将功能发送到FME数据检查器以进行显示。
When the workspace run is completed, any features that enter this transformer will be displayed in the FME inspection application. The Inspector also allows you to view the internal FME Feature Store (FFS) data as it is being processed at that particular moment. Depending on the placement of the Inspector, FME will open the Inspector and load the data in a new view.
Inspector应用程序中的功能类型将具有与其相应的检查器变压器相同的名称。
Input Ports
This transformer has a single unnamed input port that accepts any feature.
输出端口
此变压器没有输出端口。
参数
Group By
If any Group By attributes are specified, their values are appended to the Inspector name to create a feature type for display in the Inspector.
Vector Parameters
笔色覆盖
The pen color override takes precedence over theFME_COLOR.attribute on the feature. It has the same effect as settingFME_COLOR.attribute on the feature to the selected override color for the purposes of inspection.
For point cloud features, if the cloud contains color components for each point, the Inspector will use the color specified in the component. In this case, the pen color override will not be used.
If the cloud does not contain color components for each point, the following priority is used when selecting the paint color for each point:
- If there is a Pen Color Override selected, the inspector application will paint all points in the cloud with the selected override.
- If the cloud does not contain color component and a Pen Color Override is not selected, the inspection application will paint all points in the clouds based on theFME_COLOR.attribute on the feature.
- 如果云不包含颜色组件，并且没有笔色覆盖或FME_COLOR.attribute on the feature, the inspection application will use a color ramp based on the z range from blue for the minimum value to red for the maximum value. When the intensity component exists, the intensity value becomes the lightness of the color.
Area Fill Color Override
The Area Fill Color override sets thefme_fill_color用于检查的特征。
面积填充颜色覆盖不适用于任何不需要填充的任何功能，如点云，行功能和点功能。
Raster Parameters
Reduction Type
This parameter offers different methods to speed up the inspection of rasters:
- No Reduction: Rasters will be visualized in full detail.
- Resample: Large rasters will be resampled down to a smaller size. This is useful if only an overview (that is, not full detail) is required for viewing.
- Subset: Only a subset of each raster will be written. This subset is defined by the Subset Start Column, Subset Number of Columns, Subset Start Row, and Subset Number of Rows parameters.
- 仅限边界框：只写入栅格数据的边界框。
子集启动列
适用Reducti当选择子集on Type parameter. These parameters identify the position in the input raster from which the subset will be taken, as well as the size of the subset.
子集列（单元格）
适用Reducti当选择子集on Type parameter. These parameters identify the position in the input raster from which the subset will be taken, as well as the size of the subset.
Subset Start Row
适用Reducti当选择子集on Type parameter. These parameters identify the position in the input raster from which the subset will be taken, as well as the size of the subset.
子集行数（单元格）
适用Reducti当选择子集on Type parameter. These parameters identify the position in the input raster from which the subset will be taken, as well as the size of the subset.
Point Cloud Parameters
稀疏类型
This parameter offers different methods to speed up the visualization of point clouds by removing points from the cloud:
- Every Nth Point (Interval): Keeps every
th point. - Every Nth Point (Maximum Number of Points): Keeps at most
points that are evenly spaced throughout the dataset. - 第一/最后N个点:<最大数量最多of points> points from the start or end of the dataset. This likely will perform faster but produce a less even distribution of points than the Every Nth Point thinning type.
间隔
指定要保留点的频率。例如，2将导致输入云特征的每个其他点将存在于输出点云中。
Maximum Number of Points
Specifies the maximum points in the output point cloud. For example, an amount of 100 will result in points in the input cloud being dropped so the maximum number of points in the output cloud is 100.
Usage Notes
这是一个非常有用的工具进行调试工作空间s. Keep in mind, however, that you are viewing the internal FME data, which may not be the same as the data eventually written to your output dataset. This is because FME does not apply any format-imposed restrictions on the data.
Shortcuts
- 要附加检查员变压器：右键单击选定的读取器功能类型或变压器，然后选择Connect Inspector(s)。
- 单击“检查器”按钮
to place an Inspector transformer in a workspace. - To immediately open the Viewer, right-click on a reader or writer feature type and selectInspect。
to place an Inspector transformer in a workspace.Redirecting Output to an Inspector
在某些情况下，您可能需要检查输出数据，但您不想实际上必须编写数据来执行此操作。例如，在将更新应用于空间数据库的翻译中，您可能希望在实际提出更新之前检查输出。答案是Redirect to FME Data Inspectorsetting.
When this setting is applied, the output from a translation is redirected away from the specified output and sent directly to the FME Data Inspector.
The simplest way to turn on this feature is to selectWriters > Redirect to FME Data Inspectorfrom the Workbench menu bar. This is a toggle setting, meaning that each selection turns the setting on or off.
变压器历史
This transformer was previously named the Visualizer.

Editing Transformer Parameters
Using a set of menu options, transformer parameters can be assigned by referencing other elements in the workspace. More advanced functions, such as an advanced editor and an arithmetic editor, are also available in some transformers. To access a menu of these options, click
beside the applicable parameter. For more information, seeTransformer Parameter Menu Options。
