Declaration [src]
int
vips_heifload (
const char* filename,
VipsImage** out,
...
)
Description [src]
Optional arguments:
page: %gint, page (top-level image number) to readn: %gint, load this many pagesthumbnail: %gboolean, fetch thumbnail instead of imageunlimited: %gboolean, remove all denial of service limits
Read a HEIF image file into a VIPS image.
Use page to select a page to render, numbering from zero. If neither n
nor page are set, page defaults to the primary page, otherwise to 0.
Use n to select the number of pages to render. The default is 1. Pages are
rendered in a vertical column. Set to -1 to mean “until the end of the
document”. Use vips_grid() to reorganise pages.
HEIF images have a primary image. The metadata item heif-primary gives
the page number of the primary.
If thumbnail is TRUE, then fetch a stored thumbnail rather than the image.
By default, input image dimensions are limited to 16384x16384.
If unlimited is TRUE, this increases to the maximum of 65535x65535.
The bitdepth of the heic image is recorded in the metadata item
heif-bitdepth.
