How to load the .tfw file when opening a .tif file?

TorbenWiggerich

Hi,

I have a .tif file and an extra .tfw file. How can I load the .tfw file?

From this post I could see how to load the .tif file:

https://community.esri.com/thread/93016?sr=stream&ru=3159

But how can I go further and load the corresponding .tfw file?

In ArcMap it is automatically done, but not in the ArcGIS Runtime SDK for Qt.

It works now

Yes, this was my problem. I didn't undestood that everything is based on one spatial refernce. I changed the SpatialReference now to 4326 and it worked well. (Except that the default map is not shown any more...But this is because it is based on another SpatialReference (3857).)

Thank you very much

the *.tfw contains the spatial information for the *.tif file and it is not loaded separately but used by applications to establish the spatial reference of the image if it is used by the application

So this means it is automatically loaded?

When I have a map000.tif and a map000.tfw, lying in the same directory and I load the map000.tif, than the map000.tfw will be automatically loaded?

But I don't see the .tif loaded in my application. (So with another file having already the information inside the tif it will be shown correctly.)

apparently the thread that you listed suggested that they don't load automatically. Did you follow the advice in the thread?

TorbenWiggerich

Actually I followed the example from this site Raster‌ which was shown in the thread by Eric Bader.

So which advice do you mean? I didn't see any advice there...
