FME Transformers: 2024.2
Creates an appearance style that can later be applied to a surface (using the AppearanceSetter, for instance).
Coordinate Space Terminology
In order to reduce confusion between the real coordinate space of the surface and the texture coordinate space, this transformer uses "u" and "v" instead of "x" and "y" when referencing the latter. Note that this is also reflected in the parameter names.
For more information on appearance support in FME, see Appearances.
Configuration
Input Ports
Input
A feature that contains either a raster or no geometry. If the input feature contains unsupported geometry, the unsupported geometry will be removed from the feature.
Output Ports
Output
The set options that become attributes on that feature when it is sent out through the Output port.
Parameters
Color
Specifying Colors
Colors may be entered directly or chosen from the color picker via the ellipsis button.
Syntax
Colors can be specified by RGB values or hex codes. RGB values may be either 24-bit or decimal (0 - 1). If the value type is unclear, as in (1,1,1), the 24-bit interpretation is used. Hex codes are accepted with or without a hash sign (#).

Appearance Name |
A name that will help you remember what the appearance is for, such as "castle wall" or "house roof". Note that it does not have to be unique. Attribute name string: fme_appearance_style_name |
|
Diffuse Color |
The most instinctive meaning of the color of an object, the essential color that is revealed under pure white light. It is perceived as the color of the object rather than a reflection of the light. Attribute name string: fme_appearance_style_diffuse_color |
|
Ambient Color |
The color that the object reflects when illuminated by color from the surrounding medium rather than direct light. Attribute name string: fme_appearance_style_ambient_color |
|
Specular Color |
The color of the light reflected from the object through specular reflection (the type of reflection that is characteristic of light reflected from a shiny surface). Attribute name string: fme_appearance_style_specular_color |
|
Emissive Color |
Color of the light that the object is emitting itself. Attribute name string: fme_appearance_style_emissive_color |
|
Shininess |
A value from 0.0 to 1.0 that specifies the shine of specular reflection, with 0.0 being completely dull and 1.0 extremely shiny. Attribute name string: fme_appearance_style_shininess |
|
Alpha |
Specifies the transparency level of the appearance, with 0.0 being completely transparent and 1.0 completely opaque. Attribute name string: fme_appearance_style_alpha |
Texture
|
Texture Center u |
Used to specify the origin of texture coordinate system. It is only used in conjunction with scaling and rotation. Attribute name string: fme_texture_style_center_u |
|
Texture Center v |
Used to specify the origin of texture coordinate system. It is only used in conjunction with scaling and rotation. Attribute name string: fme_texture_style_center_v |
|
Texture Rotation Angle |
Specifies the counter-clockwise rotation angle of the texture in degrees around the texture center (from a line parallel to the u-axis, passing through the texture center). Attribute name string: fme_texture_style_rotation_angle |
|
Texture u Shearing Factor |
Used to specify the amount of shear along the u texture coordinate system axis, relative to the center. Attribute name string: fme_texture_style_u_shearing_factor |
|
Texture v Shearing Factor |
Used to specify the amount of shear along the v texture coordinate system axis, relative to the center. Attribute name string: fme_texture_style_v_shearing_factor |
|
Texture u Scaling Factor |
Used to specify the amount that the texture should be scaled along the u-axis. Attribute name string: fme_texture_style_u_scaling_factor |
|
Texture v Scaling Factor |
Used to specify the amount that the texture should be scaled along the v-axis. Attribute name string: fme_texture_style_v_scaling_factor |
|
Texture u Offset |
Used to specify the offset applied to the texture after all the other transformations are done. Attribute name string: fme_texture_style_u_offset |
|
Texture v Offset |
Used to specify the offset applied to the texture after all the other transformations are done. Attribute name string: fme_texture_style_v_offset |
|
Texture Wrap Style |
Only affects the area outside the 0 to 1 U and V range. Note that not all texture wrapping styles are supported by all output formats, in which case the texture wrapping style will be defaulted to a supported style individual writer. None: means no texture wrapping style is given and behavior outside the 0 to 1 range is unspecified. Repeat in U and V: will tile the texture in both directions. Clamp in U and V: clamps both U and V to the 0 to 1 range and a constant boundary color will fill values outside this range. Clamp in U and Repeat in V: clamps U to the 0 to 1 range and tiles in the V direction. Repeat in U and Clamp in V: clamps V to the 0 to 1 range and tiles in the U direction. Mirror: will mirror the texture in the U and V direction. Border Fill: will use a constant border color to fill values outside the U, V 0 to 1 range. Attribute name string: fme_texture_style_wrap |
|
Texture Border Color |
This parameter is used only with the Border Fill wrapping style, and is only supported by certain formats. It specifies the color to "bleed" into the space surrounding the texture raster. Attribute name string: fme_texture_style_border_color |
Editing Transformer Parameters
Transformer parameters can be set by directly entering values, using expressions, or referencing other elements in the workspace such as attribute values or user parameters. Various editors and context menus are available to assist. To see what is available, click 
beside the applicable parameter.
How to Set Parameter Values
Defining Values
There are several ways to define a value for use in a Transformer. The simplest is to simply type in a value or string, which can include functions of various types such as attribute references, math and string functions, and workspace parameters.
Using the Text Editor
The Text Editor provides a convenient way to construct text strings (including regular expressions) from various data sources, such as attributes, parameters, and constants, where the result is used directly inside a parameter.
Using the Arithmetic Editor
The Arithmetic Editor provides a convenient way to construct math expressions from various data sources, such as attributes, parameters, and feature functions, where the result is used directly inside a parameter.
Conditional Values
Set values depending on one or more test conditions that either pass or fail.
Parameter Condition Definition Dialog
Content
Expressions and strings can include a number of functions, characters, parameters, and more.
When setting values - whether entered directly in a parameter or constructed using one of the editors - strings and expressions containing String, Math, Date/Time or FME Feature Functions will have those functions evaluated. Therefore, the names of these functions (in the form @<function_name>) should not be used as literal string values.
Content Types
| These functions manipulate and format strings. | |
|
Special Characters |
A set of control characters is available in the Text Editor. |
| Math functions are available in both editors. | |
| Date/Time Functions | Date and time functions are available in the Text Editor. |
| These operators are available in the Arithmetic Editor. | |
| These return primarily feature-specific values. | |
| FME and workspace-specific parameters may be used. | |
| Creating and Modifying User Parameters | Create your own editable parameters. |
Dialog Options - Tables
Table Tools
Transformers with table-style parameters have additional tools for populating and manipulating values.
|
Row Reordering
|
Enabled once you have clicked on a row item. Choices include:
|
|
Cut, Copy, and Paste
|
Enabled once you have clicked on a row item. Choices include:
Cut, copy, and paste may be used within a transformer, or between transformers. |
|
Filter
|
Start typing a string, and the matrix will only display rows matching those characters. Searches all columns. This only affects the display of attributes within the transformer - it does not alter which attributes are output. |
|
Import
|
Import populates the table with a set of new attributes read from a dataset. Specific application varies between transformers. |
|
Reset/Refresh
|
Generally resets the table to its initial state, and may provide additional options to remove invalid entries. Behavior varies between transformers. |
Note: Not all tools are available in all transformers.
