When I annotate a plot in a custom, non-black, color, and save it as PNG, the image saved does not show the custom colored text, but shows it in black. Please see the following example:
Has anyone encountered this problem and how has it been solved?
using Plots
# ----------------------------------------------------------------------------------------------------
# The following script works no problem at all, until an annotation in non-black custom color saves as black
# -----------------------------------------------------------------------------------------------------
# Generate chart and save as PNG
# -----------------------------------------------------------------------------------------------------
x = rand(100)
y = x .+ rand(100)
plot(x,y, seriestype = :scatter, size = [750,750])
savefig(my_path*"saved_image.png")
# -----------------------------------------------------------------------------------------------------
# Load image for further processing
# -----------------------------------------------------------------------------------------------------
img_path = my_path*"saved_image.png"
image = load(img_path)
# -----------------------------------------------------------------------------------------------------
# Place whitespace left and right of image
# -----------------------------------------------------------------------------------------------------
top = Gray.(ones(100,750))
bottom = left
processed_image = [top;image;bottom]
# -----------------------------------------------------------------------------------------------------
# Place annotation in custom color, but when saved, the annotation is black
# -----------------------------------------------------------------------------------------------------
plot(processed_image)
Plots.annotate!(375, 50, Plots.text("Text in Custom Color - Not Black", RGB(50/255,200/255,218/255), :centre, 12, "Helvetica Bold"))
savefig(my_path*"savedPNG.png")
# -----------------------------------------------------------------------------------------------------
# Loading the image shows a black title ...
