APP/APG v2.0 Panorama Editor

Interface Overview

Panorama Editor Screen Capture

The Panorama Editor Window interface is divided into 6 main areas:

  • The Toolbar: offering a collection of the main tools (saving, history, geometrical correction, color correction, etc.)
  • The Preview area: displaying a preview of the panorama, allowing to zoom in and to move the panorama.
  • The Layers area: allow for images classification based on several parameters, also allow for deletion of unwanted images.
  • The Status Bar: displaying information related to shooting conditions. This information is useful to monitor the coherence of the capture. For example, for a complete panorama, the FOV should return a Theta Min/Max -180°/180° and a Phi Min/Max -90°/90°.
  • The History area: allowing to move backward and forward in the edition history and to take snapshots of the current editing stage.

The Preview Area

Zoom type in GPU mode

The Preview Area allows you to zoom in and out the panorama.

  • To move the panorama:
  1. Press and maintain the keyboard spacebar down then left click on the panorama and move it around while keeping the left mouse button down.
  • To zoom:
  1. Press and maintain the keyboard Alt key down (or Apple key on a Mac) then use the mouse scroll wheel to zoom in and out.
  2. Or use the graphical tools located right under the panorama preview.


  • Some tools are using the keyboard and/or the mouse, like the Layer View mode.
  • It is also possible to adjust the panorama preview size to the window size by selecting the "Fit Pano on Screen" zoom setting or uing the Ctrl+0 keyboard shortcut..

You can play with the various types of zoom provided to determine which one fits best into your workflow.

The Toolbar


Project Files

The Autopano Pro project file (.pano extension) is a file used to save all the panorama parameters: the list of source images used, the color correction parameters, the rendering file format, etc. It can be useful to keep this file in order to come back to a panorama at a later time and render it again without having to go through the detection process again. This file is a plain text file and can be opened with any text editor.

Autopano Pro also supports other very popular project file types: the PanoTools project file formats. You can also import from and export to those file formats.

Pano save.png Save

Saves the project with its current name. Combine with CTRL keyboard key: the button will then behave as a "Save as …" button .

Pano save.png Save As ...

Saves the project while specifying the saving location and the name it should be saved as.

Pano save.png Extended Save As ...

Extended Save As...

Saves the project while specifying the saving location and the name it should be saved as. On top of that you can copy or move your source images to a target directory defined using the syntax entered in the Path input box. This allow for a per project image archival in a very simple way.

The path is based on a special and highly efficient syntax model allowing for example to specify the project directory name as well as the name of the project itself.

%p Project directory
%a Project name

The default syntax model is as follow: "%p/%a translating in the following example:
C:\..\Desktop\[Group 1]-SNB11285-3 images
%p = C:\..\Desktop
%a = [Group 1]-SNB11285-3 images

Pano save.png Save As Template ...

Save As Template ...

This option will allow you to save the detected image links for this project. It will then be possible to use the same links as a template for a similar stitching. The link pattern to be used can be chosen in the Detection option (Free, Single Row or Column, List all Models…).

Pano export.png Export to Panotools

Using this option will export the Autopano project into a format usable by the PanoTools suite of tools: Autopano can read and write the following project file formats: PTGui (.pts file format), PTAssembler (.ptp file format) and Hugin (.pto file format).



You need to undo the last few actions performed on your panorama as you are not satisfied with the result? No problem! Just click on the "History" button. The "History" dialog will pop up and display a list of all the steps performed since the panorama was created or opened. All you need to do is click on the desired step to restart from there.

The dialog will also allow you to take a snapshot of the panorama at any given time. Just click on the "Take a snapshot" button in the History dialog. You will then be able to restore the snapshot state by clicking on the desired Snapshot Thumbnail.

Keep in mind that exiting the Panorama Editor will discard the History information. If you reopen the same panorama, only its last version will be displayed in the History.

Icon-tips-24.png Tip:

  • You can take a snapshot every time you save your work to keep track of your progression.
  • You can also use this snapshot feature to compare two different color levels settings for example.

Editor Settings

Editor Tab

Editor Settings

  • Preview quality (CPU mode only)

This set of parameters only influences the quality of the preview and the way the editor works. The parameters influencing the quality of the final image are set in the Launch Render dialog or in the Render tab of the Application Settings dialog.

    • Size: here you can set the panorama preview size (in pixels) inside the panorama editor window (refreshed after each adjustment of an editing parameter).
      The default display size is 1200 x 600, the highest quality setting being 3200 x 1600. Since any alteration of this setting is taken into account in real time and because it can be modified through the Edit menu of the editor window, the best thing to do is to reduce the quality when the preview’s refresh time is becoming too long and to increase the quality when individual pixels become too visible (the interpolation and the blender also affect the panorama editor preview refresh time). Increase the preview quality if you need to zoom into the image otherwise just leave the default value on.
    • Interpolation: let you determine how the pixel values of the preview are computed from the source images pixels.
    • Blending: let you choose how the images are blended together in the overlapping zones. Several blenders are available inside Autopano but only some of them are available for the preview:
      • None: no blending, the "top image" is visible.
      • Linear: this mode is fast and generates good quality results.
      • Multiband: slower but better quality.
  • Grid
    • This set of options is used to define the grid’s properties, such as the type of lines used and their spacing.
  • Toolbar

This setting will alter the visual aspect of the editor’s toolbar.

    • Icon size: changes the size of the toolbar icons.
    • Style: changes the style of the toolbar buttons.

The Toolbar Section

This set of options controls the size of the icons displayed in the Panorama editor’s toolbar. You can also choose to display some descriptive text beside, and under the icon, or choose to have only text displayed and hide the icons.
