Instance methods
Methods inherited from VipsTarget (10)
vips_target_end
Call this at the end of write to make the target do any cleaning up. You can call it many times.
vips_target_putc
Write a single character ch to target. See the macro VIPS_TARGET_PUTC()
for a faster way to do this.
vips_target_read
Read up to length bytes from target and store the bytes in buffer.
Return the number of bytes actually read. If all bytes have been read from
the file, return 0.
vips_target_seek
Seek the target. This behaves exactly as lseek().
vips_target_steal
Memory targets only (see vips_target_new_to_memory()). Steal all data
written to the target so far, and call vips_target_end().
vips_target_steal_text
As vips_target_steal(), but return a null-terminated string.
vips_target_write
Write length bytes from data to the output.
vips_target_write_amp
Write str to target, but escape stuff that xml hates in text. Our
argument string is utf-8.
vips_target_writef
Format the string and write to target.
vips_target_writes
Write a null-terminated string to target.

Signals
Vips.TargetCustom::end
This signal is emitted at the end of write. The target should do any finishing necessary.
Vips.TargetCustom::seek
This signal is emitted to seek the target. The handler should change the target position appropriately.
Signals inherited from VipsObject (4)
VipsObject::close
The ::close signal is emitted once during object close. The object is dying and may not work.
VipsObject::postbuild
The ::postbuild signal is emitted once just after successful object construction. Return non-zero to cause object construction to fail.
VipsObject::postclose
The ::postclose signal is emitted once after object close. The object pointer is still valid, but nothing else.
VipsObject::preclose
The ::preclose signal is emitted once just before object close starts. The object is still alive.
Signals inherited from GObject (1)
GObject::notify
The notify signal is emitted on an object when one of its properties has its value set through g_object_set_property(), g_object_set(), et al.
