This example shows how to convert an image to 3D vector features.
The source is the 亚搏在线Safe logo in PNG format:
The output is saved to PDF format (you need the latest version ofAdobe Readerto view the file):
The main steps in the attached workspace are as follows:
Note that this method works well only with simple rasters with well defined color areas.It can work with gradients but the output will be much bigger.For example,a 3D FME logo made from an image of approximately the same size is above 12 megabytes verses 40 kilobytes for this PDF.This method is also not suitable for scanned maps or photos.Images with lossy compressions,such as used in JPEG,also will give bad results.
Viewing and Inspecting Rasters
Creating Rasters and DEMs from Point Clouds
Setting NoData and Adding Alpha Bands to Remove Black Borders
Draping imagery textures on terrain surfaces
Tiling Raster Data with the RasterTiler
Raster to Raster Translation (Geotiff to JPEG) with Reprojection
Creating Point Clouds from 3D Models or Raster Data
Using Conditions with the RasterExpressionEvaluator Transformer
