プリントコンポーザ¶

The print composer provides growing layout and printing capabilities. It allows you to add elements such as the QGIS map canvas, text labels, images, legends, scalebars, basic shapes, arrows, attribute tables and HTML frames. You can size, group, align and position each element and adjust the properties to create your layout. The layout can be printed or exported to image formats, Postscript, PDF or to SVG (export to SVG is not working properly with some recent Qt4 versions, you should try and check individual on your system). You can save the layout as template and load it again in another session. Finally, generating several maps based on a template can be done throught the Atlas generator See a list of tools in table_composer_1:

Table Composer 1: プリントコンポーザツール

すべてのプリントコンポーザツールはメニューとツールバーアイコンから利用できます.ツールバーはマウスをツールバーの上に置いた状態で右ボタンで表示、非表示を切り替えることができます.

最初のステップ¶

新しいプリントコンポーザテンプレートを開く¶

Before you start to work with the print composer, you need to load some raster and vector layers in the QGIS map canvas and adapt their properties to suit your own convenience. After everything is rendered and symbolized to your liking, click the ^{New Print Composer} icon in the toolbar or choose File ‣ New Print Composer. You will be prompt to choose a title for the new composer.

プリントコンポーザを利用する¶

Opening the print composer provides you with a blank canvas to which you can add the current QGIS map canvas, text labels, images, legends, scalebars, basic shapes, arrows, attribute tables and HTML frames. Figure_composer_1 shows the initial view of the print composer with an activated Snap to grid mode but before any elements are added.

Figure Composer 1:

../../../_images/print_composer_blank.png

プリントコンポーザ

プリントコンポーザは４つのタブで構成されています。

The Composition tab allows you to set paper size, orientation, the print quality for the output file in dpi and to activate snapping to a grid of a defined resolution. You can also choose the Number of pages your composition will have. Please note, the Snap to grid feature only works, if you define a grid resolution > 0. Furthermore you can also activate the Print as raster checkbox. This means all elements will be rastered before printing or saving as Postscript or PDF.
The Item Properties tab displays the properties for the selected item element. Click the ^{Select/Move item} icon to select an element (e.g. legend, scalebar or label) on the canvas. Then click the Item Properties tab and customize the settings for the selected element.
The Command history tab (hidden by default) displays a history of all changes applied to the print composer layout. With a mouse click it is possible to undo and redo layout steps back and forth to a certain status.
地図生成 タブでは現在のコンポーザーに地図を生成し、そのパラメーターへのアクセスを可能にします。

コンポーザーには複数のエレメントを追加できます. 複数の地図や凡例やスケールバーをプリントコンポーザキャンバスに配置したり,単一か複数のページを構成することもできます. それぞれのエレメントは独自のプロパティを持ち,地図の場合は独自の領域をもてます. 任意のエレメントをコンポーザキャンバスから削除したい場合If Delete または Backspace キーで可能です.

コンポジションタブ — 一般的なコンポジションのセットアップ¶

コンポジション タブで、コンポジションの全体的な設定を定義できます。

用紙の設定は Presets からの選択か width と height　に独自の値を設定することで指定できます..
Composition can now be parted on several pages. For instance, a first page can show a map canvas and a second page will show the attribute table associated to a layer while a third ons shows a HTML frame linking to your organization website. Set the Number of pages to the desired value.
ページの方向と 出力解像度 を指定して下さい
When checked, the print as raster means all elements will be rasterized before printing or saving as Postscript or PDF.
Snap to grid と Snap to alignements ツールを使うと作業を簡単にすることができます. Dots, Solid lines and Crosses　の3タイプのグリッドを利用できます. spacings, offsets と color を必要に応じて調整できます.
Selection tolerance ではアイテムがグリッドにスナップする最大距離を定義できます.
Snap to alignements shows helping lines when the borders or axis of two items are aligned.

コンポーザーアイテムの一般的なオプション¶

Composer items have a set of common properties you will find on the bottom of the Item Properties tab: Position and size, Frame, Background, Item ID and Rendering (See figure_composer_2)

Figure Composer 2:

../../../_images/print_composer_common_properties.png

共通アイテムプロパティダイアログ

The Position and size dialog lets you define size and position of the frame that contains the item. You can also choose which Reference point will be set at the X and Y coordinates previously defined.
The Frame shows or hides the frame around the label. Click on the [Color] and [Thickness] buttons to adjust those properties.
the Background enables or disables a background color. Click on the [Color...] button to display a dialog where you pick a color ou choose frome a custom setting. Transparency can also be adjusted throught the alpha field.
他のプリントコンポーザアイテムとリレーションシップを作成するために Item ID を利用してください.
レンダリング モードはオプションフィールドで選択できます. Rendering_Mode を参照して下さい .

レンダリングモード¶

QGIS ベクタやラスタレイヤと同じように先進的なレンダリングがコンポーザーアイテムでも行えるようになりました.

Figure Composer 3:

レンダリングモード

Transparency : you can make the underlying item in the composer visible with this tool. Use the slider to adapt the visibility of your item to your needs. You can also make a precise definition of the percentage of visibility in the the menu beside the slider.
Blending mode: you can achieve special rendering effects with these tools that you previously only know from graphics programs. The pixels of your overlaying and underlaying items are mixed through the settings described below.
- Normal: This is the standard blend mode which uses the alpha channel of the top pixel to blend with the Pixel beneath it; the colors aren’t mixed
- Lighten: It selects the maximum of each component from the foreground and background pixels. Be aware that the results tend to be jagged and harsh.
- Screen: Light pixels from the source are painted over the destination, while dark pixels are not. This mode is most useful for mixing the texture of one layer with another layer. E.g. you can use a hillshade to texture another layer
- Dodge: Dodge will brighten and saturate underlying pixels based on the lightness of the top pixel. So brighter top pixels cause the saturation and brightness of the underlying pixels to increase. This works best if the top pixels aren’t too bright, otherwise the effect is too extreme.
- Addition: This blend mode simply adds pixel values of one layer with the other. In case of values above 1 (in the case of RGB), white is displayed. This mode is suitable for highlighting features.
- Darken: Creates a resultant pixel that retains the smallest components of the foreground and background pixels. Like lighten, the results tend to be jagged and harsh
- Multiply: It multiplies the numbers for each pixel of the top layer with the corresponding pixel for the bottom layer. The results are darker pictures.
- Burn: Darker colors in the top layer causes the underlying layers to darken. Can be used to tweak and colorise underlying layers.
- Overlay: Combines multiply and screen blending modes. In the resulting picture light parts of the picture become lighter and dark parts become darker.
- Soft light: Very similar to overlay, but instead of using multiply/screen it uses color burn/dodge. This one is supposed to emulate shining a soft light onto an image.
- Hard light: Hard light is very similar to the overlay mode. It’s supposed to emulate projecting a very intense light onto an image.
- Difference: Difference subtracts the top pixel from the bottom pixel or the other way round, to always get a positive value. Blending with black produces no change, as values for all colors are 0.
- Subtract: This blend mode simply subtracts pixel values of one layer with the other. In case of negative values, black is displayed.

地図の生成¶

プリントコンポーザーは自動的に地図帳を作成する一般的な機能を含みます。そのコンセプでトは、ジオメトリとフィールドを含むカバレッジレイヤを使用します。カバレッジレイヤの各ジオメトリについて、現在のジオメトリを強調するためにキャンバスマップの内容が移動する場所に生成します。。このジオメトリに関連するフィールドは、テキスト·ラベル内で使用することができます。

There can only be one atlas map by print composer but this one can contain multiple pages. Every pages will be generated with each feature. To enable the generation of an atlas and access generation parameters, refer to the Atlas generation tab. This tab contains the following widgets (see Figure_composer_29):

Figure Composer 29:

../../../_images/print_composer_atlas.png

地図帳作成タブ

A Generate an atlas enables or disables the atlas generation.
A combobox Composer map that allows to choose which map item will be used as the atlas map, i.e. on which map geometries from the coverage layer will be iterated over and displayed.
A combobox Coverage layer that allows to choose the (vector) layer containing the geometries on which to iterate over.
An optional Hidden coverage layer, that if checked, will hide the coverage layer (but not the other ones) during the generation.
An optional Features sorting that, if checked, allows to sort features of the coverage layer. The associated combobox allows to choose which column will be used as the sorting key. Sort order (either ascending or descending) is set by a two-state button that displays an up or a down arrow.
An optional Feature filtering text area that allows to specify an expression for filtering features from the coverage layer. If the expression is not empty, only features that evaluate to True will be selected. The button on the right allows to display the expression builder.
An input box Scaling that allows to select the amount of space added around each geometry within the allocated map. Its value is meaningful only when using the autoscaling mode.
A Fixed scale that allows to toggle between auto-scale and fixed-scale mode. In fixed scale mode, the map will only be translated for each geometry to be centered. In auto-scale mode, the map’s extents are computed in such a way that each geometry will appear in its whole.
出力ファイル名の式 必要に応じて各ジオメトリからファイル名を生成するために使用される式を入力します。これは式に基づいています。このフィールドは複数のファイルにレンダリングするためのみ意味します。
A Single file export when possible that allows to force the generation of a single file if this is possible by the chosen output format (PDF for instance). If this field is checked, the value of the Output filename expression field is meaningless.

In order to adapt labels to the feature the atlas plugin iterates over, use a label with this special notation [%expression using field_name%]. For example, with a city layer with fields CITY_NAME and ZIPCODE, you could insert this :

“[% ‘The area of ‘ || upper(CITY_NAME) || ‘,’ || ZIPCODE || ‘ is ‘ format_number($area/1000000,2) || ‘ km2’ %]“

And that would result in the generated atlas as

“The area of PARIS,75001 is 1.94 km2”.

生成¶

The atlas generation is done when the user asks for a print or an export. The behaviour of these functions will be slightly changed if an atlas map has been selected. For instance, when the user asks for an export to PDF, if an atlas map is defined, the user will be asked for a directory where to save all the generated PDF files (except if the Single file export when possible has been selected).

出力の作成¶

Figure_composer_30 shows the print composer with an example print layout including each type of map element described in the sections above.

Figure Composer 30:

../../../_images/print_composer_complete.png

Print Composer with map view, legend, image, scalebar, coordinates , text and HTML frame added

プリントコンポーザでは多彩な種類の出力形式を利用でき、それぞれの解像度（印刷品質）と紙のサイズを指定できます:

^印刷アイコンを使うと接続されたプリンタかインストールされているプリンタドライバに依存したPostscriptファイルを出力し、レイアウトを印刷することができます。
The ^{Export as image} icon exports the composer canvas in several image formats such as PNG, BPM, TIF, JPG,...
:sup:`PDFとして出力`では定義されているプリントコンポーザをPDFに直接出力します。
:sup:`SVGとして出力`アイコンを使うとプリントコンポーザキャンバスをSVG (Scalable Vector Graphic)として保存できます。

ノート

Currently the SVG output is very basic. This is not a QGIS problem, but a problem of the underlaying Qt library. This will hopefully be sorted out in future versions. Export big raster can sometimes fail, even if there seems to be enough memory. This is also a problem of the underlaying Qt management of raster.

コンポーザの管理¶

With the ^{Save as template} and ^{Load from template} icons you can save the current state of a print composer session as a .qpt template and load the template again in another session.

The ^{Composer Manager} button in the QGIS toolbar and in Composer ‣ Composer Manager allows to add a new composer template, create a new composition based on a previously saved template or to manage already existing templates.

Figure Composer 31:

../../../_images/print_composer_manager.png

デフォルトでコンポーザマネージャはユーザテンプレートを ~/.qgis2/composer_template で探します.

The ^{New Composer} and ^{Duplicate Composer} buttons in the QGIS toolbar and in Composer ‣ New Composer and Composer ‣ Duplicate Composer allow to open a new composer dialog, or to duplicate an existing composition from a previously created one.

Finally you can save your print composition with the ^{Save Project} button. This is the same feature as in the QGIS main window. All changes will be saved in a QGIS project file.
