The“eval” signal

voiduser_function (VipsImage *image,gpointer   progress,gpointer   user_data)

The ::eval signal is emitted once per work unit (typically a 128 x128 area of pixels) during image computation.

You can use this signal to update user-interfaces with progressfeedback. Beware of updating too frequently: you will usuallyneed some throttling mechanism.

Usevips_image_set_progress() to turn on progress reporting for animage.

Flags: Run Last

The“invalidate” signal

voiduser_function (VipsImage *image,gpointer   user_data)

The ::invalidate signal is emitted when an image or one of it'supstream data sources has been destructively modified. Seevips_image_invalidate_all().

Flags: Action

The“minimise” signal

voiduser_function (VipsImage *image,gpointer   user_data)

The ::minimise signal is emitted when an image has been asked tominimise memory usage. All non-essential caches are dropped.Seevips_image_minimise_all().

Flags: Action

The“posteval” signal

voiduser_function (VipsImage *image,gpointer   progress,gpointer   user_data)

The ::posteval signal is emitted once at the end of the computationofimage. It's a good place to shut down evaluation feedback.

Usevips_image_set_progress() to turn on progress reporting for animage.

Flags: Run Last

The“preeval” signal

voiduser_function (VipsImage *image,gpointer   progress,gpointer   user_data)

The ::preeval signal is emitted once before computation ofimagestarts. It's a good place to set up evaluation feedback.

Usevips_image_set_progress() to turn on progress reporting for animage.

Flags: Run Last

The“written” signal

voiduser_function (VipsImage *image,gpointer   result,gpointer   user_data)

The ::written signal is emitted just after an image has beenwritten to. It isused by vips to implement things like write to foreign fileformats.

Flags: Action

The“invalidate” signal

voiduser_function (VipsOperation *vipsoperation,gpointer       user_data)
