Usage Examples

Image Processing

# Convert format
convert input.png output.jpg

# Resize to 50%
convert input.png -resize 50% output.png

# Optimize PNG
optipng -o7 image.png

# Convert to WebP
cwebp -q 85 input.png -o output.webp

OCR (Image to Text)

# English
tesseract image.png output -l eng

# Greek
tesseract image.png output -l ell

# Multiple languages
tesseract image.png output -l eng+ell
import pytesseract
from PIL import Image

text = pytesseract.image_to_string(
    Image.open('image.png'),
    lang='eng+ell'
)
print(text)

Audio/Video

# Convert video format
ffmpeg -i input.mp4 output.webm

# Extract audio from video
ffmpeg -i video.mp4 -vn audio.mp3

# Create video thumbnail
ffmpeg -i video.mp4 -ss 00:00:05 -frames:v 1 thumb.jpg

# Resize video
ffmpeg -i input.mp4 -vf scale=1280:720 output.mp4

# Convert audio format
ffmpeg -i input.wav output.mp3

# Audio effects with sox
sox input.wav output.wav reverse
sox input.wav output.wav trim 0 30  # First 30 seconds

PDF Processing

# PDF to text
pdftotext document.pdf output.txt

# PDF to images (one per page)
pdftoppm -png document.pdf output

# Compress PDF
gs -sDEVICE=pdfwrite -dPDFSETTINGS=/ebook -o compressed.pdf input.pdf

# Rotate PDF pages
qpdf --rotate=90:1-5 input.pdf output.pdf
from pdf2image import convert_from_path

# Convert PDF to images
images = convert_from_path('document.pdf')
for i, img in enumerate(images):
    img.save(f'page_{i}.png')

Python Image Processing

from PIL import Image
import cv2

# Resize with Pillow
img = Image.open('input.png')
img.thumbnail((800, 600))
img.save('output.jpg')

# OpenCV - read and process
img = cv2.imread('input.png')
gray = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)
cv2.imwrite('gray.png', gray)
