Vipsjp2kload
Declaration [src]
int
vips_jp2kload (
const char* filename,
VipsImage** out,
...
)
Description [src]
Optional arguments:
page: %gint, load this pagefail_on:VipsFailOn, types of read error to fail on
Read a JPEG2000 image. The loader supports 8, 16 and 32-bit int pixel values, signed and unsigned. It supports greyscale, RGB, YCC, CMYK and multispectral colour spaces. It will read any ICC profile on the image.
It will only load images where all channels have the same format.
Use page to set the page to load, where page 0 is the base resolution
image and higher-numbered pages are x2 reductions. Use the metadata item
“n-pages” to find the number of pyramid layers.
Use fail_on to set the type of error that will cause load to fail. By
default, loaders are permissive, that is, #VIPS_FAIL_ON_NONE.
