Tutorial | AvançadoEste tutorial aborda os seguintes temas: copiar/colar, edição de nós, desenho à mão livre e desenho com curvas Bézier, manipulação de caminhos, operações booleanas, deslocamentos (comprimir/expandir), simplificação e ferramenta de texto.Use Ctrl+arrows, mouse wheel, or middle button drag to scroll the page down. For basics of object creation, selection, and transformation, see the Basic tutorial in Help⇒Tutorials.Técnicas de colarAfter you copy some object(s) by Ctrl+C or cut by Ctrl+X, the regular Paste command (Ctrl+V) pastes the copied object(s) right under the mouse cursor or, if the cursor is outside the window, to the center of the document window. However, the object(s) in the clipboard still remember the original place from which they were copied, and you can paste back there by Paste In Place (Ctrl+Alt+V).Another command, Paste Style (Shift+Ctrl+V), applies the style of the (first) object on the clipboard to the current selection. The “style” thus pasted includes all the fill, stroke, and font settings, but not the shape, size, or parameters specific to a shape type, such as the number of tips of a star.Yet another set of paste commands, Paste Size, scales the selection to match the desired size attribute of the clipboard object(s). There are a number of commands for pasting size and are as follows: Paste Size, Paste Width, Paste Height, Paste Size Separately, Paste Width Separately, and Paste Height Separately.Paste Size scales the whole selection to match the overall size of the clipboard object(s). Paste Width/Paste Height scale the whole selection horizontally/vertically so that it matches the width/height of the clipboard object(s). These commands honor the scale ratio lock on the Selector Tool controls bar (between W and H fields), so that when that lock is pressed, the other dimension of the selected object is scaled in the same proportion; otherwise the other dimension is unchanged. The commands containing “Separately” work similarly to the above described commands, except that they scale each selected object separately to make it match the size/width/height of the clipboard object(s).A área de transferência está disponível ao nível do sistema - pode-se copiar e colar objetos entre diferentes instâncias do Inkscape assim como entre o Inkscape e outros programas (estes têm de suportar o formato SVG).Desenhar à mão livre e caminhos regularesA maneira mais fácil de criar uma forma geométrica arbitrária é desenhá-la usando a ferramenta Lápis, ou seja, linhas à mão livre (F6):If you want more regular shapes, use the Pen (Bezier) tool (Shift+F6):With the Pen tool, each click creates a sharp node without any curve handles, so a series of clicks produces a sequence of straight line segments. click and drag creates a smooth Bezier node with two collinear opposite handles. Press Shift while dragging out a handle to rotate only one handle and fix the other. As usual, Ctrl limits the direction of either the current line segment or the Bezier handles to 15 degree increments. Pressing Enter finalizes the line, Esc cancels it. To cancel only the last segment of an unfinished line, press Backspace.Tanto na ferramenta Lápis como na ferramenta Caneta, o caminho atualmente selecionado mostra pequenas âncoras quadradas em ambas as extremidades. Estas âncoras permitem continuar o caminho (desenhando a partir de uma das âncoras) ou completá-lo (desenhando de uma âncora à outra) em vez de criar um novo caminho separado.Editar caminhosAo contrário das formas geométricas criadas pelas ferramentas de formas geométricas, as ferramentas de Caneta e de Lápis criam o que é conhecido como caminho. Um caminho é uma sequência de segmentos de linhas retas e/ou curvas Bézier que, como qualquer outro objeto do Inkscape, podem ter determinadas propriedades de preenchimento e traço. Porém, ao contrário de uma forma geométrica, um caminho pode ser editado arrastando-se livremente quaisquer um dos seus nós (e não apenas com alças pré-definidas) ou arrastando-se diretamente um segmento do caminho. Selecione o caminho seguinte e mude para ferramenta Nó (F2):You will see a number of gray square nodes on the path. These nodes can be selected by click, Shift+click, or by dragging a rubberband - exactly like objects are selected by the Selector tool. You can also click a path segment to automatically select the adjacent nodes. Selected nodes become highlighted and show their node handles - one or two small circles connected to each selected node by straight lines. The ! key inverts node selection in the current subpath(s) (i.e. subpaths with at least one selected node); Alt+! inverts in the entire path.Paths are edited by dragging their nodes, node handles, or directly dragging a path segment. (Try to drag some nodes, handles, and path segments of the above path.) Ctrl works as usual to restrict movement and rotation. The arrow keys, Tab, [, ], <, > keys with their modifiers all work just as they do in selector, but apply to nodes instead of objects. You can add nodes anywhere on a path by either double clicking or by Ctrl+Alt+click at the desired location.You can delete nodes with Del or Ctrl+Alt+click. When deleting nodes it will try to retain the shape of the path, if you desire for the handles of the adjacent nodes to be retracted (not retaining the shape) you can delete with Ctrl+Del. Additionally, you can duplicate (Shift+D) selected nodes. The path can be broken (Shift+B) at the selected nodes, or if you select two endnodes on one path, you can join them (Shift+J).A node can be made cusp (Shift+C), which means its two handles can move independently at any angle to each other; smooth (Shift+S), which means its handles are always on the same straight line (collinear); symmetric (Shift+Y), which is the same as smooth, but the handles also have the same length; and auto-smooth (Shift+A), a special node that automatically adjusts the handles of the node and surrounding auto-smooth nodes to maintain a smooth curve. When you switch the type of node, you can preserve the position of one of the two handles by hovering your mouse over it, so that only the other handle is rotated/scaled to match.Also, you can retract a node's handle altogether by Ctrl+clicking on it. If two adjacent nodes have their handles retracted, the path segment between them is a straight line. To pull out the retracted node, Shift+drag away from the node.Sub-caminhos e combinarUm caminho pode conter mais de um sub-caminho. Um sub-caminho é uma sequência de nós ligados uns aos outros. Por essa razão, se um caminho tem mais de um sub-caminho, nem todos os seus nós estão ligados. Abaixo à esquerda, 3 sub-caminhos pertencem a 1 único caminho composto; os mesmo 3 sub-caminhos à direita são caminhos independentes:Notar que um caminho composto não é o mesmo que um grupo. É um objeto que só pode ser selecionado como um todo. Se selecionar o objeto da esquerda acima e mudar para a ferramenta de Nó, verá nós em todos os 3 sub-caminhos. Na direita, pode apenas editar os nós de um caminho de cada vez.Inkscape can Combine paths into a compound path (Ctrl+K) and Break Apart a compound path into separate paths (Shift+Ctrl+K). Try these commands on the above examples. Since an object can only have one fill and stroke, a new compound path gets the style of the first (lowest in z-order) object being combined.Quando se combinam caminhos preenchidos que se sobrepõem, geralmente o preenchimento desaparecerá nas áreas onde os caminhos se sobrepõem:Esta é maneira mais fácil de criar objetos com buracos. Para comandos mais avançados em caminhos, ver "Operações Booleanas" mais adiante.Converter Objeto num caminhoAny shape or text object can be converted to path (Shift+Ctrl+C). This operation does not change the appearance of the object but removes all capabilities specific to its type (e.g. you can't round the corners of a rectangle or edit the text anymore); instead, you can now edit its nodes. Here are two stars - the left one is kept a shape and the right one is converted to path. Switch to node tool and compare their editability when selected:Moreover, you can convert to a path (“outline”) the stroke of any object. Below, the first object is the original path (no fill, black stroke), while the second one is the result of the Stroke to Path command (black fill, no stroke):Operações BooleanasThe commands in the Path menu let you combine two or more objects using boolean operations:Formas originaisUnion(Ctrl++)Diferença (Ctrl+-)(parte inferior menos a superior)Interseção(Ctrl+*)Exclusão(Ctrl+^)Divisão(Ctrl+/)Cortar Caminho(Ctrl+Alt+/)The keyboard shortcuts for these commands allude to the arithmetic analogs of the boolean operations (union is addition, difference is subtraction, etc.). The Difference and Exclusion commands can only apply to two selected objects; others may process any number of objects at once. The result always receives the style of the bottom object.The result of the Exclusion command looks similar to Combine (see above), but it is different in that Exclusion adds extra nodes where the original paths intersect. The difference between Division and Cut Path is that the former cuts the entire bottom object by the path of the top object, while the latter only cuts the bottom object's stroke and removes any fill (this is convenient for cutting fill-less strokes into pieces).Comprimir e expandirInkscape can expand and contract shapes not only by scaling, but also by offsetting an object's path, i.e. by displacing it perpendicular to the path in each point. The corresponding commands are called Inset (Ctrl+() and Outset (Ctrl+)). Shown below is the original path (red) and a number of paths inset or outset from that original:The plain Inset and Outset commands produce paths (converting the original object to path if it's not a path yet). Often, more convenient is the Dynamic Offset (Ctrl+J) which creates an object with a draggable handle (similar to a shape's handle) controlling the offset distance. Select the object below, switch to the node tool, and drag its handle to get an idea:Os objetos com Deslocamento Dinâmico memorizam o caminho original, assim estes não "se degradam" quando se altera a distância do deslocamento várias vezes. Quando não for preciso ajustá-lo mais, pode-se converter um objeto com deslocamento de novo num caminho.Ainda mais prático é um objeto com Deslocamento Ligado ao Original, similar ao objeto com Deslocamento Dinâmico mas que está ligado a um outro caminho que permanece editável. Pode-se fazer uma qualquer quantidade de objetos com Deslocamento Ligado ao Original baseados num só caminho. Abaixo, o caminho original está a vermelho, o deslocamento ligado ao original tem o traço preto e nenhum preenchimento, o outro tem preenchimento preto e nenhum traço.Select the red object and node-edit it; watch how both linked offsets respond. Now select any of the offsets and drag its handle to adjust the offset radius. Finally, notehow you can move or transform the offset objects independently without losing their connection with the source. SimplificaçãoThe main use of the Simplify command (Ctrl+L) is reducing the number of nodes on a path while almost preserving its shape. This may be useful for paths created by the Pencil tool, since that tool sometimes creates more nodes than necessary. Below, the left shape is as created by the freehand tool, and the right one is a copy that was simplified. The original path has 28 nodes, while the simplified one has 17 (which means it is much easier to work with in node tool) and is smoother.The amount of simplification (called the threshold) depends on the size of the selection. Therefore, if you select a path along with some larger object, it will be simplified more aggressively than if you select that path alone. Moreover, the Simplify command is accelerated. This means that if you press Ctrl+L several times in quick succession (so that the calls are within 0.5 sec from each other), the threshold is increased on each call. (If you do another Simplify after a pause, the threshold is back to its default value.) By making use of the acceleration, it is easy to apply the exact amount of simplification you need for each case.Besides smoothing freehand strokes, Simplify can be used for various creative effects. Often, a shape which is rigid and geometric benefits from some amount of simplification that creates cool life-like generalizations of the original form - melting sharp corners and introducing very natural distortions, sometimes stylish and sometimes plain funny. Here's an example of a clipart shape that looks much nicer after Simplify:OriginalSimplificação ligeiraSimplificação agressivaCriar textoO Inkscape é capaz de criar textos longos e complexos. No entanto, é também bastante útil para a criar de pequenos textos tais como cabeçalhos, faixas, logotipos, etiquetas, legendas de diagramas, etc. Esta secção é uma introdução muito básica sobre as capacidades de texto do Inkscape.Creating a text object is as simple as switching to the Text tool (F8), clicking somewhere in the document, and typing your text. To change font family, style, size, and alignment, open the Text and Font dialog (Shift+Ctrl+T). That dialog also has a text entry tab where you can edit the selected text object - in some situations, it may be more convenient than editing it right on the canvas (in particular, that tab supports as-you-type spell checking).Like other tools, Text tool can select objects of its own type - text objects -so you can click to select and position the cursor in any existing text object (such as this paragraph). One of the most common operations in text design is adjusting spacing between letters and lines. As always, Inkscape provides keyboard shortcuts for this. When you are editing text, the Alt+< and Alt+> keys change the letter spacing in the current line of a text object, so that the total length of the line changes by 1 pixel at the current zoom (compare to Selector tool where the same keys do pixel-sized object scaling). As a rule, if the font size in a text object is larger than the default, it will likely benefit from squeezing letters a bit tighter than the default. Here's an example:OriginalEspaçamento entre-letras diminuídoInspirationInspirationA variante com letras apertadas parece um pouco melhor para um cabeçalho, mas ainda não é perfeita: as distâncias entre as letras não são uniformes, por exemplo as letras "a" e "t" estão muito separadas enquanto que "t" e "i" estão muito próximas. A quantidade de tais espaçamentos imperfeitos (visíveis especialmente em tamanhos grandes de fontes) é maior em fontes de baixa qualidade que nas de alta qualidade; no entanto, em qualquer composição de texto e em qualquer fonte, provavelmente encontrará algumas letras que beneficiarão do ajuste do espaçamento.Inkscape makes these adjustments really easy. Just move your text editing cursor between the offending characters and use Alt+arrows to move the letters right of the cursor. Here is the same heading again, this time with manual adjustments for visually uniform letter positioning:Espaçamento entre-letras diminuído, com entre-letras em alguns pares de letras ajustado manualmenteInspirationIn addition to shifting letters horizontally by Alt+Left or Alt+Right, you can also move them vertically by using Alt+Up or Alt+Down:InspirationOf course you could just convert your text to path (Shift+Ctrl+C) and move the letters as regular path objects. However, it is much more convenient to keep text as text - it remains editable, you can try different fonts without removing the kerns and spacing, and it takes much less space in the saved file. The only disadvantage to the “text as text” approach is that you need to have the original font installed on any system where you want to open that SVG document.Similar to letter spacing, you can also adjust line spacing in multi-line text objects. Try the Ctrl+Alt+< and Ctrl+Alt+> keys on any paragraph in this tutorial to space it in or out so that the overall height of the text object changes by 1 pixel at the current zoom. As in Selector, pressing Shift with any spacing or kerning shortcut produces 10 times greater effect than without Shift.Editor XMLThe ultimate power tool of Inkscape is the XML editor (Shift+Ctrl+X). It displays the entire XML tree of the document, always reflecting its current state. You can edit your drawing and watch the corresponding changes in the XML tree. Moreover, you can edit any text, element, or attribute nodes in the XML editor and see the result on your canvas. This is the best tool imaginable for learning SVG interactively, and it allows you to do tricks that would be impossible with regular editing tools.ConclusãoEste tutorial mostra apenas uma pequena parte do que o Inkscape é capaz.
