Signing or Drawing on the Prints
After taking photos, users can sign or draw on the print layout before it is printed. Enable this by selecting Sign or draw on photos before printing in the Output Settings dialog.
Drawing tools
The print layout is displayed full screen with a menubar on the left. Tools available to users:
- Colour palette — tap the palette icon to choose pen colour
- Line width — tap the line width icon and use the slider to adjust brush size
- Emojis/stickers — tap the emoji icon to place, move, resize, and rotate stickers
- Frames — tap the frames icon to apply a frame overlay
- Undo — tap the undo arrow to reverse the last action
- Redo — tap the redo arrow to redo an undone action
- Clear — tap the trashcan to start over
- Print — tap the printer icon to accept and print
- Cancel — tap the X to reject and return to the ready screen
Frames
Frames are PNG overlay images in the photo booth images folder with filenames starting with frame_ (e.g. frame_1.png, frame_2.png). They should be the same pixel size as the print layout with transparent areas where photos are positioned.
Customising the screen appearance
- Place
usermodifyprint.jpgin the photo booth images folder to replace the default black background. - Place
usermodifyprint_overlay.pngto add an instruction overlay visible on screen but not in the final print. - Replace icon PNG files in the
iconssubfolder of the installation folder, or place replacements in the photo booth images folder.
