Detailed Description

The element JavaScript global object. Add, remove, modify or get information about element nodes in the scene.

With the Element methods, add, remove or retrieve information about the elements in your scene. Each element has an index (0..nbElements-1), an integer id (key of the element in the database), which is unique. They have a name (which is not guaranteed to be unique).

// Rename each element only once.
var o = Object.keys(elements);
for( var idx in o )
{
var elementKey = o[idx];
var elementName = element.getNameById(elementKey);
var newElementName = swapName(elementName);
element.renameById(elementKey, newElementName);
}
function addElement
{
var id = element.add("newDrawing", "BW", 12, "TVG", "SCAN");
}

Member Function Documentation

◆ add

int element::add ( String  name,
String  scanType,
double  fieldChart,
String  fileFormat,
String  vectorize 
)
slot

Creates a new element. Returns the element id of the newly added element if successful, otherwise it returns -1.

Parameters
name: The name of the element.

fieldChart: 12, 16 or 24.
fileFormat: "SCAN", "OPT", "PAL", "SGI", "TGA", "YUV", "OMF" or "PSD".
vectorize: "TVG" or "None".
Returns
Returns the element id of the newly added element if successful, otherwise it returns -1.

◆ completeFolder

String element::completeFolder ( int  id)
slot

Returns the complete element folder. This is normally the element name (unless it has been renamed and the project is not saved) but may include the ".<element id>" in the name if multiple elements share the same name.

Parameters
id: The unique id of the elements.

slot

Returns the number of elements in the scene.

Returns
Returns the number of elements in the scene.

◆ remove

bool element::remove ( int  id,
bool  deleteDiskFile 
)
slot

Removes the given element. Also optionally delete the disk files. This function returns true when successful.

Parameters
id: The unique id of the element.
deleteDiskFile: Optionally, delete the element from the disk.
Returns
Returns true if successful.

◆ renameById

bool element::renameById ( int  id,
String  name 
)
slot

Renames an existing element. The element ID must be provided.

Parameters
id: The unique id of the element.
name: The new name of the element. This name must be unique. This operation will physically rename all the files associated to this element.
Returns
Returns true if successful.

◆ scanType

String element::scanType ( int  id)
slot

Returns a string that is the scan type of the element. The scan type is either: COLOR, GRAY_SCALE or BW.

Parameters
id: The unique id of the element.
Returns
Returns a string that is the scan type of the element.

◆ vectorType

int element::vectorType ( int  id)
slot

This function returns the vector type for the given element. In theory, there is support for multiple types of vector drawing. In practice, only TVG has been implemented. The value 0 : indicates that the element is NOT a vector drawing. It is an IMAGE type. The value 2: indicates that the element is a TVG vector drawing.

Parameters
id: The unique id of the element.
Returns
Returns the vector type for the given element.
