Tutorial | Básico
Este tutorial demonstra o funcionamento básico do Inkscape. É um documento normal do Inkscape que se pode ver, editar, copiar ou gravar alterações.
The Basic Tutorial covers canvas navigation, managing documents, shape tool basics, selection techniques, transforming objects with selector, grouping, setting fill and stroke, alignment, and z-order. For more advanced topics, check out the other tutorials in the Help menu.
Deslocar a área de visualização
There are many ways to pan (scroll) the document canvas. Try Ctrl+arrow keys to scroll by keyboard. (Try this now to scroll this document down.) You can also drag the canvas by the middle mouse button. Or, you can use the scrollbars (press Ctrl+B to show or hide them). The wheel on your mouse also works for scrolling vertically; press Shift with the wheel to scroll horizontally.
Aumentar e diminuir a vista
The easiest way to zoom is by pressing - and + (or =) keys. You can also use Ctrl+middle click or Ctrl+right click to zoom in, Shift+middle click or Shift+right click to zoom out, or rotate the mouse wheel with Ctrl. Or, you can click in the zoom entry field (in the bottom right corner of the document window), type a precise zoom value in %, and press Enter. We also have the Zoom tool (in the toolbar on left) which lets you to zoom into an area by dragging around it.
Inkscape also keeps a history of the zoom levels you've used in this work session. Press the ` key to go back to the previous zoom, or Shift+` to go forward.
Ferramentas do Inkscape
A barra de ferramentas vertical à esquerda mostra as ferramentas de desenho e edição do Inkscape. Na parte superior da janela, abaixo do menu, localiza-se a Barra de Comandos com botões de comando gerais e a barra Controlos da Ferramenta com controlos que são específicos para cada ferramenta. A Barra de Estado na parte inferior da janela mostra dicas úteis e mensagens enquanto se trabalha no Inkscape.
Many operations are available through keyboard shortcuts. Open Help⇒Keys and Mouse Reference to see the complete reference.
Criar e gerir documentos
To create a new empty document, use File⇒New or press Ctrl+N. To create a new document from one of Inkscape's many templates, use File⇒New from Template… or press Ctrl+Alt+N
To open an existing SVG document, use File⇒Open (Ctrl+O). To save, use File⇒Save (Ctrl+S), or File⇒Save As (Shift+Ctrl+S) to save under a new name. (Inkscape may still be unstable, so remember to save often!)
O Inkscape usa o formato SVG (Scalable Vector Graphics) nos ficheiros gravados. O SVG é um padrão aberto suportado por muitos programas das artes gráficas. Os ficheiros SVG são baseados no XML e podem ser editados com qualquer editor de textos ou editor de XML (para além do Inkscape). Além do SVG, o Inkscape pode importar e exportar vários outros formatos (EPS, PNG, etc.).
Inkscape opens a separate document window for each document. You can navigate among them using your window manager (e.g. by Alt+Tab), or you can use the Inkscape shortcut, Ctrl+Tab, which will cycle through all open document windows. (Create a new document now and switch between it and this document for practice.) Note: Inkscape treats these windows like tabs in a web browser, this means the Ctrl+Tab shortcut only works with documents running in the same process. If you open multiple files from a file browser or launch more than one Inkscape process from an icon it will not work.
Criar formas geométricas
É hora de fazer algumas formas geométricas! Clique na ferramenta Retângulo na barra de ferramentas esquerda (ou pressione a tecla F4) e clique-e-arraste, num novo documento vazio ou aqui mesmo:
Como pode ver, por padrão, os retângulos são azuis, com um traço preto (contorno) e totalmente opaco. Veremos como alterar isto mais à frente. Com outras ferramentas, também se pode criar elipses, estrelas e espirais:
Estas ferramentas são conhecidas como ferramentas de formas geométricas. Cada forma criada mostra uma ou mais alças em forma de diamante; tente arrastá-las para ver como a forma é alterada. A barra de Controlos da Ferramenta é outra maneira de alterar uma forma; estes controlos afetam as formas atualmente selecionadas (ou seja, aquelas que mostram as alças) e definem a configuração padrão que será aplicada a formas criadas posteriormente.
To undo your last action, press Ctrl+Z. (Or, if you change your mind again, you can redo the undone action by Shift+Ctrl+Z.)
Mover, redimensionar, rodar
A ferramenta do Inkscape mais usada é a ferramenta de Selecionar. Clique no primeiro botão (com a seta) na Barra de Ferramentas da esquerda vertical, ou pressione a tecla F1 ou a Barra de Espaço. Agora pode selecionar qualquer objeto. Clique no retângulo abaixo.
Verá oito alças de controlo em forma de setas que apareceram ao redor do objeto. Agora pode:
Move the object by dragging it. (Press Ctrl to restrict movement to horizontal and vertical.)
Scale the object by dragging any handle. (Press Ctrl to preserve the original height/width ratio.)
Agora clique no retângulo novamente. As alças mudam. Agora pode:
Rotate the object by dragging corner handles. (Press Ctrl to restrict rotation to 15 degree steps. Drag the cross mark to position the center of rotation.)
Skew (shear) the object by dragging non-corner handles. (Press Ctrl to restrict skewing to 15 degree steps.)
Com a Ferramenta de Selecionar, também pode usar os campos numéricos na barra de Controles da Ferramenta (logo acima da área de desenho) para configurar os valores exatos para as coordenadas (X e Y) e tamanho (L e A) da seleção.
Transformar com as teclas
Uma das características do Inkscape que o diferencia da maioria dos outros editores vetoriais é sua ênfase na acessibilidade através do teclado. Dificilmente existe algum comando ou ação que seja impossível de realizar a partir do teclado e transformar objetos não é exceção.
You can use the keyboard to move (arrow keys), scale (< and > keys), and rotate ([ and ] keys) objects. Default moves and scales are by 2 px; with Shift, you move by 10 times that. Ctrl+> and Ctrl+< scale up or down to 200% or 50% of the original, respectively. Default rotates are by 15 degrees; with Ctrl, you rotate by 90 degrees.
However, perhaps the most useful are pixel-sizetransformations, invoked by using Alt with the transform keys. For example, Alt+arrows will move the selection by 1 pixel at the current zoom (i.e. by 1 screen pixel, not to be confused with the px unit which is an SVG length unit independent of zoom). This means that if you zoom in, one Alt+arrow will result in a smaller absolute movement which will still look like one-pixel nudge on your screen. It is thus possible to position objects with arbitrary precision simply by zooming in or out as needed.
Similarly, Alt+> and Alt+< scale selection so that its visible size changes by one screen pixel, and Alt+[ and Alt+] rotate it so that its farthest-from-center point moves by one screen pixel.
Note: Linux users may not get the expected results with the Alt+arrow and a few other key combinations if their Window Manager catches those key events before they reach the inkscape application. One solution would be to change the WM's configuration accordingly.
Várias seleções
You can select any number of objects simultaneously by Shift+clicking them. Or, you can drag around the objects you need to select; this is called rubberband selection. (Selector creates rubberband when dragging from an empty space; however, if you press Shift before starting to drag, Inkscape will always create the rubberband.) Practice by selecting all three of the shapes below:
Now, use rubberband (by drag or Shift+drag) to select the two ellipses but not the rectangle:
Cada objeto individual dentro de uma seleção mostra um indicador de seleção — por padrão, uma caixa retangular pontilhada. Estes indicadores facilitam a visualização imediata do que está e não está selecionado. Por exemplo, se selecionar tanto as duas elipses quanto o retângulo, sem os indicadores seria difícil adivinhar se as elipses estão ou não selecionadas.
Shift+clicking on a selected object excludes it from the selection. Select all three objects above, then use Shift+click to exclude both ellipses from the selection leaving only the rectangle selected.
Pressing Esc deselects any selected objects. Ctrl+A selects all objects in the current layer (if you did not create layers, this is the same as all objects in the document).
Agrupar
Podem ser combinados vários objetos num grupo. Um grupo comporta-se como um objeto único quando se arrasta ou transforma. Abaixo, os 3 objetos à esquerda estão independentes; os mesmo 3 objetos à direita estão agrupados. Tente arrastar o grupo.
To create a group, you select one or more objects and press Ctrl+G. To ungroup one or more groups, select them and press Ctrl+U. Groups themselves may be grouped, just like any other objects; such recursive groups may go down to arbitrary depth. However, Ctrl+U only ungroups the topmost level of grouping in a selection; you'll need to press Ctrl+U repeatedly if you want to completely ungroup a deep group-in-group.
You don't necessarily have to ungroup, however, if you want to edit an object within a group. Just Ctrl+click that object and it will be selected and editable alone, or Shift+Ctrl+click several objects (inside or outside any groups) for multiple selection regardless of grouping. Try to move or transform the individual shapes in the group (above right) without ungrouping it, then deselect and select the group normally to see that it still remains grouped.
Preenchimento e traço
Probably the simplest way to paint an object some color is to select an object, and click a swatch in the palette below the canvas to paint it (change its fill color). Alternatively, you can open the Swatches dialog from the View menu (or press Shift+Ctrl+W), select an object, and click a swatch to paint it (change its fill color).
More powerful is the Fill and Stroke dialog from the Object menu (or press Shift+Ctrl+F). Select the shape below and open the Fill and Stroke dialog.
Verá que o painel Preenchimento e Traço tem três abas: Preenchimento, Pintura do traço e Estilo do traço. A aba Preenchimento permite editar o preenchimento (área interior) dos objetos selecionados. Usando os botões logo abaixo da aba, pode-se escolher os tipos de preenchimento, incluindo nenhum preenchimento (o botão com o X), preenchimento de cor lisa, bem como gradientes lineares ou radiais. Para a forma de cima, está ativado o botão de cor lisa.
Mais abaixo do painel, vê-se uma série de botões com sistemas de cores: RGB, HSL, CMYK, Roda e CMS. Provavelmente o mais prático é o sistema de Roda, onde se pode girar o triângulo para escolher uma cor na roda e depois selecionar um tom dessa cor dentro do triângulo. Todos os sistemas de cor contêm um deslizador para configurar a transparência (canal alfa) dos objetos selecionados.
Sempre que se seleciona um objeto, o sistema de cores é atualizado para mostrar o seu preenchimento e traço atual (quando são selecionados vários objetos, o painel mostra a sua cor média de entre todos os objetos). Faça experiências com estes exemplos:
Usando a aba Pintura do traço, pode-se remover o traço (contorno) do objeto, ou atribuir-lhe qualquer cor ou transparência:
A última aba, Estilo do traço, permite configurar a espessura do traço e outros parâmetros deste:
Finalmente, em vez de uma cor lisa, pode-se usar gradientes para preenchimentos e/ou traços:
When you switch from flat color to gradient, the newly created gradient uses the previous flat color, going from opaque to transparent. Switch to the Gradient tool (Ctrl+F1) to drag the gradient handles — the controls connected by lines that define the direction and length of the gradient. When any of the gradient handles is selected (highlighted blue), the Fill and Stroke dialog sets the color of that handle instead of the color of the entire selected object.
Yet another convenient way to change a color of an object is by using the Dropper tool (F7). Just click anywhere in the drawing with that tool, and the picked color will be assigned to the selected object's fill (Shift+click will assign stroke color).
Duplicar, alinhar, distribuir
One of the most common operations is duplicating an object (Ctrl+D). The duplicate is placed exactly above the original and is selected, so you can drag it away by mouse or by arrow keys. For practice, try to fill the line with copies of this black square:
Chances are, your copies of the square are placed more or less randomly. This is where the Align and Distribute dialog (Shift+Ctrl+A) is useful. Select all the squares (Shift+click or drag a rubberband), open the dialog and press the “Center on horizontal axis” button, then the “Make horizontal gaps between objects equal” button (read the button tooltips). The objects are now neatly aligned and distributed equispacedly. Here are some other alignment and distribution examples:
Ordem de profundidade (Ordem-Z)
The term z-order refers to the stacking order of objects in a drawing, i.e. to which objects are on top and obscure others. The two commands in the Object menu, Raise to Top (the Home key) and Lower to Bottom (the End key), will move your selected objects to the very top or very bottom of the current layer's z-order. Two more commands, Raise (PgUp) and Lower (PgDn), will sink or emerge the selection one step only, i.e. move it past one non-selected object in z-order (only objects that overlap the selection count, based on their respective bounding boxes).
Pratique usando estes comandos alterando a ordem-Z dos objetos presentes abaixo, de forma a que a elipse mais à esquerda fique no topo e a elipse mais à direita fique no fundo:
A very useful selection shortcut is the Tab key. If nothing is selected, it selects the bottommost object; otherwise it selects the object above theselected object(s) in z-order. Shift+Tab works in reverse, starting from the topmost object and proceeding downwards. Since the objects you create are added to the top of the stack, pressing Shift+Tab with nothing selected will conveniently select the object you created last. Practice the Tab and Shift+Tab keys on the stack of ellipses above.
Selecionar um objeto de baixo e arrastá-lo
O que fazer se o objeto que se quer editar está escondido por detrás de outro? Se o objeto por cima for ligeiramente transparente ainda se poderá ver o de baixo, mas clicando sobre ele será selecionado o de cima.
This is what Alt+click is for. First Alt+click selects the top object just like the regular click. However, the next Alt+click at the same point will select the object below the top one; the next one, the object still lower, etc. Thus, several Alt+clicks in a row will cycle, top-to-bottom, through the entire z-order stack of objects at the click point. When the bottom object is reached, next Alt+click will, naturally, again select the topmost object.
[If you are on Linux, you might find that Alt+click does not work properly. Instead, it might be moving the whole Inkscape window. This is because your window manager has reserved Alt+click for a different action. The way to fix this is to find the Window Behavior configuration for your window manager, and either turn it off, or map it to use the Meta key (aka Windows key), so Inkscape and other applications may use the Alt key freely.]
This is nice, but once you selected an under-the-surface object, what can you do with it? You can use keys to transform it, and you can drag the selection handles. However, dragging the object itself will reset the selection to the top object again (this is how click-and-drag is designed to work — it selects the (top) object under cursor first, then drags the selection). To tell Inkscape to drag whatis selected now without selecting anything else, use Alt+drag. This will move the current selection no matter where you drag your mouse.
Practice Alt+click and Alt+drag on the two brown shapes under the green transparent rectangle:
Selecionar objetos similares
Inkscape can select other objects similar to the object currently selected. For example, if you want to select all the blue squares below first select one of the blue squares, and use Edit⇒Select Same⇒Fill Color from the menu. All the objects with a fill color the same shade of blue are now selected.
Para além de se poder selecionar pela mesma cor de preenchimento, pode-se selecionar também objetos similares na cor do traço, estilo do traço, preenchimento e traço, e tipo de objeto.
Conclusão
This concludes the Basic tutorial. There's much more than that to Inkscape, but with the techniques described here, you will already be able to create simple yet useful graphics. For more complicated stuff, go through the Advanced and other tutorials in Help⇒Tutorials.
