Image Compression¶

imageCompress()¶

Compress image file.

imageCompress(srcPath, destPath, targetByteSize=0, targetWidth=0, targetHeight=0)

Parameters: - srcPath (str): Source image path - destPath (str): Output path - targetByteSize (int): Target file size in bytes (0 = no limit) - targetWidth (int): Target width (0 = original) - targetHeight (int): Target height (0 = original)

Returns: Compressed image path

Screenshot¶

imageReaderGetScreenShot()¶

Capture screen.

imageReaderGetScreenShot(path=None, delayMilliSec=1000)

Parameters: - path (str): Save path - delayMilliSec (int): Delay before capture

Returns: Screenshot path

Video Playback¶

videoPlay()¶

Play video file in fullscreen mode.

videoPlay(path, wait=True)

Parameters: - path (str): Video file path - wait (bool): Wait for playback to complete (default: True)

Barcode Scanning¶

scanBarcodeFromImage()¶

Scan barcode/QR code from image file.

scanBarcodeFromImage(path, compressRatio=0, x=0, y=0, width=0, height=0)

Parameters: - path (str): Image file path - compressRatio (int): Compression ratio (0 = no compression) - x, y, width, height (int): Region to scan (0 = full image)

Returns: Scanned barcode content

Usage Example¶

import androidhelper

droid = androidhelper.Android()

# Take screenshot
ss_path = droid.imageReaderGetScreenShot("/sdcard/screenshot.png", 500).result

# Compress image
compressed = droid.imageCompress(
    "/sdcard/large_photo.jpg",
    "/sdcard/compressed.jpg",
    targetByteSize=102400,  # Target ~100KB
    targetWidth=1920,
    targetHeight=1080
).result
print(f"Saved: {compressed}")

# Play video
video_path = "/sdcard/movie.mp4"
droid.videoPlay(video_path, wait=True)

# Scan barcode from image
result = droid.scanBarcodeFromImage("/sdcard/qr_code.png").result
print(f"Barcode: {result}")
