DrawPile是一个开源的绘图程序，用于创建草图。其中，它使用户能够实时共享图纸，并在同一画面同时借鉴。 可以实现多人编辑一幅图片。它界面直观、布局简捷，支持bmp、pbm、png、ppm和xbm格式，在不进行协同工作的时间，也可以作为普通图形工具使用。
DrawPile 1.0.2, which has been recently released, coming with the below changes:
Fixed crash when smoother was set to zero
Server: added command line option to enable split recording mode (new recording for each snapshot)
Server: /force_snapshot command can now be used outside debug mode
Fixed stretched selection contents if selected area was (partially) outside the canvas
Chat URL autolinker now accepts more characters in the fragment identifier
Retcon simplification: just discard the local fork on conflict rather than replaying
Strokes are started immediately even when smoothing is enabled
Ports in autolinked URLs are now recognized
Dedicated server: added –welcome-message parameter
Fixed “reset size” for polygonal selections
Improved recording index file generation
Active selection is no longer cleared when switching from rectangle to lasso tool

Bugfix: remember selected listing server in session finder dialog

Smarter image sending: avoid sending blank images
New feature: area sampling for color picker
When opening a drawpile:// link, rather than connecting directly, the join dialog is shown
