プリントコンポーザ
プリントコンポーザはレイアウトと印刷機能をどんどん発展させて提供しています.これによって QGIS マップキャンバス,テキストラベル,イメージ,凡例,スケールバー,基本図形,矢印,属性テーブルとHTMLフレームのようなエレメントを追加することができます. ここではそれぞれのエレメントのサイズ,グループ,配置と位置をプロパティで調整してレイアウトを行います. レイアウトは印刷またはイメージ形式,PostScript,PDFまたはSVGで出力できます (最近の いくつかのQt4 バージョンではSVGへの出力は適切に動作しません; これを動かす場合はあなたのシステムで個別にチェックして下さい). あなたはレイアウトをテンプレートとして保存して別のセッションでロードして使うことができます. 最後に多くの地図をテンプレートにもとづいて作成する作業が地図帳作成機能で行えます. table_composer_1 にあるツールの一覧を参照して下さい:

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
プリントコンポーザで作業を始める前にいくつかのラスタやベクタレイヤを QGIS マップキャンバスにロードしてそれらのプロパティを必要に応じて調整してください.あなたの好みの地図が描画されたらツールバーの New Print Composer アイコンをクリックするか を選択して下さい. 新しいコンポーザのタイトル入力プロンプトが表示されます.
Using Print Composer
Opening the Print Composer provides you with a blank canvas to which you can add
the current QGIS map canvas, text labels, images, legends, scale bars, basic
shapes, arrows, attribute tables and HTML frames. Figure_composer_1 shows the
initial view of the Print Composer before any elements are added.
Figure Composer 1:
The Print Composer provides four tabs:
プリントコンポーザウィンドウの一番下にはステータスバーがあります,そこにはマウスの位置,カレントページ番号とズームレベルを指定できるコンボボックスがあります.
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 Delete または Backspace キーで可能です.
プリントコンポーザオプション
From you can set some options that will be
used as default during your work.
コンポジションデフォルト デフォルトで利用するフォントを指定できます.
With グリッドの外見, グリッドのスタイルを色を指定できます.
Grid defaults ではグリッドの間隔,オフセット,許容値を指定できます. grid: Dots, Solid ラインと Crosses の3タイプのグリッドがあります.
ガイドデフォルト ではガイドの許容値を指定できます.
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。
- You can choose one of the Presets for your paper sheet, or enter your custom width and height.
コンポジションは現在多くのページに分割可能になりました. たとえば最初のページに地図キャンバスを表示して2番目のページにレイヤの属性テーブルを表示して3番目のページにあなたの組織のウェッブサイトにリンクするHTMLフレームを表示することが可能です. Number of pages にお望みの値を指定して下さい. あとページの 向き と 出力解像度 を指定できます. print as raster がチェックされていると印刷の前に全てのエレメントがラスタ化されるか PostScriptかPDFで保存されます.
グリッド では グリッド幅, グリッドオフセット と 許容値 を必要に応じて設定できます.
- In Snap to alignments, you can change the Tolerance, which is the maximum distance below which an item is snapped to smart guides.
グリッドとスマートガイドへのスナップは メニューで有効にできます. このメニューではグリッドとスマートガイドを非表示にすることもできます.
Composer items general options
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:
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:
Layer transparency : このツールによって地図キャンパスにおけるレイヤの可視性を設定できます. このスライダでベクタレイヤの可視性を調整できます. メニューの横にあるスライダを使ってレイヤの表示比率を定義することができます.
レイヤ混合モード: を使うと今までグラフィックプログラムでしか利用できなかったようなすばらしい描画エフェクトを利用することができます.上書きされるレイヤと下に描画されるレイヤのピクセルを下記のような方法で混ぜることができます.
通常: これは標準的な混合モードでトップピクセルのアルファチャンネルを使い下のピクセルと混合します; 色は混合されません
Lighten: この場合フォアグランドとバックグラウンドのピクセルからそれぞれのコンポーネントの最大値を選択します. この結果はギザギザや極端な場合があることに注意して下さい.
Screen: ソースのライトピクセルが書き込み先の上に書き込まれます, 一方ダークピクセルは書き込まれません. このモードはあるレイヤの模様を他のレイヤに混ぜたい場合便利です. (たとえば標高陰影を他のレイヤに重ねる場合利用できます).
覆い焼き: 覆い焼きはトップレベルピクセルの明るさのレベルを基にして下のピクセルの明度をあげ彩度をあげます.ですからトップピクセルが明るくなると下のピクセルの彩度と明度があがります. トップピクセルがそんなに明るくない場合エフェクトは強くかかりうまく動作します.
加算: この混合モードはあるレイヤのピクセル値を単純に他のレイヤに加算します. 値が1以上の場合 (RGBの場合), 白が表示されます. このモードは地物をハイライトさせたい場合に適しています.
暗く:前景色と背景のピクセルの最小の構成要素を保持して生じたピクセルを作成します。明るくのような、結果がギザギザと厳しくなりがちです。
乗算:これは、最下レイヤに対応するピクセルと最上レイヤの各ピクセルの数値を乗算します。結果は暗いピクチャです。
焼き込み:最上レイヤにある暗い色は、下のレイヤが暗くなります。下にあるレイヤを微調整し、色の強調に使用することができます。
オーバーレイ:乗算と網掛けモードを組み合わせたものです。ピクチャのライトパーツの軽量化の結果、明るい部分はより明るくなり、暗い部分がより暗くなります。
ソフトライト:オーバーレイに非常に似ていますが、乗算/覆い焼きの代わりに、色の焼き込み/ダッジを使用しています。この1つは画像の上に柔らかな光が輝いてエミュレートすることになっています。
- Hard light: Hard light is very similar to the overlay mode. It’s supposed to emulate projecting a very intense light onto an image.
差分:差分は、下のピクセルまたは周囲の別のものから上のピクセルを減算し、正の値を取得します。すべてのカラーが0であるため、黒とプレンドしても何も変化しません。
減算: このブレンドモードでは単純にあるレイヤのピクセル値から他のレイヤのピクセル値を引きます. 負の値の数が与えられると黒が表示されます.

アイテムの管理
サイズと位置
Each item inside the Composer can be moved/resized to create a perfect layout.
For both operations the first step is to activate the Select/Move item
tool and to click on the item; you can then move it using the mouse while holding the left button.
If you need to constrain the movements to the horizontal or the vertical axis, just hold
the Shift while moving the mouse.
If you need a better precision, you can move a selected item using the Arrow keys on the keyboard;
if the movement is too slow, you can speed up it by holding Shift.
A selected item will show squares on its boundaries; moving one of them with the mouse, will resize the item
in the corresponding direction.
While resizing, holding Shift will maintain the aspect ratio. Holding Ctrl will resize from
the item center.
The correct position for an item can be obtained using snapping to grid or smart guides. If you need to
disable the snap on the fly just hold Ctrl while moving the mouse.
You can choose multiple items with the Select/Move item button.
Just hold the Shift button and click on all the items you need. You can then resize/move
this group just like a single item.
Once you have found the correct position for an item, you can lock it by clicking with the
right mouse button. Press the same button another time to unlock it. You can also lock/unlock
items using the icons on the toolbar.
To unselect an item, just click on it holding the Shift button.
Inside the menu, you can find actions to select all the items, to clear all selections or
to invert the current selection.
配置
Raising or lowering functionalities for elements are inside the
Raise selected items pull-down menu. Choose an element on the Print Composer
canvas and select the matching functionality to raise or lower the selected
element compared to the other elements (see table_composer_1).
Figure Composer 27:
There are several alignment functionalities available within the
Align selected items pull-down menu (see table_composer_1). To use an
alignment functionality, you first select some elements and then click on the
matching alignment icon. All selected elements will then be aligned within to their common
bounding box.
When moving items on the Composer canvas, alignment helper lines appear when borders, centers or corners are aligned.
アイテムのコピー/切り取りとペースト
The print composer includes actions to use the common Copy/Cut/Paste functionality for the items
in the layout. As usual first you need to select the items using one of the options seen above;
at this point the actions can be found in the menu. When using the Paste action, the elements
will be pasted according to the current mouse position.
地図帳の生成
The Print Composer includes generation functions that allow you to create map books
in an automated way. The concept is to use a coverage layer, which contains
geometries and fields. For each geometry in the coverage layer, a new output
will be generated where the content of some canvas maps will be moved to
highlight the current geometry. Fields associated with this geometry can be used
within text labels.
Every page 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:
You can use multiple map items with the atlas generation; each map will be rendered according
to the coverage features. To enable atlas generation for a specific map item, you need to check
Controlled by Atlas under the item properties of the map item. Once checked, you can set:
- An input box Margin around feature that allows you to select the amount
of space added around each geometry within the allocated map. Its value is
meaningful only when using the auto-scaling mode.
- A Fixed scale that allows you 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 entirety.
ラベル
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, for 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’ %]“
That would result in the generated atlas as
“The area of PARIS,75001 is 1.94 km2”.
プレビュー
Once the atlas settings have been configured and map items selected, you can create a preview of all the pages by
clicking on and using the arrows, in the same menu, to navigate
through all the features.
生成
The atlas generation can be done in different ways. For example, with , you can directly print it. You can also create a PDF using : The user will be asked for a directory for saving all the generated PDF files (except if the Single file export when possible has been selected).
If you need to print just a page of the atlas, simply start the preview function, select the page you need and click on (or create a PDF).
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:
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,...
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。
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。
If you need to export your layout as a georeferenced image (i.e., to load back
inside QGIS), you need to enable this feature under the Composition tab. Check
World file on and choose the map item to use. With this option, the
‘Export as image’ action will create also a world file.
ノート
Currently, the SVG output is very basic. This is not a QGIS problem, but a
problem with the underlying Qt library. This will hopefully be sorted out in
future versions.
Exporting big rasters can sometimes fail, even if there seems to be enough memory.
This is also a problem with the underlying Qt management of rasters.
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 allows you 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:
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 and
allow you 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.
