Papywizard User Guide (subversion)
This documentation refers to the stable release 1.2.
For installation instructions, see here.
Papywizard is very easy to use, and I hope the GUI is intuitive enough.
The first thing to do is to edit the configuration, to reflect you camera/lens/head/hardware config. Basic settings are the delay to wait after moving (to let the head stop shaking), the delay to wait while shooting (camera Tv value), and the number of pictures to take at each position (bracketing). See below for specific mode settings.
Second, you need to connect to the hardware (Menu Hardware > Connect). If you use the bluetooth driver (default config), you need to enter the correct address of your adapter. Alternatively, you can get a list of all available bluetooth devices arround, and select the correct one.
Then, just move the head either using the big GUI arrows, or using the keys shortcuts (see below), and set the start/end positions.
Once it is done, just open the shooting dialog and launch the entire process. That's it!
Papywizard has now 2 modes: Mosaic mode, and Preset mode. The first one is mainly used for partial panos, and is especially designed for hi-res panos, using a large tele-lens. The second one is designed for full-spherical panos, using a wide-lens or a fisheye.
The mosaic mode computations are based on the following parameters:
- minimum overlap
- camera orientation
- sensor coef. and ratio
- focal lens
So, these settings must exactly reflect your configuration.
It also needs the start/end positions, which are two opposite corners of the pano you want to shoot. It does not matter which corner you use for start or end, but it will influence the direction the pano will be shot. Note that, depending of the settings, Papywizard can start shooting from the start position, or from the end position. This is usefull to avoid the head to go back to the opposite corner before shooting (which takes time and uses batteries).
It is also possible to choose the initial shooting direction. Using yaw will shoot row by row; using pitch will shoot column by column. Same, the head can go back to the begining of the row/column before shooting the next one (see Tips and tricks).
This mode is very simple, and does not use any particular settings; it just shoots at all positions defined in the selected template. The only thing to do is to define the home position of the head (origin), which will be the reference for the template positions (see Tips and tricks). In case the camera/lens can't be moved in all positions, it is possible to set some limits, to avoid potential colisions (limits are not saved in the current release, so they must be set each time the head is turned on).
Some default presets are provided with the software, but it is possible to add your own. For that, you need to create a xml file which describes them. The file must be named presets.xml and must be in ~/.config/papywizard/ on linux, /home/user/.config/papywizard/ on maemo, and C:\Documents and settings\<user>\Application Data\papywizard\ on Windows.
Here is the file structure:
<?xml version="1.0" encoding="utf-8" ?> <papywizard> <preset name="My custom preset"> <tooltip> 20D + 50mm 12 picts @ +55° 20 picts @ +40° 50 picts @ 10°/-10° 20 picts @ -40° 55 picts @ -70° </tooltip> <shoot> <pict yaw="0." pitch="55." /> <pict yaw="30." pitch="55." /> <pict yaw="60." pitch="55." /> <pict yaw="90." pitch="55." /> ... </shoot> </preset> <preset name="Another custom preset"> .... </preset> </papywizard>
- <preset> name attribute: name used to present the preset in the GUI
- <tooltip>: information for that preset (shown in the information presets template window)
- <shoot>: list of all positions to shoot, described in yaw/pitch attributes of the <pict> tag (one tag per position)
To save time during shoot, take care of the order of positions. For example, don't ask the head to go back to the begining of the new row, it will take too long; instead, reverse the direction and go back for the next row.
You can also import a custom preset file from the File menu. Note that this file won't be automatically loaded at next startup; this is mainly to test your presets before putting them in your user config. dir.
If you add usefull templates, feel free to send them so they could be added as default ones.
As all files managed by Papywizard are xml, it is very easy to convert an output data file to a presets.xml file, using XSL transofrm. Here is a a form to automatically make such conversion.

Papywizard main target is Nokia Internet Tablets, so keyboard shortcuts are dedicated for that plateform (but works fine with normal PC). Here are defined shortcuts:
- In main window:
|Right||Turn the head right (Yaw +)|
|Left||Turn the head left (Yaw -)|
|Up||Move the head up (Pitch +)|
|Down||Move the head down (Pitch -)|
|End||Set current position as end position|
|Home||Set current position as start position|
|Return||Open shooting dialog|
- In shooting dialog:
|Escape||Stop shooting - Return to main window|
- In all dialogs:
|-||Standard maemo behaviour|
|F6||Toggle fullscreen mode (no more activated)|
