Image Options
This section describes the options presented under the Image Tab of the preferences dialog.
Zoom
- Use nearest-neighbor sampling above 200% zoom
-
Displays crisp pixel boundaries above 200% magnification. At 200% and below, the selected zoom quality is used. Disabled by default. A keyboard shortcut can be assigned to this option in Preferences → Keyboard.
- Allow panning beyond image edges
-
Allows panning until any image edge or corner reaches the center of the viewing area. This makes it easier to inspect image boundaries. Disabled by default.
- Quality
-
Selects the method used to scale the size of an image:
- Nearest
-
Fastest scaler, but results in poor image quality.
- Tiles
-
Results are somewhat close to bilinear, with better speed.
- Bilinear
-
High quality results, moderately fast.
- Two pass rendering (apply HQ zoom and color correction in second pass)
-
Enables Geeqie to first display a scaled image using the Nearest zoom quality. After image decoding is complete, the image is scaled again using the selected Zoom Quality method, and ICC color correction is applied if color management is enabled. This allows faster display of an image as it is decoded from the source file, but the first pass is not color corrected and the colors may visibly change during the second pass.
Disable this option to apply the selected zoom quality and ICC color correction in a single rendering pass. This avoids displaying an uncorrected first pass, but may delay the initial display. Image preloading caches decoded source pixels; it does not pre-render them for the display's color profile.
- Zoom increment
-
Adjusts the step size when zooming in or out on an image.
- Zoom style
-
Selects whether the zoom step size is applied as a geometric (n * step) or arithmetic (n + step) factor.
Fit Image To Window
- Allow enlargement of image (max. size in %)
-
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 Fit image to window . This value sets the maximum expansion permitted in percent i.e. 100% is full-size.
- Virtual window size (% of actual window)
-
This value will set the virtual size of the window when Fit image to window 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.
Tile Size
- Tile size in pixels
-
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.
Appearance
- Custom border color
-
Enable this to draw the image background (the area around the image) in the specified color.
- Border color
-
Use this color chooser to define the color to use as image background.
You may use the Virtual window size (see above) option to keep a border around the image in fullscreen mode.
- Alpha channel color 1/2
-
These two colors define the checkerboard background used when images with an alpha channel are displayed.
