Method
VipsImagethumbnail_image
Declaration [src]
int
vips_thumbnail_image (
VipsImage* in,
VipsImage** out,
int width,
...
)
Description [src]
Exactly as vips_thumbnail(), but read from an existing image.
This operation
is not able to exploit shrink-on-load features of image load libraries, so
it can be much slower than vips_thumbnail() and produce poorer quality
output. Only use this operation if you really have to.
::: tip “Optional arguments”
* height: gint, target height in pixels
* size: VipsSize, upsize, downsize, both or force
* no_rotate: gboolean, don’t rotate upright using orientation tag
* crop: VipsInteresting, shrink and crop to fill target
* linear: gboolean, perform shrink in linear light
* input_profile: gchararray, fallback input ICC profile
* output_profile: gchararray, output ICC profile
* intent: VipsIntent, rendering intent
* fail_on: VipsFailOn, load error types to fail on
