Some common features that exist in similar software, such as text layers, gradients, and shape tools, are not implemented, as SAI focuses on drawing and painting, while the final composition is often done using another application. This has been erroneously repeated in some review articles and user provided tutorials around the web, including this Wikipedia article at one point.
Many fairly experienced users assume that the transform tools do not work at all on vector layers. Those points remain selected until the menu is opened again and clear selected points is clicked, even if another raster selection is made. After creating a raster selection by whatever means, the user must click selection on the menu bar and then click either select points or select strokes from the drop down menu after which the selected points are highlighted and are affected by the transformation tools as expected. Second, to apply the transform tools to a selection on a vector layer requires a non-obvious additional step. Effectively the 'rectangular selection' tool button (a dotted rectangle in the tool palette) is also the 'make transform tools visible' tool button. But it does not matter how a selection is initially created, selecting the rectangular selection tool will then show the transformation options which will work fine with it. There are two caveats with using the transform tools that often confuse new users and are not made clear by SAI's sparse included English documentation.įirst, SAI includes several tools for creating a selection, but only the rectangular (rubber band) selection tool shows the transformation options.

Any series of transforms can be set up and then applied at once to a specific selection minimizing the softening of the image.

SAI comes with a full set of transformation tools that can work on selections, including move, resize, rotate, and a free (perspective) transform. There is also a selection brush tool, which can be customized like the drawing brush. Selection tools include the simple square selection, the lasso, and magic wand, which can be configured for anti-aliasing. There is also a pen movement and pressure smoothing feature which can be manually configured as to how much effect it has. This allows one to add shading and highlights to an area without creating new masks for the additional layers. In addition to this, layers can be masked by clipping them to a lower layer. Work can be done on separate layers, which can be grouped and have opacity masks. There is also a set of vector drawing tools intended for inking, which, like the raster tools, can be configured to be pen pressure-sensitive. Various raster drawing tools are implemented, such as the Airbrush, Watercolor, Pen, and Marker, which can all be easily customized, and stored in slots in the user interface of the application. Colors can be stored in the swatches panel. An application-wide scratchpad (which can be used as a color mixing panel) is provided, which is saved between sessions. It is also possible to open multiple viewports to the same document. The toolbar on the top part of the screen also includes a button to mirror the drawing view without mirroring the actual drawing. The drawing canvas can be both zoomed and rotated using the sliders on the navigator or the hotkeys configured on the keyboard. The user interface allows multiple documents to be opened at the same time. SAI is a lightweight painting application.
