Hi,
I'm trying to change the defqult value of the pseudo tag TIFFTAG_ZIPQUALITY. I use TIFFSetField(tif, TIFFTAG_ZIPQUALITY, 50).
It seem to be without effect.
In the following function sp->state = 0... I never call deflateParams.
static int
ZIPVSetField(TIFF* tif, ttag_t tag, va_list ap)
{
ZIPState* sp = ZState(tif);
static const char module[] = "ZIPVSetField";
switch (tag) {
case TIFFTAG_ZIPQUALITY:
sp->zipquality = va_arg(ap, int);
if (tif->tif_mode != O_RDONLY && (sp->state&ZSTATE_INIT)) {
if (deflateParams(&sp->stream,
sp->zipquality, Z_DEFAULT_STRATEGY) != Z_OK) {
TIFFError(module, "%s: zlib error: %s",
tif->tif_name, sp->stream.msg);
return (0);
}
}
return (1);
default:
return (*sp->vsetparent)(tif, tag, ap);
}
/*NOTREACHED*/
}
if someone can show me the way to do it...
thanks
diana
