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.

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.

This must be evenly divisible by the MCU block width (see tjMCUWidth.)

y

int tjregion::y

The upper boundary of the cropping region.

For lossless transformation, this must be evenly divisible by the MCU block height (see tjMCUHeight.)
