Introduction to Krita coming from Paint Tool Sai¶
How do you do that in Krita?¶
This section goes over the functionalities that Krita and Paint Tool Sai share, but shows how they slightly differ.
Right click color picker¶
You can actually set this in Pick Foreground Color from Merged Image to get a window to set it to .. Just double-click the entry that says Ctrl + shortcut before
Krita 3.0 actually has a Paint-tool Sai-compatible input sheet shipped by default. Combine these with the shortcut sheet for Paint tool Sai to get most of the functionality on familiar hotkeys.
This is in the tool options docker of the freehand brush. Use Basic Smoothing for more advanced tablets, and Stabilizer is much like Paint Tool Sai’s. Just turn off Delay so that the dead-zone disappears.
So one of the things that throw a lot of Paint Tool Sai users off is that Krita uses checkers to display transparency, which is actually not that uncommon. Still, if you want to have the canvas background to be white, this is possible. Just choose Background: As Canvas Color in the new image dialogue and the image background will be white. You can turn it back to transparent via menu item. If you export a PNG or JPG, make sure to uncheck Store alpha channel (transparency) and to make the background color white (it’s black by default).
Like Sai, you can quickly turn a black and white image to black and transparent with the Filter: Color to Alpha dialog under menu item.
Another, somewhat amusing misconception is that Krita’s brush engine is not very complex. After all, you can only change the Size, Flow and Opacity from the top bar.
This is not quite true. It’s rather that we don’t have our brush settings in a docker but a drop-down on the toolbar. The easiest way to access this is with the F5 key. As you can see, it’s actually quite complex. We have more than a dozen brush engines, which are a type of brush you can make. The ones you are used to from Paint Tool Sai are the Pixel Brush (ink), The Color Smudge Brush (brush) and the filter brush (dodge, burn).
A simple inking brush recipe for example is to take a pixel brush, uncheck the Enable Pen Settings on opacity and flow, and uncheck everything but size from the option list. Then, go into brush-tip, pick Auto Brush from the tabs, and set the size to 25 (right-click a blue bar if you want to input numbers), turn on anti-aliasing under the brush icon, and set fade to 0.9. Then, as a final touch, set spacing to ‘auto’ and the spacing number to 0.8.
You can configure the brushes in a lot of detail, and share the packs with others. Importing of packs and brushes can be done via the
Erasing is a blending mode in Krita, much like the transparency mode of Paint Tool Sai. It’s activated with the E key or you can select it from the Blending Mode drop-down box.
Krita has a lot of Blending modes, and thankfully all of Paint Tool Sai’s are amongst them except binary. To manage the blending modes, each of them has a little check-box that you can tick to add them to the favorites.
Multiple, Screen, Overlay and Normal are amongst the favorites. Krita’s Luminosity is actually slightly different from Paint Tool Sai’s and it replaces the relative brightness of color with the relative brightness of the color of the layer.
Sai’s Luminosity mode (called Shine in Sai2) is the same as Krita’s Luminosity/Shine (SAI) mode, which is new in Krita 4.2.4. The Sai’s Shade mode is the same as Color Burn and Hard Mix is the same as the Luminosity and Shade modes.
- Lock Alpha
This is the checker box icon next to every layer.
- Clipping group
For Clipping masks in Krita you’ll need to put all your images in a single layer, and then press the ‘a’ icon, or press the Ctrl + Shift + G shortcut.
- Ink layer
This is a vector layer in Krita, and also holds the text.
These grayscale layers that allow you to affect the transparency are called transparency masks in Krita, and like Paint Tool Sai, they can be applied to groups as well as layers. If you have a selection and make a transparency mask, it will use the selection as a base.
- Clearing a layer
This is under, but you can also just press the Del key.
Mixing between two colors¶
If you liked this docker in Paint Tool Sai, Krita’s Digital Color Selector docker will be able to help you. Dragging the sliders will change how much of a color is mixed in.
What do you get extra when using Krita?¶
More brush customization¶
You already met the brush settings editor. Sketch brushes, grid brushes, deform brushes, clone brushes, brushes that are textures, brushes that respond to tilt, rotation, speed, brushes that draw hatches and brushes that deform the colors. Krita’s variety is quite big.
More color selectors¶
You can have HSV sliders, RGB sliders, triangle in a hue ring. But you can also have HSI, HSL or HSY’ sliders, CMYK sliders, palettes, round selectors, square selectors, tiny selectors, big selectors, color history and shade selectors. Just go into Docker: drop-down box, to change the shape and type of your main color selector., select an option in the
You can call the color history with the H key, common colors with the U key and the two shade selectors with the Shift + N and Shift + M shortcuts. The big selector can be called with the Shift + I shortcut on canvas.
Circles, rectangles, paths, Krita allows you to draw these easily.
Multibrush, Mirror Symmetry and Wrap Around¶
These tools allow you to quickly paint a mirrored image, mandala or tiled texture in no time. Useful for backgrounds and abstract vignettes.
The painting assistants can help you to set up a perspective, or a concentric circle and snap to them with the brush.
Locking the Layer¶
Lock the layer with the padlock so you don’t draw on it.
Quick Layer select¶
If you hold the R key and press a spot on your drawing, Krita will select the layer underneath the cursor. Really useful when dealing with a large number of layers.
This allows you to prepare your work for print, or to do tricks with the LUT docker so you can diagnose your image better. For example, using the LUT docker to turn the colors grayscale in a separate view, so you can see the values instantly.
Advanced Transform Tools¶
Not just rotate and scale, but also cage, wrap, liquify and non-destructive transforms with the transform tool and masks.
More Filters and non-destructive filter layers and masks¶
With filters like color balance and curves you can make easy shadow layers. In fact, with the filter layers and layer masks you can make them apply on the fly as you draw underneath.
This is the little circular thing that is by default on the right click. You can organize your brushes in tags, and use those tags to fill up the pop-up palette. It also keeps a little color selector and color history, so you can switch brushes on the fly.
What does Krita lack compared to Paint Tool Sai?¶
Variable width vector lines
The selection source option for layers
Dynamic hard-edges for strokes (the fringe effect)
No Preset-tied stabilizer
No per-preset hotkeys
I hope this introduction got you a little more excited to use Krita, if not feel a little more at home.
