| ===Paint Brush Tool===
| |
| | |
| | |
| :[[File:CanvasToolsPaintBrush01.png|thumb| 220px |none|]]
| |
| | |
| The paint brush tool provides an interactive tool to manipulate the pixel colours of areas of the current [[Canvas]] layer. Brush stamps of the current tool colour will be produced at regular intervals on the current Canvas Layer to produce the illusion of a brush stroke based on the following settings:
| |
| | |
| | |
| ====Type====
| |
| | |
| Four brush types are provides that produce different results when using the cursor to interact with the canvas view.
| |
| | |
| * '''Freeform:''' Clicking and dragging the cursor in the canvas view will produce brush stamps under the cursor at regular intervals as it is moved.
| |
| * '''Line:''' Dragging the cursor between two points in the canvas view will produce a line comprising of brush stamps at regular intervals. A dashed line is provided during tool interaction to indicate where the output stamps will be produced. Holding the Shift key during tool interaction will snap the produced line to Horizontal or Vertical orientation.
| |
| * '''Rectangle:''' Dragging the cursor between two points in the canvas view will produce a rectangle comprising of brush stamps at regular intervals. A dashed line is provided during tool interaction to indicate where the output stamps will be produced. Holding the Shift key during tool interaction will snap the produced rectangle to be a square.
| |
| * '''Oval:''' Dragging the cursor between two points in the canvas view will produce an oval comprising of brush stamps at regular intervals. A dashed line is provided during tool interaction to indicate where the output stamps will be produced. Holding the Shift key during tool interaction will snap the produced rectangle to be a circle.
| |
| | |
| | |
| ====Flow====
| |
| | |
| The flow level controls the transparency of each individual brush stamps. A flow level of 100% will provide a strong brush stroke, a lower flow level will provide a more natural fluid brush stroke.
| |
| | |
| | |
| ====Opacity====
| |
| | |
| The opacity level controls transparency of the complete brush stroke. An opacity level lower than 100% provides maximum strength of the brush stroke, a lower opacity will not allow any element of a brush stoke to be above the specified opacity even if the same area is interacted with multiple times.
| |
| | |
| | |
| ====Radius====
| |
| | |
| The radius control specifies the maximum radius of brush stamps in pixels. If a pressure sensitive input device is used and pressure sensitivity settings are active then the radius of brush stamps may be smaller than this specified radius.
| |
| | |
| | |
| ====Hardness====
| |
| | |
| The hardness level controls the amount a brush stamp fades around it's edge. A hardness of 100% will mean no edge fading with happen. 0% hardness will produce a brush stamps opacity to fade from the completely way from centre to edge.
| |
| | |
| | |
| ====Spacing====
| |
| | |
| The spacing level control specifies the spacing between brush stamps based on a brush stamps current radius. A level of 100% will cause no brush stamp overlapping, a low spacing level will cause brush to overlap more tightly.
| |
| | |
| | |
| ====Smoothing====
| |
| | |
| When the freeform brush type is active this mode optional provides a smooth quadratic interpolation between the input cursors sample points.
| |
| | |
| Under normal operation this option is recommended to be active.
| |
| | |
| | |
| ====Stabilisation====
| |
| | |
| Causes the removal of unstable movements in the brush stroke by limiting the maximum sample rate of cursor movement producing a smoother brush curves.
| |
| | |
| | |
| ====Pressure====
| |
| | |
| If a pressure sensitive input device is being used such as a Wacom graphics tablet then these options allow the input pressure is dynamically affect the brush tool output. The following options are available:
| |
| | |
| * '''Disabled:''' Even if a pressure sensitive input device is available the pressure input will be ignored.
| |
| * '''Flow:''' The amount of pressure input is multiplies brush flow amount. The result is updated as each brush stamp is produced.
| |
| * '''Radius:''' The amount of pressure input is multiplies brush radius amount. The result is updated as each brush stamp is produced.
| |
| * '''Flow and Radius:''' Both the flow and radius amounts of the brush are both modified as specified above.
| |
| | |
| | |
| ====Behind====
| |
| | |
| When active the paint brush output will be composited below the current layer pixel data.
| |
| | |
| | |
| ===Eraser Brush Tool===
| |
| | |
| | |
| :[[File:CanvasToolsEraserBrush01.png|thumb| 222px |none|]]
| |
| | |
| | |
| The eraser brush tool provides an interactive tool to manipulate the pixel transparency of areas of the current [[Canvas]] Layer.
| |
| | |
| Brush stamps of reduced opacity will be produced at regular intervals on the current Canvas Layer to produce the illusion of a brush stroke based on the following settings:
| |
| | |
| | |
| ====Type====
| |
| | |
| Four brush types are provides that produce different results when using the cursor to interact with the canvas view.

| | |
| | |
| :[[File:CanvasToolsPaintBucketFill01.png|thumb| 220px |none|]]
| |
| | |
| | |
| The fill bucket tool will flood areas of the current [[Canvas]] Layer of similar colours with the current Canvas tool colour radiating from a selected seed point.
| |
| The seed point of the colour fill is specified by clicking the cursor on a point of the Canvas Viewport. The results of this tool can be controlled with the following settings:
| |
| | |
| | |
| ====Tolerance====
| |
| | |
| The percentage level that controls the level of difference from the point selected on the current canvas layer that will be flooded with the tool. A value of 100% will flood all pixels in the current layer regardless of their difference from the seed point colour. A value of 0% will only allow pixels of the exact same value of the seed point to be flooded.
| |
| | |
| | |
| ====Restriction====
| |
| | |
| The output area that can be flooded by the fill bucket tool will be restricted using one of the following options:
| |
| | |
| * '''Restrict to Canvas Checkbox:''' Inside the Canvas area boundary.
| |
| * '''Restrict to Range Checkbox:''' The entered width and height values centring around the seed point.

| ===Move Tool===
| |
| | |
| | |
| :[[File:CanvasToolsMove01.png|thumb| 220px |none|]]
| |
| | |
| | |
| Interactively move the currently selected Canvas Layer(s), alternatively if a selection is active then the area which the selection is covering of the current Canvas Layer will be moved.
| |
| | |
| The amount of offset used for the move is determined by the distance the cursor is clicked and dragged in the canvas view.
| |
| | |
| When the shift key is held down during tool interaction movement will be constrained to horizontal and vertical movement.
| |
| | |
| The 'Arrow' keys can also be pressed to 'Nudge' the Move Tool action a single pixel in the corresponding direction.

| | |
| :[[File:CanvasToolsFreeTransform01.png|thumb| 224px |none|]]
| |
| | |
| | |
| Interactively Move, Rotate and Scale the currently selected Canvas Layer(s), alternatively if a selection is active then this area of the currently Layer will be transformed.
| |
| | |
| A box bounding of the currently selection area or selected Canvas Layer(s) with handles at the corners and edge centres will be displayed in the Canvas View.
| |
| | |
| To perform transforms the following methods can be used, a corresponding cursor icon representing the method in the areas where available:
| |
| | |
| * '''Move:''' Drag the cursor inside the bounding box. When the shift key is held movement will be constrained horizontally and vertically.
| |
| * '''Rotate:''' Drag the cursor outside the bounding box.
| |
| * '''Scale:''' Drag the cursor from any of the handles at the corners or edge centres of the bounding box. When the shift key is held and a corner handle is dragged the scale will be contained to the same amount in both width and height.
| |
| | |
| During interaction of the tool any transforms will be previewed using 'Bilinear interpolation'. When a transform operation is completed high quality 'Bicubic interpolation' is used.
| |
| | |
| To complete a transform operation the following methods can be used:
| |
| * Press enter key.
| |
| * Double click cursor in the transform area bounding box.
| |
| * Switch to another Canvas Tool or perform another action (a confirmation Dialog Window will be displayed to confirm the transform).
