Vips.Image.set (original) (raw)

Method

Vips Imageset

Declaration [src]


void
vips_image_set (
  VipsImage* image,
  const char* name,
  GValue* value
)

Description [src]

Set a piece of metadata on image. Any old metadata with that name is destroyed. The GValue is copied into the image, so you need to unset the value when you’re done with it.

For example, to set an integer on an image (though you would use the convenience function vips_image_set_int() in practice), you would do:

`GValue value = G_VALUE_INIT;

g_value_init(&value, G_TYPE_INT); g_value_set_int(&value, 42); vips_image_set(image, name, &value); g_value_unset(&value); `

Parameters

name

Type: const char*

The name to give the metadata.

The data is owned by the caller of the method.
The value is a NUL terminated UTF-8 string.

value

Type: GValue

The GValue to copy into the image.
