Enumeration
VipsForeignFlags
since: 8.0
Description [src]
Some hints about the image loader.
VipsForeignFlags means that the image can be read directly from the
file without needing to be unpacked to a temporary image first.
VipsForeignFlags means that the loader supports lazy reading, but
only top-to-bottom (sequential) access. Formats like PNG can read sets of
scanlines, for example, but only in order.
If neither PARTIAL or SEQUENTIAL is set, the loader only supports whole image read. Setting both PARTIAL and SEQUENTIAL is an error.
VipsForeignFlags means that image pixels are most-significant byte
first. Depending on the native byte order of the host machine, you may
need to swap bytes. See vips_copy().
