TIFF image format support

Open mvernacc opened this issue 6 years ago • 4 comments

I would like to be able to open TIFF images with WebPlotDigitizer.

I am using the desktop version. When I try to open a TIFF, it hangs with a "Processing..." message at the top of the screen.

As a workaround, I can convert the TIFFs from our microscope to PNG, but this is an extra step.

Turns out I can open TIFF images if I use WebPlotDigitizer in Microsoft Edge.

I discovered this by reading a wikipedia article referenced in section 2.1 of the manual.

Having TIFF support in the desktop version would still be nice though :)

Interesting, I didn't know MS Edge supported TIFF :)

Right now I rely on whatever browser support is available. The desktop version is based on the Electron project which is just a wrapper around browser technologies. I can look into adding a TIFF decoder at some point.

If tiff is implemented, it would also benefit from multipage selection (like #168) since the TIFF container format supports many images within a single file.

I was just looking around, and I found this library that supports TIFFs using only javascript: https://geotiffjs.github.io/
