I would like to use the pixel values from a raster to proceed with different kind of analysis without converting to vector data. As you can see in the screenshot, in this case is the value from Band 0 (INT32) such as 50.

Hi @felipeverdu1
I believe you can use the transformer RasterCellCoercer and its possible to choose the point geometry.

You can create a point, offset or affine it by values like target_row,target_col. Using of course the raster extents (lower left corner for instance) and then use a PointOnRasterValueExtractor to extract the values at the target location.

You can of course control the point creation any which way you like.
Still, GDAL or PIL (for python) can do pixel-targeting without having to create geometry first.

@gio and @danilo_fme: First of all, thans for your comments. I prefer not to use vector data but raster data since this is more effective and practical in my workflow. It is like in ArcGIS/Python using raster directly.

There is a similar question here: Extract Pixel from Raster
I solved this thing using a RasterExpressionEvaluator. It was my little knowledge of implementing if statements in the expression evaluator what hinder my understanding. Thanks, @danilo_fme
