If folders are selected in the dialog "Slide Show…" from the File menu, Pix starts a slide show displaying all images in these "root folders", ordered lexicographically, randomly, or by creation date—which order is applied is determined by Pix's preferences.
Iff the "folderwise" checkbox in the preferences is checked, then the set of all image files is partitioned into groups, where two files belong to the same group iff they have the same direct containing folder. The files of a group are then displayed contiguously. Exception: If the folder name does not end with an asterisk (*), then at most one video in this folder is put into the group, the others are treated as if they were contained in individual single-element folders.
If "folderwise" and "chronological" are chosen, then the files of the folder are shown in chronological order, but the order of the folders is random.
If the root folders do not contain any image file, an error message is displayed.
When the slide show is running, it can be suspended and resumed by giving the command Toggle in the Slide Show menu. If the slide show window shows a still picture (rather than a video clip), then hitting the space bar on the keyboard does the same. (If a video clip is displayed, then the space bar controls suspension and resumption of the video playback.) If and only if the slide show is suspended, then the title of the window has a trailing 🛑 symbol.
With the menu command Add Folders… the running slide show can be extended to cover more folders. This causes a rescan of all folders used for the slide show.
The Advance and Step Back commands in the Slide Show menu let the slide show jump to the next resp. previous picture. If the slide show window shows a still picture (rather than a video clip), then the '<' and left arrow keys let the slide show jump to the previous picture, most of the other keys tell it to advance.
The images shown in the slide show can also be rotated and regions can be selected and magnified, as described in chapter Single Image View.
You can set the current position of the slide show to an arbitrary element of the slide show collection by using the menu item Go to File…, and to a random one with Go to Random File.
With the menu item Move to Next Screen you can move the slide show window around if you have multiple screens.
The Delete menu command works similar to the full image window, but rather than closing the window, the slide show is advanced to the image following the deleted one. It is enabled only when the slide is suspended, in order to prevent inadvertent deletion of a wrong file.
Using the menu item Skip Marked images you can advise Pix to skip marked pictures, such that those pictures are not shown in the slide show. Use the same menu item to switch off this behavior. The slide show window has a small red square in its upper right corner iff skipping is switched on. For how to mark/unmark images see the Image View page.
In the upper left corner of the window you see the position of the curent image in the slide show, the total number of images, and the creation date of the current file. After the file list has been built, the text color changes randomly. Before that, i.e. while the file list is being built, the text is white.
