Hello!
Hopefully I can find some help here. I am building a web portal for users to access and select an image. based on there selection a BLOB is pulled from a SQL Server and the raw data is extracted to render an image.
I am using the magick library to read the image. Everything works locally; however, I can not figure out why it will not work when deploying to the shiny server.
R script:
image_selected <- eventReactive(input$WO_IMAGES_rows_selected, {
image1 <- WONUM_IMAGES()[input$WO_IMAGES_rows_selected,4]
magick::image_read(unlist(image1))
})
image_selected2 <- eventReactive(input$WO_IMAGES_rows_selected, {image_ggplot(image_selected())})
output$WO_IMAGE_RENDER <- renderPlot(image_selected2())
