View

The view displays the current file. You can pan, zoom, or frame the view so the image fills the available space.

Default view controls:

• Pan — Middle mouse button
• Zoom — Mouse wheel, or the - and = keys
• Frame view (fit image to view) — Backspace
• Wipe (in compare mode) — Alt + left mouse button
• Color picker — Ctrl + left mouse button
• Frame shuttle (scrub frames by dragging) — Left mouse button

View controls can be remapped in the Mouse section of the Settings tool.

Framing and zoom

The view can be framed (fit to the view), reset to 1:1, or zoomed in and out from the View menu and the zoom control on the View tool bar.

Options

• Minify — Filter used when the image is scaled down (Nearest or Linear).
• Magnify — Filter used when the image is scaled up. Use Nearest to see individual pixels without smoothing.
• Video levels — How video levels are interpreted: from the file, full range, or legal range.
• Alpha blend — How the alpha channel is blended: none, straight, or pre-multiplied.
• Color buffer — The view’s bit depth. The default, RGBA F32, is recommended because it preserves the full range of color values without clamping. Lower bit-depth options can be faster, but they can clamp colors — choose them only when performance is more important than precision.

Aspect ratio

The pixel aspect ratio can be left at the file’s default or overridden. Up to three custom aspect ratios can be defined.

Outline

An outline can be drawn around the image to make transparent regions easier to distinguish from the background.
