Оперируем с ImageMagick из командной строки

Only shrink larger images using ImageMagick to a ratio

To preserve aspect ratio:

convert -resize 600x600 screen.jpg:

• 1920x1200 => 600x375
• 600x1200 => 300x600
• 150x300 => 300x600
• 300x150 => 600x300

convert -resize 600x600\> screen.jpg:

• 1920x1200 => 600x375
• 600x1200 => 300x600
• 150x300 => 150x300 (is not resized to bigger size)
• 300x150 => 300x150 (is not resized to bigger size)
