Constructor
VipsImagewebpload
Declaration [src]
int
vips_webpload (
const char* filename,
VipsImage** out,
...
)
Description [src]
Read a WebP file into a VIPS image.
Use page to select a page to render, numbering from zero.
Use n to select the number of pages to render. The default is 1. Pages are
rendered in a vertical column, with each individual page aligned to the
left. Set to -1 to mean “until the end of the document”. Use vips_grid()
to change page layout.
Use scale to specify a scale-on-load factor. For example, 2.0 to double
the size on load. Animated webp images don’t support shrink-on-load, so a
further resize may be necessary.
The loader supports ICC, EXIF and XMP metadata.
::: tip “Optional arguments”
* page: gint, page (frame) to read
* n: gint, load this many pages
* scale: gdouble, scale by this much on load
