FME轉換器基礎概念

這本手冊包含了關於每一個轉換器的摘要資訊，詳細的內容請訪問www.fmeusercentral.com 或查看Workbench協助檔案中的Fme Transformers部分。

This booklet contains a high-level summary of each transformer’s functionality. For detailed information, please visit www.fmeusercentral.com or select FME Transformers from the Workbench Help menu.

什麼是變換器？

What is a Transformer?

變換器是一個用來對要素進行重構的FME Workbench對象。FME包含300多個不同類型的變換器。在Workbench介面中，變換器存放在Transformer Gallery中，並根據功能分類進行合理組織。

A transformer is an FME Workbench object that carries out the restructuring of features. FME contains over 300 different transformers to carry out different types of restructuring. In the Workbench interface, transformers are stored in the Transformer Gallery, and grouped in categories applicable to their associated functionality.

通用變換器參數對話方塊

Common Elements Used in Transformer Parameter Dialogs

在每個變換器的右上方都有一個屬性按鈕。

Every transformer has a Properties button on the right of the transformer.

Properties button

當你點擊屬性按鈕，多數的變換器會顯示一個與當前變換器相關的參數編輯對話方塊，有時在串連變換器時會彈出。大多數變換器的參數編輯對話方塊介面是相似。

When you click the Properties button, most transformers display an Edit Parameters dialog. The content of this dialog depends on the transformer, and sometimes even on connections to the transformer. Most transformers have some common user interface elements, however, and those are described here.

變換器右上方按鈕的顏色代表了參數設定的狀態。

The Properties button at the top-right of the transformer is color-coded to show the status of the settings.

如果按鈕是這樣的顏色，說明你可以使用變換器的現有參數。

If the Properties button is the same color as the transformer, you can use the transformer with its existing parameters.

如果按鈕是黃色，說明變換器包含預設設定，但你還沒有確認，雖然你可以在這個狀態下使用變換器，但是輸出結果卻是不可預測的。

A yellow Properties button indicates that the transformer contains default settings, but you have not yet accepted them. You can use the transformer in this state, but the workspace results may be unpredictable.

紅色的屬性按鈕意味著有一些參數FME不能提供預設參數，你必須自己輸入必填參數後才能使用變換器。

A red Properties button means that there is at least one parameter for which FME cannot supply a default value. You must provide a value in the required field(s) before the transformer can be used.

當你點擊屬性按鈕時，顯示的參數編輯對話方塊類似如下：

When you click a Properties button, the Edit Parameters dialog that appears will usually have some of the common elements shown in this example.
