## Detailed Description

Cropping region.

## Field Documentation

## ◆ h

int tjregion::h

The height of the cropping region.

Setting this to 0 is the equivalent of setting it to the height of the source JPEG image - y.

## ◆ w

int tjregion::w

The width of the cropping region.

Setting this to 0 is the equivalent of setting it to the width of the source JPEG image - x.

## ◆ x

int tjregion::x

The left boundary of the cropping region.

For lossless transformation, this must be evenly divisible by the iMCU width (see tjMCUWidth) of the destination image. For decompression, this must be evenly divisible by the scaled iMCU width of the source image.

## ◆ y

int tjregion::y

The upper boundary of the cropping region.

For lossless transformation, this must be evenly divisible by the iMCU height (see tjMCUHeight) of the destination image.
