Advertisement In contrast to raster bitmap graphics editors such as Photoshop or Gimp, Inkscape stores its graphics in a vector format. Vector graphics is a resolution-independent description of the actual shapes and objects that you see in the image. A rasterization engine uses this information to determine how to plot each line and curve at any resolution or zoom level. Contrast that to bitmap raster graphics which is always bound to a specific resolution and stores an image as a grid of pixels. Inkscape can import and display bitmap images, too.

Lightness Alpha The Threshold in per cent units controls how large must be color difference at a point compared to the initial click point to stop the fill. Zero tolerance means only the area of strictly the same color will be filled; the larger the tolerance, the easier it will be for the fill to leak into adjacent different-color areas. Setting a positive outset causes fill paths to be larger than the filled bitmap area good for eliminating anti-aliasing errors , while setting a negative outset causes the path to be smaller.
With the Close gaps parameter, you can make the Paint Bucket tool ignore any gaps in the area boundaries that would normally cause the fill to spill out of the desired area. There are four settings to auto gap: None Small close gaps up to 2 pixels in size Medium 4 pixels Large 6 pixels Note that setting this parameter to other than None may slow down noticeably the filling of large areas. Click and drag performs filling from all of the points that you pass while dragging you will see your path visualized by a red line.
This lets you easily fill an area occupied by a gradient or blur - just drag from the darkest to the lightest points in the area you want to fill. Tweak tool The Tweak tool is an exciting new way to edit drawings which largely blurs the distinction between vector and raster editing. This makes the tool act softly and smoothly. You can also apply it to groups of objects; it will go into groups and act on individual objects inside groups.
You can also change width by Left and Right arrow keys same as in the Calligraphy tool at any time including during action as well as Home and End. Also, as in Calligraphy tool, the visible width of the brush is independent of zoom; simply zooming in or out is often easier than adjusting the width if you want to cover a smaller or larger area of the drawing.
Force The next control is Force which adjusts the power of the action, also in the range from 1 to You can also change width by Up and Down arrow keys at any time including during action.
If you have a pressure-sensitive tablet and your "Use pressure" button on the right-hand end of the controls bar is on, then the force will also depend on how hard you actually press your pen into your tablet, changing in the range from zero to whatever you set in the Force control.
If all you have is a mouse, then the force will be constant but still settable by the Force control. Some of these modes change the shapes of paths while others affect the colors of objects. All these modes share the Width and Force controls but otherwise are quite different. If applied to a shape or text object, the tool converts them to paths automatically. While not very useful for technical drawings, tweaking paths will be indispensable for artistic uses of Inkscape - cartoons, drawings, sketches, anime, etc.
This new functionality is somewhat similar to the tools such as "Pucker" and "Bloat" in the latest versions of Adobe Illustrator. This default mode of the tool, Push , simply displaces the part of the path under the cursor in the direction of the drag. The path behaves like soft jelly, bending and bulging smoothly and naturally. For parallel-stroke hatching engraving done in the Calligraphy tool, pushing is an easy way to bend, pinch, or curve the entire hatching uniformly.
This is similar to the Inset and Outset commands, except that the Tweak tool can act on a part of a path instead of the whole path. Also, the ends of Calligraphy pen strokes are often far from ideal - they may be too blunt or have unsightly bends or blobs.
This is where the Tweak tool may help. Select all the strokes in a hatching pattern and apply a light Shrink action where you want the lines to become thinner and the hatching to become lighter , up until total disappearance.
Conversely, applying Grow makes strokes wider i. Of course, shrinking and growing are useful not only for calligraphic strokes.
Same as with Push, with Shrink and Grow you can sculpt any path, spawning smooth treacle-like appendages with Grow and carving holes with Shrink. Unlike the "node sculpting" mode in the Node tool, however, this does not require adding new nodes to the shape. The Attract and Repel modes work by moving each affected point on a path towards Attract or from Repel the cursor point.
These modes are similar to the Pinch effect in AI; you can use them for various central-symmetric distortions in parts of your paths. The Roughen mode does exactly this: roughens the edge of the path without changing its overall shape. Slight roughening simply makes the edge crooked and uneven; strong roughening tears and explodes the edge into random blobs and splotches.
Note that this operation, especially with high Fidelity, adds a lot of nodes which increases the size of your SVG document and may slow down Inkscape considerably.
See the screenshot at  for a few examples of using the path editing modes of the Tweak tool. These distortions are similar to those that a Simplify command produces.
The Fidelity value also in the range from 1 to , default is 50 allows you to control the amount of these distortions. With a higher fidelity, the distortions are less noticeable, but the path may end up having a lot of nodes which inflates up the SVG size and slows down Inkscape. The best value of Fidelity depends on the nature of your artwork. If, however, you are pushing or inflating a text string as a single path and want the letters outside the distorted area to remain crisp and clean, you will need to raise fidelity to 80 or more.
For 4 , it helps to increase Fidelity. Also, you can undo the bad change and try again with less pressure on the pen - if you do your thinning in several light touches instead of one heavy press, usually you will be able to get the desired result without the buggy behavior.
Fortunately, livarot is scheduled for replacement by lib2geom, a new library now in development, so hopefully these issues will be addressed then. Color editing modes The Color Paint and Color Jitter modes, unlike the path editing modes, change the colors of objects instead of their shapes.
Yet they share enough common features with the path editing modes to be part of the same tool: These modes also use a circular soft-edged brush controlled by the Width and Force parameters on the Controls bar and affected by the pen pressure if you have a pressure-sensitive tablet. Color Paint applies the style of the tool to the selected objects under the brush.
This mode allows you to literally paint over objects, shifting their colors towards the target style of the tool. This speed of this gradual transition depends on both Force parameter and pen pressure; also, objects touched by the periphery of the brush are less affected than those hit by the brush center. Overall, using this tool is very similar to a soft brush in a raster editor such as Gimp or Photoshop. Color Jitter mode does not apply any color, but instead jitters randomizes the colors of the objects it touches.
The force of the action determines how strong is the randomization, i. Both modes work on flat fills and gradients; for gradients, the tool takes into account not only the position of the entire object with gradient, but also the position of each gradient stop relative to the brush. This means that, for example, you can change the blue color only in an object filled with blue-red gradient simply by painting over its blue end with a brush small enough to not touch the red.
Note that color tweaking does not create gradients on objects that used flat color before, but only adjusts existing gradients in the drawing.
See the screenshot at  for a few examples of using the color editing modes of the Tweak tool. For example, if you want to raise the saturation of some part of your drawing without changing the hue, select some maximum-saturation color e. Usage notes Color painting with Tweak tool is similar, but not exactly analogous to bitmap painting.
Even though the tool itself works as a soft brush, it still applies its color to vector objects, which behave as vector objects usually do. We foresee a "fracture" command in one of the next versions of Inkscape which will help you turn a monolithic object into a mosaic of small fragments that will be then easy to paint with Tweak tool.
Still, even with this limitation, color painting is a novel way of dealing with vector drawings which allows you to quickly and intuitively make adjustments which would be awkward and slow with traditional approach.
Drawings containing patterns or scatterings of small independent objects are best suited for color painting with Tweak tool. Moreover, color tweaking can be useful for compositions with a few objects or even for single objects. Unlike all other color selection methods, painting with the Tweak tool implements the color mixing metaphor which is much more familiar to traditional artists than RGB sliders or even the color wheel.
For example, start with a rectagle of pure blue color; then, pick different colors by Color Paint and apply light touches with minimum Force and minimum pen pressure: add a little green, a little brown, a little yellow, etc.
Similarly, you can whiten or blacken any hue by admixing white or black. Just select all in all layers, zoom out, choose a large brush width so it covers all of the drawing, and apply a little color tweaking with minimum Force that will therefore affect all visible objects. However, very often it is used to create drawings or objects that appear three-dimensional.
The new 3D box tool helps you create such drawings by automating the most common operation: creating a box in a given 3D perspective. The tool automatically ensures that all sides of the box lie on the corresponding perspective lines. Adjust any of its 3 dimensions by handles. With Shift, the functions of handles on front and back sides are reversed. With Ctrl, the side-resizing handles snap to the coordinate axes or diagonals. Move a 3D box "in perspective" by dragging its center; without modifiers, movement occurs within the XY-plane press Ctrl to constrain the movement to the directions of the coordinate axes or diagonals , with Shift the box moves parallel to the Z-axis.
Adjust the vanishing points of a perspective by dragging them on the canvas see below or toggling their states; all boxes sharing this perspective are affected by a vanishing point move. When several boxes are selected, all vanishing points of their associated perspectives are shown on the canvas. If vanishing points of different perspectives coincide, they are combined in a single "dragger".
Moving this dragger moves all the vanishing points simultaneously and transforms the associated boxes accordingly. Note that some non-selected boxes may also be reshaped if their perspectives share the same vanishing point. On the other hand, when a vanishing point being dragged comes close enough to another one, both snap together and are combined in a single dragger.
You can of course transform the entire box or any face in it using Selector or Node tools. Closing parentheses rotate clockwise and opening parentheses rotate counterclockwise. The angle of rotation is taken from the preferences. Pressing Alt reduces the amount of rotation to 1 screen pixel.
Gradient Tool Selecting multiple stops More than one gradient stop can be selected at a time. Shortcuts for working with multiple stop selections are generally modeled on the Node tool. Multiple selected stops: Can be moved together by mouse drag or by arrow keys. Can be deleted at the same time by pressing Del. An always up-to-date description of the current handle selection is provided in the statusbar in the Gradient tool, including the number of selected handles and the type of the single selected handle , as well as the total number of handles and selected objects.
Editing intermediate stops Intermediate stops in gradients can be added, deleted, and edited on canvas previously this was only possible in the Gradient Editor dialog. Also, you can drag-and-drop a color from the palette onto the gradient line to create a new stop with this color.
Dropping a color on an existing stop changes the color of that stop. When two or more adjacent stops are selected, pressing Ins adds stops in the middles of all selected stop intervals. Intermediate stops can be mousedrag ged or moved by arrow keys along their gradient line, within the limits of the adjacent unselected stops or end handles. Dragging with Alt moves the selected stops depending on how close each one is to the stop being dragged, using a smooth bell-like curve similar to the node sculpting feature in Node tool.
When you delete an end stop, the nearest intermediate stop becomes the new end stop of the gradient without moving - i. This makes it much easier to view and change opacity of gradient handles using only the selected style indicator in the statusbar.
