Paint Tool SAI is a popular art program with a variety of features and tools. One of the challenges users face is centering an image or object within the canvas. Centering an image can be achieved by using the alignment and resizing tools. The alignment tool allows users to align objects in relation to another object or to the design area. The resizing tool allows users to hold Ctrl and drag to use the centerline of the objects as a stationary point. Additionally, centering the canvas using the square buttons on the navigator panel can help position the symmetry tool in the center.

Use the 'Select' and 'Deselect' tools to manipulate the image without going outside the boundaries
Paint Tool SAI has a range of selection tools that can be used to manipulate an image without going outside the boundaries. The selection tools include the Select brush, the Magic Wand, the Lasso, and the Rectangle Selection tool.
The Select brush allows you to change its size, opacity, and pen pressure, and even add texture. You can use it to select areas that you want to move, rotate, scale, or paint without going beyond the boundaries. The Deselect tool, or the desel pen, acts as an eraser and has the same settings as the Select brush. It is useful for correcting selecting mistakes.
The Magic Wand tool has three detection modes: Transparency (Strict), Transparency (Fuzzy), and Color Difference. The latter is the most useful of the three as it selects things depending on their color. The “Color diff.” bar allows you to choose how strict the tool should be. The Lasso tool also falls under the selection tools category.
The Rectangle Selection tool gives you access to all transformation tools, such as scaling and rotating. You can also use the Increment tool to make borders. Take whatever you’re planning on putting a border around, hold Ctrl, and click the layer box it's on. This will select everything on that layer. Then press Increment a few times depending on how thick you want the border to be.

Use the 'Align' tool to align the image in relation to another object or the design area
To centre an image in Paint Tool SAI, you can use the Align tool, which allows you to align objects in relation to another object or the design area. Here's a step-by-step guide on how to use the Align tool:
Firstly, select the objects you want to align. You can do this by either dragging a bounding box around the objects or by clicking on them while holding the Shift key. If you use the bounding box method, the first object that was created will be the stationary object. If you select the objects by clicking and holding Shift, the first object selected will be the stationary object.
Once you've selected the objects, you can choose how you want them to align. From the Arrange menu, go to Align and select the desired alignment. You can also right-click on the selected objects, choose Align, and then select the alignment you want. For example, if you want to centre an object on the canvas, you would select the object, right-click, choose Align, and then select "Center" or a similar option.
If you have set a margin on your canvas, the objects will be aligned to that margin. You can also use the Align tool to align objects in relation to another object. For instance, if you want to centre one object in relation to another, you would select both objects, then choose the alignment option that centres them in relation to each other.
The Align tool in Paint Tool SAI gives you a lot of flexibility in positioning and aligning objects on your canvas. By following these steps, you can easily centre an image or object in relation to another object or the design area.

Hold Ctrl and drag to use the object's centreline as a stationary point
To center an image in Paint Tool SAI, hold Ctrl and drag to use the objects' centerline as a stationary point. This feature allows you to keep the centerline of the object fixed while adjusting its position. By holding down the Ctrl key and dragging the object, you can easily align it with the center of the canvas or another reference point. This method provides a precise and efficient way to center objects within your artwork.
Holding Ctrl and dragging is a useful technique for various scenarios when working with objects in Paint Tool SAI. For example, if you have multiple objects that you want to align with each other, using the Ctrl drag method can help you position them accurately. This approach ensures that the centerline remains fixed, providing a stable reference point for your adjustments.
Additionally, when working with complex compositions or detailed artwork, the ability to center objects becomes crucial. By holding Ctrl and dragging, you can fine-tune the placement of objects, ensuring they are symmetrically positioned or evenly spaced. This technique is especially helpful when creating symmetrical patterns, collages, or layouts where balance and alignment are essential.
The "Hold Ctrl and drag" method is a versatile tool that can be applied to various creative tasks in Paint Tool SAI. Whether you're designing a logo, creating a digital painting, or composing a collage, the ability to center objects with precision adds a level of professionalism and polish to your work. It simplifies the process of arranging elements within your artwork, saving you time and effort.
Overall, the "Hold Ctrl and drag" technique in Paint Tool SAI is a powerful tool for centering objects and using the objects' centerline as a stationary point. It enables you to make precise adjustments, align objects symmetrically, and create visually appealing compositions. With this method, you can easily center images and objects, enhancing the overall presentation and impact of your digital artwork.

Use layers to change parts of the artwork without touching the rest
Layers in PaintTool SAI are a powerful feature that allows you to work on different parts of your artwork separately, without affecting the rest of the image. This means you can make changes or corrections to specific elements without disturbing other parts of your artwork. Think of layers like sheets of glass stacked on top of each other, where you can paint on each sheet individually while still seeing what's on the others.
To access layers in PaintTool SAI, look for the Layer Panel on the left side of your window. By default, it appears as a large grey box with a small purple box labelled "Layer 1". You can change the position of the Layer Panel by going to Window > Show Navigator and Layer Panels on Right Side. This allows you to place it on either the left or right side of your canvas, depending on your preference.
Creating a new layer is simple. In the Layer Panel, you'll find two icons: the “New Layer” button, which creates a normal layer, and the “New Linework Layer” button, which provides a different set of tools. You can also create folders for your layers by clicking the “New Layer Set” button, allowing you to organise and control groups of layers together.
Each layer has an eye icon that lets you toggle its visibility. This is useful if you want to focus on a specific layer without the others getting in the way. You can also adjust the opacity of each layer, controlling how much you can see through it. Additionally, you can apply various textures and effects to each layer, customising their intensity and scale to achieve your desired artistic vision.
Working with layers in PaintTool SAI is a great way to separate different elements of your artwork, giving you more control and flexibility in your creative process. By using layers effectively, you can easily make changes to specific parts of your artwork without touching the rest.

Use the 'Transform' tool to move the selection until the rotation point is fixed
To center an image in Paint Tool SAI, you can use the Transform tool to move your selection until the rotation point is fixed. This process involves a few steps:
First, make sure you have an image or selection that you want to center. You can use the Select tool, which is represented by a dotted square, to make your selection. Click and drag the dotted square around the area you want to center.
Once you have your selection, you can access the Transform tool by clicking on the selected area. This will bring up buttons for various transformation options. Look for the Transform button and click on it.
Now, you can begin to adjust your selection. The Transform tool allows you to move, rotate, scale, and flip your selection. To center your image, you will primarily be concerned with moving and rotating it.
Move your selection by clicking and dragging it to the desired location. You can adjust its position on the canvas until it is centered relative to your preferred reference point.
If needed, you can also rotate your selection. The rotation point is the center point around which the image will turn. By default, the rotation point is set to the top left of the layer. You can fix the rotation point by moving it to the center of your image. This ensures that when you rotate the image, it stays in place without shifting to the left or right.
Play around with the Transform tool's options and adjust your selection until you are happy with its placement. The Transform tool is a powerful feature in Paint Tool SAI that allows you to make precise adjustments to your images and creations.
