Shift-click again to show all layers.A floating selection must be anchored to a new layer or to the last active layer before doing other operations on the image. Click on the "New Layer" or the "Anchor Layer" button in the Layers dialog, or use the menus to do the same.After you enabled "Dynamic Keyboard Shortcuts" in the Preferences dialog, you can reassign shortcut keys. Do so by bringing up the menu, selecting a menu item, and pressing the desired key combination. If "Save Keyboard Shortcuts" is enabled, the key bindings are saved when you exit GIMP.Click and drag on a ruler to place a guide on an image. All dragged selections will snap to the guides. You can remove guides by dragging them off the image with the Move tool.If some of your scanned photos do not look colorful enough, you can easily improve their tonal range with the "Auto" button in the Levels tool (Layer->Colors->Levels). If there are any color casts, you can correct them with the Curves tool (Layer->Colors->Curves).If you stroke a path (Edit->Stroke Path), the paint tools can be used with their current settings. You can use the Paintbrush in gradient mode or even the Eraser or the Smudge tool.If your screen is too cluttered, you can press Tab multiple times in an image window to hide or show the toolbox and other dialogs.Most plug-ins work on the current layer of the current image. In some cases, you will have to merge all layers (Image->Flatten Image) if you want the plug-in to work on the whole image.Not all effects can be applied to all kinds of images. This is indicated by a grayed-out menu-entry. You may need to change the image mode to RGB (Image->Mode->RGB), add an alpha-channel (Layer->Transparency->Add Alpha Channel) or flatten it (Image->Flatten Image).Pressing and holding the Shift key before making a selection allows you to add to the current selection instead of replacing it. Using Ctrl before making a selection subtracts from the current one.To create a circle-shaped selection, hold Shift while doing an ellipse select. To place a circle precisely, drag horizontal and vertical guides tangent to the circle you want to select, place your cursor at the intersection of the guides, and the resulting selection will just touch the guides.When using a drawing tool (Paintbrush, Airbrush, or Pencil), Shift-click will draw a straight line from your last drawing point to your current cursor position. If you also press Ctrl, the line will be constrained to 15 degree angles.You can adjust or move a selection by using Alt-drag. If this makes the window move, your window manager uses the Alt key already. Try pressing Shift at the same time.You can adjust the selection range for fuzzy select by clicking and dragging left and right.You can create and edit complex selections using the Path tool. The Paths dialog allows you to work on multiple paths and to convert them to selections.You can drag a layer from the Layers dialog and drop it onto the toolbox. This will create a new image containing only that layer.You can draw simple squares or circles using Edit->Stroke Selection. It strokes the edge of your current selection. More complex shapes can be drawn using the Path tool or with Filters->Render->Gfig.You can get context-sensitive help for most of the GIMP's features by pressing the F1 key at any time. This also works inside the menus.You can perform many layer operations by right-clicking on the text label of a layer in the Layers dialog.You can press or release the Shift and Ctrl keys while you are making a selection in order to constrain it to a square or a circle, or to have it centered on its starting point.You can save a selection to a channel (Select->Save to Channel) and then modify this channel with any paint tools. Using the buttons in the Channels dialog, you can toggle the visibility of this new channel or convert it to a selection.You can use Alt-Tab to cycle through all layers in an image (if your window manager doesn't trap those keys...).You can use the middle mouse button to pan around the image, if it's larger than its display window.You can use the paint tools to change the selection. Click on the "Quick Mask" button at the bottom left of an image window. Change your selection by painting in the image and click on the button again to convert it back to a normal selection.Project-Id-Version: Report-Msgid-Bugs-To: POT-Creation-Date: 2005-05-14 17:18+0200 PO-Revision-Date: 2004-03-13 17:28+0800 Last-Translator: redarmy Language-Team: zh_CN MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Alt+点击图层对话框中的图层蒙板的预览可以直接查看蒙板。Ctrl+点击图层对话框中的图层蒙板的预览可以切换图层蒙板的效果。使用油漆桶填充工具时Ctrl+点击可以让它使用背景色而不是前景色。使用旋转工具时，Ctrl+拖动可以使得旋转角度限制在 15 度的整倍数。Shift+点击图层对话框的眼睛图标可以隐藏除此以外的其它所有图层。再次Shift+点击显示所有的图层。在对图像进行其它操作之前，必须先把浮动选区固定到当前活动图层或者新的图层。点击图层对话框中的“新建图层”或者“固定图层”按钮，或者使用菜单也可以。当您在首选项对话框中启用了“动态快捷键”以后，您就可以重新分配快捷键了。只要弹出菜单，选择一个菜单项，然后按新的快捷键组合就行了。如果启用了“保存快捷键”，退出 GIMP 时，这些新的快捷键将会被保存下来。点击并拖动标尺可以在图像中放置参考线。所有拖动的选区都会被吸附到参考线上。您可以用移动工具把参考线拖出图像外来删除它们。如果您扫描的一些照片看起来色彩不足，您可以使用色阶工具(图层->颜色->色阶)中的“自动”按钮轻松改进它们的色彩效果。如果有什么颜色损失，您可以用曲线工具(图层->颜色->曲线)把它们纠正回来。勾画路径(编辑->勾画路径)时，您可以按当前的设置使用涂画工具。您可以使用渐变模式的画笔，或者甚至橡皮还有涂抹工具。如果您的屏幕太乱了，您可以在一个图像窗口中多次按Tab键来隐藏或显示工具箱和其它的对话框。大多数插件只能对当前图像的当前图层进行处理。在一些情况下，如果您希望插件对整幅图像进行操作，您将需要合并所有的图层(图层->平整图像)。并非所有的效果都可以应用到所有类型的图像的。这会通过灰色的菜单项表示出来。您也许需要将图像模式改变为 RGB (图像->模式->RGB)、添加一个 alpha 通道(图层->透明->添加 Alpha 通道)或者平整图像(图像->平整图像)。在进行选择以前先按住Shift键允许您添加到当前的选区而不是替代它。如果先按住Ctrl键则从当前的选区中减去。如果需要创建一个圆形选区，可以在进行椭圆选择的时候按住Shift键。需要精确放置一个圆，可以拖动水平和垂直的参考线使之与您想要选择的圆相切，把您的光标放在参考线的相交处，最终的选区就会刚好触到参考线。使用涂画工具(画笔、喷枪或铅笔)时，Shift+点击会从您上次画的点到当前光标位置画一条直线。如果您同时还按着Ctrl键，直线将被限制到 15 的整倍数的角度。可以通过Alt+拖动来调整和改变选区。如果这样做使窗口移位了，说明您的窗口管理器已经使用了Alt键，请同时按住Shift键。您可以点击并左右拖动鼠标来调整模糊选择的选区范围。您可以用路径工具创建和编辑复杂的选区。路径对话框允许您同时操作多个路径以及把它们转换到选区。您可以从图层对话框中拖动一个图层到工具箱中释放。这样会创建一幅只含有那个图层的新图像。使用 编辑->勾画 让您可以沿着当前的选区的边缘进行描画，画出简单的方块或者圆。更复杂的形状可以用 滤镜->绘制->几何图形(GFig) 来画。任何时候您只要按 F1 键就可以得到大多数的 GIMP 特性的上下文相关的帮助。这在菜单里面也可以。您可以在图层对话框中右点图层的文本标签进行许多图层操作。在进行选择的时候，您可以按下或释放Shift和Ctrl键得到一个标准的正方形或圆，或者使它以起始点为中心。您可以将一个选区保存到一个通道(选择->保存到通道)然后用任何的涂画工具修改这个通道。使用通道对话框中的按钮，您可以切换这个新通道的可见状态或者把它转换成一个选区。您可以使用Alt+Tab在一幅图像的各个图层之间循环切换(只要您的窗口管理器没有捕捉那些键……)。如果图像比它的显示窗口大的话，您可以使用鼠标中键来探照整幅图像。您可以使用涂画工具来改变选区。点击图像窗口左下角的“快速蒙板”按钮，在图像上涂画来修改您的选区，然后再次点击按钮把它转换回一个正常选区。
