Features of magick package
Now we will discuss different types of features are available in the magick package in R.
1. Basic Transformations: Rotating and Flipping
The magick package in R is a powerful tool for performing various image processing tasks, including basic transformations like rotating and flipping images.
# Read the image
img1 <- image_read("New folder/user.jpg")
# Rotate the image
img1_rotated <- image_rotate(img1, 90)
# Flip the image
img1_flipped <- image_flip(img1)
# Flop the image
img1_flopped <- image_flop(img1)
# Save the transformed images
image_write(img1_rotated, path = "New folder/user_rotated_90.jpg")
image_write(img1_flipped, path = "New folder/user_flipped.jpg")
image_write(img1_flopped, path = "New folder/user_flopped.jpg")
Output:
The magick package in R
2. Advanced Transformations: Cropping and Combining
The magick package in R is a powerful tool for performing advanced image processing tasks, including cropping and combining images.
# Read the images
img1 <- image_read("New folder/user.jpg")
img2 <- image_read("New folder/user2.jpg")
# Crop the images
img1_cropped <- image_crop(img1, "200x200+50+50")
img2_cropped <- image_crop(img2, "200x200+50+50")
# Combine images side by side
img_combined <- image_append(c(img1_cropped, img2_cropped))
# Save the combined image
image_write(img_combined, path = "New folder/user_combined.jpg")
Output:
The magick package in R
3. Applying Effects: Blur and Grayscale
The magick package in R is a comprehensive tool for image processing, allowing users to apply various effects to their images.
# Read the images
img1 <- image_read("New folder/user.jpg")
# Apply blur effect
img1_blurred <- image_blur(img1, 10)
# Convert to grayscale
img1_grayscale <- image_convert(img1, colorspace = "gray")
# Save the images with effects
image_write(img1_blurred, path = "New folder/user_blurred.jpg")
image_write(img1_grayscale, path = "New folder/user_grayscale.jpg")
Output:
The magick package in R
4. Adding Borders and Frames
The magick package in R is a versatile tool for image processing, allowing users to add borders and frames to images easily.
# Read the images
img1 <- image_read("New folder/user.jpg")
img2 <- image_read("New folder/user2.jpg")
# Add a border to the images
img1_bordered <- image_border(img1, color = "black", geometry = "20x20")
img2_bordered <- image_border(img2, color = "black", geometry = "20x20")
# Add a frame to the images
img1_framed <- image_frame(img1_bordered, geometry = "10x10", color = "blue")
img2_framed <- image_frame(img2_bordered, geometry = "10x10", color = "blue")
# Save the images with borders and frames
image_write(img1_framed, path = "New folder/user_framed.jpg")
image_write(img2_framed, path = "New folder/user2_framed.jpg")
Output:
The magick package in R
5. Creating Animations and Handling Animated GIFs
The magick package in R is an excellent tool for creating and manipulating images, including animations and animated GIFs.
1. Creating an Animated GIF
To create an animated GIF, we use a series of images and combine them into a single animation. Here’s an example of how to create an animated GIF from two images:
# Define the paths
image_path1 <- "New folder/user.jpg"
image_path2 <- "New folder/user2.jpg"
# Read the images
img1 <- image_read(image_path1)
img2 <- image_read(image_path2)
# Resize the images to a common size
img1_resized <- image_resize(img1, "200x200")
img2_resized <- image_resize(img2, "200x200")
# Combine the images into an animation
img_animation <- image_animate(image_scale(c(img1_resized, img2_resized), "200x200"), fps = 1)
# Save the animation as a GIF
image_write(img_animation, path = "New folder/animation.gif")
Output:
The magick package in R
2. Handling Existing Animated GIFs
We can read an existing animated GIF, manipulate it, and save the result. Here’s an example:
# Read an existing animated GIF
img_gif <- image_read("New folder/animation.gif")
# Split the GIF into individual frames
frames <- image_apply(img_gif, function(frame) {
image_modulate(frame, brightness = 120) # Example transformation: increase brightness
})
# Combine the frames back into an animation
new_gif <- image_animate(frames, fps = 1)
# Save the modified animation
image_write(new_gif, path = "New folder/modified_animation.gif")
Output:
magick package in R
3. Edge Detection
To apply edge detection to an image, we can use the image_edge function. This transformation highlights the edges in an image.
# Read an image
img <- image_read("New folder/user.jpg")
# Apply edge detection
img_edges <- image_edge(img, radius = 1)
# Save the result
image_write(img_edges, path = "New folder/user_edges.jpg")
Output:

The magick package in R
The R magick package is a comprehensive image processing and manipulation tool. It serves as an interface to the ImageMagick library, a robust software suite widely used for handling bitmap images. The package allows R users to perform a variety of tasks on images, such as reading, writing, editing, and transforming them, making it an essential tool for anyone needing advanced image processing capabilities in R Programming Language.
