Alpha Compositing: Blending Two Raster Images

Example showing how to mix the pixels of two images so that one image gradually transforms into the other using alpha band compositing.

Using Attribute Values in the RasterExpressionEvaluator

How to use attribute values inside an expression in the RasterExpressionEvaluator transformer.

Elevation Zoning Scenario

This example combines two types of rasters (a numeric DEM and a color RGB), it also shows how to bring the rasters to the same pixel size, and divide into zones depending on values in the DEM.

Combining Rasters with the RasterExpressionEvaluator

Using the RasterExpressionEvaluator to combine two rasters. This can be done by copying cell values from one raster directly onto another or by creating a semitransparent overlay affect.

Change Detection with the RasterExpressionEvaluator

How to use the RasterExpressionEvaluator for change detection. This example shows how to find what is added, deleted, or stayed the same between two rasters.

Using Conditions with the RasterExpressionEvaluator Transformer

These examples demonstrate how to use conditions in the RasterExpressionEvaluator to isolation and perform operations on specific band values in a raster.

RasterMosaicking with Alpha Compositing

Example of how to work with the RasterMosaicker's alpha compositing option.

Using the RasterTiler

The RasterTiler transformer splits each input raster into a series of tiles by specifying either a tile size (Number of Columns and Number of Rows) or a number of tiles (Number of Horizontal Tile...

Raster To Raster Tutorial Example

The article from FME Raster Tutorial shows a simple raster to raster conversion

Raster Clipping

The article illustrates how to use vector clippers to clip rasters.

Raster Resampling

The article explains what raster resampling is and how FME performs this operation.

Understanding Raster Images

Overview and information on raster images.

RasterSubsetter Example

The article shows how to use RasterSubsetter transformer.

Creating Bar Charts with WebCharter Transformer

The WebCharter transformer lets you create bar charts from different datasets.

Raster Pyramiding Example

The article shows how to make a raster pyramid - a series of reduced resolution representations of the source raster

Workspace Showing Raster to 3D example

This example shows how to convert a raster image to 3D vector features.

Setting NODATA Values with the RasterMosaicker Transformer

Setting the NODATA value with a RasterMosaicker transformer allows for settings which make the black color around raster maps transparent.

Steganography with FME

An example of comparing raster images using the RasterExpressionEvaluator to compare pixel values.

Custom transformer BrightnessContrastAdjuster

This simple custom transformer adjusts the brightness and contrast of an image.

Raster Mask and LOD (Level of Detail) for KML Output

An example of using a raster mask and setting level of detail for raster images being output to Google Earth KML.
