Upscaling resolution question

Josee M

In the SOAP or REST API, there is a boolean upscaleImage option for getInboundFaxAdvanced

The documentation doesn't provide any info on what upscaling provides as far as resolution or dpi.

Is the upscaling to 300 dpi?

We added that option for those that have issues with TIFF images that have asymmetric resolutions. In our case, the only supported resolution that is asymmetric is low resolution (200x100 dpi). So basically, when you enable the upscaleImage option, it will upscale the TIFF image to a symmetric resolution before returning it to the caller. Concretely, this only apply to low resolution TIFF images (200x100 → 200x200), all our other supported resolutions are symmetric.
