Function Documentation

void prev_buffer_lock ( void )

Must be called on access of a prevBuffer->buffer.
Attention: gdk-/X11-mutex must not be locked before locking this
mutex.

void prev_buffer_unlock ( void )

prevType prev_renderdb_register	(	prevType	type,
		renderDbOptsFunc	o_fkt,
		renderDbFreeFunc	f_fkt,
		renderDbCopyFunc	c_fkt,
		renderDbRenderFunc	r_fkt
	)

Register a new render type 'type'.
If 'type' == PREV_NEW use the first unused value and return it.

void prev_renderdb_register_info	(	prevType	type,
		renderDbInfoFunc	i_fkt
	)

Register a function which is called for the "Info Window".

void prev_renderdb_register_vector	(	prevType	type,
		renderDbVectorFunc	v_fkt
	)

Register a function for saving in a vector format.

void** prev_opts_store	(	prevBuffer *	b,
		prevType	type,
		void *	data,
		gboolean	free_data
	)

Store a value associated to type and return its address.
free_data==TRUE: If the window b is freed, data is freed by calling
free().
Used in renderDbOptsFunc() to store the value of the menu entry.

void** prev_opts_get	(	prevBuffer *	b,
		prevType	type
	)

Get the value associated to type stored with prev_opts_store().

void prev_opts_append	(	prevBuffer *	b,
		prevType	type,
			...
	)

Append option widgets to the window specific menu according to
the given types. Last argument must be '-1'.

float prev_get_zoom ( prevBuffer * b )

Return zoom factor to get something of size
b->gc.width x b->gc.height into buffer b.

void prev_chk_save	(	prevBuffer *	b,
		const iwImage *	img
	)

If b->save!=SAVE_NONE:
img!=NULL: Save image img.
img==NULL: Save image b->buffer (size: b->width x b->height).
Attention: prev_buffer_(un)lock is called.

void prev_draw_buffer ( prevBuffer * b )

If b->window is open, display b->buffer.

void prev_pan_zoom	(	prevBuffer *	b,
		int	x,
		int	y,
		float	zoom
	)

If zoom >= 0, change zoom level of the preview.
If x >= 0 or y >= 0 pan the preview to that position.

void prev_signal_connect	(	prevBuffer *	b,
		prevEvent	sigset,
		prevButtonFunc	cback,
		void *	data
	)

Call cback with data as last argument if one of the signals
specified with sigset occured.

void prev_signal_connect2	(	prevBuffer *	b,
		prevEvent	sigset,
		prevSignalFunc	cback,
		void *	data
	)

int prev_get_page ( prevBuffer * b )

Return the page number for the preview settings window. Allows to
create any widgets with the help of the opts_() functions.

void prev_free_window ( prevBuffer * b )

Close preview window b (if necessary), remove it from the CList and
free its memory.

prevBuffer* prev_new_window	(	const char *	title,
		int	width,
		int	height,
		gboolean	gray,
		gboolean	show
	)

Initialise a new preview window (Title: title, size: width x height,
depth: 24bit (gray==FALSE) or 8 Bit (gray==TRUE)).
show == TRUE: The window is shown immediately.
width, heigth < 0 : Default width, height is used.
title contains '.' (a'.'b): Window is shown in the list of windows
under node a with entry b.

iwImage* prev_copy_to_image	(	prevBuffer *	b,
		gboolean	save_full
	)

Copy the content of a preview window into an iceWing image. The
preview window needs to be open (buffer->window != NULL), otherwise
NULL is returned. If save_full the full visible preview window size
is used, otherwise the size of the displayed data is used.
