• Batch resize an entire folder to width=1280 (height auto):

imagesizer batch ./screens ./out --width 1280

Or for a whole folder:

imagesizer appstore ./screens ./out

You will be prompted:

• "iPhone cihaz görseli eklensin mi?" If you choose yes, provide a frame PNG and screen rectangle via flags:

imagesizer appstore input.png ./out \
  --frame-image ./frames/iphone.png \
  --screen-x 100 --screen-y 200 --screen-w 1170 --screen-h 2532
