Question
resize images stored as blob

I am trying to resize several thousand images that are stored as sde attachments. I am wondering if it is possible to do this without writing the images to disk. I can extract the full sized images to files using the attributefilewriter. Once I have the images extracted it is straight forward to resize them using the rasterresampler. Since I have so many images I would like to avoid writing them to disk before resizing but the output port of the attributefilewriter does not contain raster data so when I conect it to resampler I get an error.

Hi,
I don't think a blob can be resized directly, but it's possible to create a raster data on the memory from the blob, resample it, and create a new blob of the resulting raster, if the blob format is supported by FME.
i.e.
Create a raster data from the source blog with the RasterReplacer.
Resize the raster with the RasterResampler
Extract a blob from the resulting raster with the RasterExtractor.

As a follow up to this. Is it possible to get the rotation of an image attachment to rotate the image before reampling and saving. I’ve tried a few things but can’t get any to work.
