Function

Vipspngload

Declaration [src]

int
vips_pngload (
  const char* filename,
  VipsImage** out,
  ...
)

Description [src]

Optional arguments:

  • fail_on: VipsFailOn, types of read error to fail on
  • unlimited: %gboolean, remove all denial of service limits

Read a PNG file into a VIPS image. It can read all png images, including 8- and 16-bit images, 1 and 3 channel, with and without an alpha channel.

Any ICC profile is read and attached to the VIPS image. It also supports XMP metadata.

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.

By default, the PNG loader limits the number of text and data chunks to block some denial of service attacks. Set unlimited to disable these limits.
