Fct_Contour

Update any contour that as been modified. The function use the "m_" variable of the frames to know if the TAG values have been modified.

Syntax

int Fct_Contour_Update(

SliceO_Frame * frame

) ;

Parameters

frame

Pointer to the frame to update.

Return value

This function return 1.

Remarks

Requirements

Header:

sliceO_include.hpp

Library:

sliceO_Structures.lib

Example

Updating the contours in the shell_ctrl.cpp file of the "Shell_TomoVision" module.

int Ctrl_Update( UInt64 flag )

{

...

// --- We changed the TAG image. Only re-compute some contours ---

if ( flag & (UPDATE_USER_3) ) {

// --- get the current window ---

SliceO_Window *Window_Cur = (SliceO_Window *) Fct_Variable_Value( "$WINDOW_CUR" ) ;

// --- compute contour for all active slices ---

if ( Iterator_Init( ITERATOR_2, "3D Shell: Ctrl_Update" ) )

while( SliceO_Frame *frame = (SliceO_Frame *) Iterator_Class( ITERATOR_2, CLASS_ID_FRAME, Window_Cur, ITER_FLAG_SELECT ) ) {

// --- if this slice is untouched, skip it ---

if ( ! frame->Flag_Get_Bit( CLASS_MODE_THIS, CLASS_MODE_NONE, CLASS_FLAG_CONTOUR ) )

continue ;

Fct_Contour_Update( frame ) ;

}

Iterator_End( ITERATOR_2 ) ;

Fct_Redraw( REDRAW_ALL_3D ) ;

}

...
