Image Size and Position
Four fit settings determine the initial image size. 100% Fit displays the image at its actual size (in pixels). Fit Width and Fit Height stretches the image to the full width or height of the window (stretch can also mean shrink in this context). Fit Window chooses whichever of the width or height methods that gives the largest image. In all cases, the image is centered in the window. The settings are chosen in the Fit submenus of the Image and image context menus. The current setting is checked unless the image size has been changed by zooming.Interactive zooming is accomplished by dragging out a rectangle while holding down the left mouse button and <shift> key. The image is resized when the mouse button is released. The rectangle bounds are used as the visible limits of the resized image. Unless the aspect ratio of the rectangle is the same as that of the window, more of the image will be shown than was enclosed in the rectangle.
The Zoom In
toolbar button enlarges the image by a factor 3/2. The Zoom Out
button reverses the operation. The center of the image remains fixed. The Last Zoom
button restores the previous scale state that was set by either a zoom operation or the application of a fit setting.
Vertical and horizontal scrollbars at the image window edge can be used to scroll hidden regions of an enlarged image into view. The scrollbars are present, but inactive, if the entire image is visible.
The image is mirrored in the vertical direction the Flip Vertical menu item or the corresponding toolbar button
