Picture Tubes
Picture tubes are graphic images with no background. They are often used as a starting point for complex images; that is, they are combined with other image elements to produce a final work. Tubes can also be regarded as graphic brushes based on a pre-created image; this was their original use. Instead of leaving a trace of color on the canvas, they would leave a trail of images. Popular tube subjects include alphabets, human (also known as dollz), animal and toy figures, flowers, love messages and seasonal symbols.
The tube system originated with PSP Pro version 5. Native tube files may be in .tub, .psp, .pspimage, and .psptube formats. XnView, IrfanView, and TubeEx are separate graphics programs that can open tube files (.tub) and save them as .png files for use in other programs.

Famous quotes containing the word picture:
“He is no mystic, either, more than Newton or Arkwright or Davy, and tolerates none. Not one obscure line, or half line, did he ever write. His meaning lies plain as the daylight.... It has the distinctness of picture to his mind, and he tells us only what he sees printed in largest English type upon the face of things.”
—Henry David Thoreau (1817–1862)
