I'm having trouble placing a raster image onto a map in 100.2 iOS sdk.
This is what I'm currently doing, I make a call to
to download a tif file. I store the extent in the result to construct a world file using the algorithm provided here
raster - How to get values to create world file format? - Geographic Information Systems Stack Exchange .
Afterwards given the tif file and constructed tfw file, I download them to the apps documents library. I then try and load the ads raster with the given constructor
let raster = AGSRaster.init(name: extension: )
I then load the raster however when I check the extent, the spatial reference id, extent values, and center point are all wrong regardless of what I set in the tfw.
How do people go about adding images to maps??
I reviewed https://github.com/Esri/arcgis-runtime-samples-ios/tree/master/arcgis-ios-sdk-samples/Layers/Raster%20layer%20(file)
and noticed that where the Shasta file is included an accompanying aux.xml and .tfw are there. I tried these files in my project to see if they worked, they did. I then tried to load this sample raster with just the tfw which still worked. I know then the problem is in the generation of the tfw, but this image is being generated from a service not arcgis pro, so I need a new way to be able to generate the tfw file .
Does anyone have any suggestions?
