What format does “adb screencap /sdcard/screenshot.raw” produce? (without “-p” flag)

Question

I am looking to use adb screencap utility without the -p flag. I imagined output will be dumped in raw format, but doesn\'t look like it. My attempts o

Answer 1

Format:

• 4 bytes as uint32 - width
• 4 bytes as uint32 - height
• 4 bytes as uint32 - pixel format
• (width * heigth * bytespp) bytes as byte array - image data, where bytespp is bytes per pixels and depend on pixel format. Usually bytespp is 4.

Info from source code of screencap.

For your example:

00000000  d0 02 00 00 00 05 00 00  01 00 00 00 1e 1e 1e ff

• d0 02 00 00 - width - uint32 0x000002d0 = 720
• 00 05 00 00 - height - uint32 0x00000500 = 1280
• 01 00 00 00 - pixel format - uint32 0x00000001 = 1 = PixelFormat.RGBA_8888 => bytespp = 4 => RGBA
• 1e 1e 1e ff - first pixel data - R = 0x1e; G = 0x1e; B = 0x1e; A = 0xff;

Pixels with data stored in array of bytes with size 720*1280*4.
