Image is flipped when using ```image_read()```

[rominasilvera]

Hello. When loading an image using image_read() to then display it, the image is automatically flipped. I need the image to be loaded exactly as it is originally.

Image is vertical

But loaded horizontally

The code:

library(magick)
im <- image_read(path_to_im)
image_ggplot(im)

I cannot reproduce this, for the image that I have it works fine.

Can you share your sessionInfo() and magick_config() ?

Btw you can also display it simply with print(im) or plot(im).

Hi @jeroen , below, I share both sessionInfo() and magick_config():

> print(my.session)

I must say that in a different context, I wouldn't open an issue about this, but my current task requires to treat images differently (in this case, paintings) depending on whether they are horizontal or vertical, therefore, the library loading them wrong gets the data wrong, for example, for the above image:

> target_size <- 255
> im <- image_read(paste0('sample/',im.path))
> image_info(image_scale(im,target_size))
# A tibble: 1 × 7
  format width height colorspace matte filesize density
  <chr>  <int>  <int> <chr>      <lgl>    <int> <chr>  
1 JPEG     255    191 sRGB       FALSE        0 300x300

Both width and height are incorrect. Some images are loaded correctly while others don't.

Does image_orient() help? Like:

im <- image_read(path_to_im) %>% image_orient()
