In today’s modern era, imagery is more popular than ever before. Whether you’re looking to manipulate bands, or clip an image based on a boundary, FME provides users with an abundance of tools to get the job done.

New to imagery in FME? Check out the four custom transformers below, built by our team to help you quickly and more efficiently work with your imagery data in FME.

Save time and effort on workspace development by using these new pre-built tools:

• Use the workspaces as building blocks to create your own prototypes and imagery solutions.
• Cut the number of transformers you need to perform some common imagery tasks, allowing for greater authoring efficiency.
• Experience faster and more consistent implementation of imagery processes.

ImageIdentifier

The ImageIdentifier is designed for use with Ollamas' Llava 7B parameter model, leveraging its API endpoint for image tagging. When a prompt is supplied, Ollama will return string descriptions with the appropriate information. It is intended for use with JPEG and PNG image formats

ImageryHalor

This transformer creates a halo around an image - a gradual blend into the surrounding user-selected color, to create smooth effects and transitions from imagery to a background.

To generate the halo, the transformer creates concentric buffers around the image area. Each buffer receives the same RGB value. Once buffers are rasterized, the transformer copies color values to the alpha band where they will represent the amount of transparency rather than colors. The higher the value, the more transparent a pixel will be moving outward of the project area.

ImageWatermarker

The ImageWatermarker allows you to add a Watermark to images, such as photographs, scanned maps, CAD blueprints, and rasterized PDFs.

This transformer combines two image files (one base image, one watermark image) and overlays the Watermark onto the base image, allowing the user to choose the opaqueness, frequency, angle and scale of the Watermark

ImageColorAdjuster

This transformer assists in Image color adjustments. There are five different choices: Brighten, Color Correction, Greyscale, Inversion, and Gamma Correction.

This transformer takes an image, extracts the image’s bands to determine if the image is a single or multi band image, and performs (an) expression(s).
