| ===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 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.
| |
| | |
| | |
| ====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.

| | |
| :[[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. Circular stamps of reduced opacity will be produced at regular intervals on the current canvas layer based on the following settings:
| |
| | |
| | |
| ==Type==
| |
| | |
| Four brush types are provides that produce different results when using the mouse to interact with the canvas view.
| |
| | |
| | |
| ===Freeform===
| |
| | |

| | |
| :[[File:CanvasToolsPaintBucketFill01.png|thumb| 220px |none|Fill Bucket Tool.]]
| |
| | |
| 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 mouse cursor on a point of the canvas view. The result of this tool can be controlled using 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.
| |
| | |
| | |
| ==Restrict to Canvas==

| :[[File:CanvasToolsFreeTransform01.png|thumb| 224px |none| Free Transform Tool.]]
| |
| | |
| The free transform tool provides the facility to interactively move, rotate and scale the currently selected layer(s), alternatively if a selection is active then the area the selection is covering the currently deleted layer will be transformed. A box bounding the currently selection area or selected layer(s) with handles at the corners and edge centres will be displayed.
| |
| | |
| To perform transforms the following methods can be used:
| |
| * Move: Click and drag the mouse cursor inside the bounding box in the canvas view. When the shift key is held movement will be constrained horizontally and vertically.
| |
| * Rotate: Click and drag the mouse cursor outside the bounding box in the canvas view.
| |
| * Scale: Click and drag the mouse 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 mouse cursor in the transform area bounding box.
