List of invertGridGeometry() Examples

Examples of invertGridGeometry()

org.geotools.filter.function.RenderingTransformation.invertGridGeometry()
Given a target query and a target grid geometry returns the grid geometry to be used to read the input data of the function involved in rendering. This method will be called only if the input data is a grid coverage or a grid coverage reader @param targetQuery @param gridGeometry @return The transformed query, or null if no inversion is possible/meaningful
org.geotools.process.RenderingProcess.invertGridGeometry()
Given a target query and a target grid geometry returns the grid geometry to be used to read the input data of the process involved in rendering. This method will be called only if the input data is a grid coverage or a grid coverage reader @param targetQuery @param gridGeometry @return The transformed query, or null if no inversion is possible/meaningful

Examples of org.geotools.filter.function.RenderingTransformation.invertGridGeometry()


                // get the desired grid geometry
                GridGeometry2D readGG = gridGeometry;
                if(transformation instanceof RenderingTransformation) {
                    RenderingTransformation tx = (RenderingTransformation) transformation;
                    readGG = (GridGeometry2D) tx.invertGridGeometry(renderingQuery, gridGeometry);
                    // TODO: override the read params and force this grid geometry, or something
                    // similar to this (like passing it as a param to readCoverage
                }
                
                FeatureCollection<?,?> sample = featureSource.getFeatures();

Examples of org.geotools.process.RenderingProcess.invertGridGeometry()

        RenderingProcess process = (RenderingProcess) this.process;
        // evaluate input expressions
        // at this point do not have an object to evaluate them against
        Map<String, Object> inputs = evaluateInputs(null);
        try {
            return process.invertGridGeometry(inputs, targetQuery, targetGridGeometry);
        } catch (ProcessException e) {
            throw new RuntimeException("Failed to invert the grid geometry, error is: "
                    + e.getMessage(), e);
