %)</guilabel>
85 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
86 <emphasis>Fit image to window</emphasis>
87 . This value sets the maximum expansion permitted in percent i.e. 100% is full-size.
93 <guilabel>Virtual window size (% of actual window)</guilabel>
97 This value will set the virtual size of the window when
98 <emphasis>Fit image to window</emphasis>
99 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.
105 <section id="TileSize">
106 <title>Tile Size</title>
110 <guilabel>Tile size in pixels</guilabel>
114 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.
120 <section id="Appearance">
121 <title>Appearance</title>
125 <guilabel>Custom border color</guilabel>
128 <para>Enable this to draw the image background (the area around the image) in the specified color.</para>
135 <guilabel>Border color</guilabel>
138 <para>Use this color chooser to define the color to use as image background.</para>
142 <emphasis>Virtual window size</emphasis>
143 (see above) option to keep a border around the image in fullscreen mode.
152 <guilabel>Alpha channel color 1/2</guilabel>
155 <para>These two colors define the checkerboard background used when images with an alpha channel are displayed.</para>
