Paint tools – Paint Can

  • This tool allows you to fill an area of an image based on color similarity. This tool also provides additional settings for more precise control. 

How to use
  • Click left mouse button anywhere in the image and the paint can will fill an area around the pixel you clicked.  

  • The paint can fills only pixels which have similar color. You can set tolerance of the similarity (1). Higher the tolerance more pixels are classified as similar. 

  • If you apply the pain can on completely transparent pixel then similarity is based on transparency (alpha). 

  • Only one layer can be selected during the paint. 

  • If some areas of the image are selected then paint will be only applied to the selected areas.
