How to read a figure(.png file) and pass it as a binary blob to TERR and visualize in data table or text area in spotfire?
I am tryingto read a picture (png file) and pass it as a binary blob to TERR and visualize in data table in spotfire, I defined a data table (Fig) as the output of my data function in TERR. The problem is that I can not remove header of data table. Also, the size of the figure in data table is very small and I have to adjust it every time I run the data function. Thanks in advance.
# name of picture
tempfilename <- paste0(path,"TestPlot.png")
# Read the resulting png into binaryValue
myConnection <- file(tempfilename,'rb')
binaryValue <- readBin(con=myConnection,what="raw",n=(file.info(tempfilename)$size))
# Generate an output data table, with 1 row, 1 column, with a blob value.
Fig <- data.frame(col1=c(NA))
Fig <- list(binaryValue)
p <- "image/*"
names(p) <- "ContentType"
attr(Fig, "SpotfireDataTableMetaData") <- as.list(p)
