ggimg's Issues

Images in png, transparent background plotted in black.

Dear, I have a set of images in png with transparent backgroung generated via:
ggsave(filename = "image1.png",plot = my_ggplot,width = 4, height = 4,dpi=150, bg='transparent')

Now when, I use ggimg the transparent background is plotted as balck. I used a code like this
ggplot(df[1:10,],aes(x=.data[[names(df)[1]]], y=.data[[names(df)[2]]]))+ geom_point_img(aes( x = .data[[names(df)[1]]], y = .data[[names(df)[2]]], img = "image1.png" ), size = 1)+ theme_minimal()

There is a way to tell to goem_point_img to cosider transparent background?

Rotate the image

Hi,

I'd like to know how to rotate the image in geom_point_img function. Thanks.
