vips_pngload (
const char* filename,
VipsImage** out,
...
)
Description [src]
Optional arguments:
fail_on:VipsFailOn, types of read error to fail onunlimited: %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.
