Tiff Layer with related Contour

Hi support team,
I opened a geotiff dem layer with a Shp contour layer (which is extracted from that geotiff) via code. But on zooming and panning, the geotiff isn’t match with shp. The geotiff moves a little up, down, left or right and some times the two layer are match.
For testing my layers I downloaded an old version of gis editor (ver. 7) and opened that layers together. Every things works good. Is that a known bug?
As I can see, the gis editor opens geotiff and shp layer different from code because the layers in gis editor renders like WMTS layers (every part of page renders like a tile where my layers are just two shp and geotiff layer). But with my sample code, the behavior of rendering this two layers is ordinary like other applications.

Hi Melanie,

Thanks for your information, but unlucky our developer hadn’t succeed to reproduce that

Could you please upload a simple sample with your data, so our developer can look into this.

Thanks,

Don
