  • Reading from WMS image - How to maintain a consistent height and width of image with varying bounding boxes without stretching the image..

I have a workspace that inputs property polygons and bounding boxes from an oracle database and it feeds into a WMS feature reader to obtain a raster image. It then overlays property boundary as a redline on top of the image. How do I maintain constant height and width of the image without stretching it?

 

The WMS I am reading from does not have scale hint, nor does it have scale denominator in its implementation.

Hi @generationn00b​,

I created a custom transform to replace a feature's geometry with a bounding box that has a fixed aspect ratio: https://hub.safe.com/publishers/safe-lab/transformers/fixedaspectratioboundingboxreplacer. Send your polygons through this transformer with the desired image size set in the Horizontal and Vertical Components values, then use the resulting bounding boxes in the WMS feature reader.
