Visium coordinates different between SpatialFeaturePlot and seurat_object@image

[nrosewick]

I plotted spatial spots from visium experiment using both SpatialFeaturePlot and using seurat @images coordinates. It seems that the y axis is inverted in brain@images . Is there some explanation ?

Thank you

brain <- SeuratData::LoadData("stxBrain", type = "anterior1")

SpatialFeaturePlot(brain,"nCount_Spatial") |

brain@images$anterior1@coordinates %>%
  bind_cols(brain@meta.data) %>%
     filter(tissue==1) %>%
     mutate(x=imagecol,y=imagerow) %>%
     ggplot(aes(x=x,y=y)) +
     geom_point(aes(col=nCount_Spatial)) +
     scale_color_distiller(palette = "Spectral")
