fmeraster
I want to convert JPEG to Geotiff in FME.
I use the following workspace
JPEG reader -> RasterExtractor -> CoordinateSystemSetter -> RasterGeoreferencer (parameter : extents) -> Reprojector -> GEOTIFF writer.
The transformation fails at the RasterGeoreferencer with error
Invalid coordinates. The four coordinates must form a rectangle, which can be rotated
RasterGeoreferencer: A fatal error has occurred. Check the logfile above for details
Any suggestions?
Using FME 2013 beta here
read the CAD [DXF] control the geometry - GeometryCoercer (FMEline) control the geometry - Force 2D (2d line only)
Build the Polygons
Output port AREA
Write Shapefile
See Image - as proof of concept.
Use the CoordinateExtractor transformer. According to the documentation:
Retrieves the value of the x, y, and z coordinate at the specified index into attributes. A negative index can be used to indicate the position relative to the end of the feature (-1 is the last coordinate, -2 the second last, and so on). The index can be entered as an integer, or may be taken from the value of another attribute by selecting the attribute name from the pull-down list. If the index is invalid, then the translation will be terminated.
If the feature was two-dimensional, then the Z attribute will be given the default value specified.
If the feature was a multi-part feature (aggregate), each part’s coordinates are indexed sequentially.

Ok. I think what's going on is that you have the wrong parameters set in RasterGeoreferencer. The below image is WRONG:
What's going on there (and what I guess you're doing) is that I've not specified a square for the coordinates, they're going to make some weird shape. This gives me the same error you're getting.
What you need to do is enter correct, square/rectangular coordinates. So if you had a raster like this:
I'd enter co-ordinates like this:
Although that does turn it upside down which is possibly undesirable, but that's just trial and error. :-) Either way, it is projected now!
Also: I don't think you need the
RasterExtractor(mine works fine without it) unless you want to put the raster into a specific attribute (which you don't).Nor do you need the
Reprojectorbecause what that does is change from one coordinate system to another, but if you've set it withCoordinateSystemSetterandRasterGeoreferencer, then its already set.
