Field Documentation

◆ dct_method

int gdJpegReadOptions::dct_method

One of the GD_JPEG_DCT_* constants.

◆ ignore_warning

int gdJpegReadOptions::ignore_warning

Non-zero to suppress recoverable JPEG warnings.

◆ scale_denom

unsigned int gdJpegReadOptions::scale_denom

Decode scale denominator.

◆ scale_num

unsigned int gdJpegReadOptions::scale_num

Decode scale numerator. When build against libjpeg-turbo, the library handles the scaling internally. With libjpeg, the available closed scaling factors are handled by the library, and GD handles the requested scaling then.
