X-Function Execution Options

Variables

Description

This X-Function exports the graph(s) in Origin to various image file(s). It has a graphical user interface (GUI) with previews. In the left panel, there are settings for the functions. In the right, there are two tabs, one is Image, which displays a preview for the exported image, and the other is Graph, which displays a cloned graph page for the source page to be exported.

Supported Formats

Totally 14 image file formats are supported for exporting to image file. These files fall into two categories:

• Raster Formats define a fixed size array of (rows and columns) of colors. These formats take proportionately larger file space for increased detail and do not scale well. Raster file size is a function of resolution and color density. Raster formats are best used when you must reproduce graphs and layout pages with much detail and many colors, and where scalability is not a concern.
• Vector formats contain instructions on how to draw an image and may contain additional information about size and resolution. These formats scale well (within limits), but must be interpreted by a target application, and this is subject to error. File size is proportional to the complexity of the image. Vector formats are best used for graphs and layout pages with little detail and few colors, or for applications where scalability is needed.

The supported formats have been listed for the variable Image Type in the Variables section.

Examples

In this example, we will show how to create the same sub-folder hierarchy according to project folder structure, and export graphs into their own folders named after graph window long name.
Solution for Origin 2017 and later:
Note that predefined path such as <Project Folder><PE Path> was introduced in Origin 2017 to easily export graphs according to project folders in an opj file.

doc -e P
{
  if(page.IsEmbedded==0&&exist(%H)!=11) //Skip over any embedded graphs or Layout windows
    {
      window -a %H; //Activate graph window
      expGraph type:=jpg filename:="<long name>" path:="<Project Folder><PE Path>" theme:=<Original> tr.Margin:=2;
    }
}

Solution for Origin 2016 and later:
Note that string register %@P is only introduced since Origin 2016 SR2 which denotes the full Project Explorer path of the active folder.

doc -e P
{
  if(page.IsEmbedded==0&&exist(%H)!=11) //Skip over any embedded graphs or Layout windows
    {
      window -a %H; //Activate graph window
      string a$=%X; //Get windows path of saved project
      string b$=%@P; //Get graph project path 
      b.Replace("/","\"); //Correct path notation
      i=b.delete(1); 
      string path$=a$+b$; //Concatenate above strings to create export folder path 
      expGraph type:=jpg filename:="<long name>" path:=path$ theme:=<Original> tr.Margin:=2;
    }
}

Solution for Origin 2015 and earlier:

pe_cd /; //move to root directory
string root_folder$;
pe_path path:=root_folder$; //get directory path
//type root_folder$;
int cs=%[root_folder$]; //get path length
cs=cs+2; //add 2 probably due to spaces and similar 
//cs=;
doc -e P //loop over all graph-like objects
{
	if(page.IsEmbedded==0&&exist(%H)!=11)  //Skip over any embedded graphs or Layout windows
	{
		string proj_path$=%X; //Get windows path of saved project;
		//type "the project path is:"+proj_path$;
		window -a %H;	
		string graph_fullPath$;
		pe_path path:=graph_fullPath$; //Get graph project explorer path;
		%A=graph_fullPath$;
		string graph_path$=%[%A,>cs]; //remove the root folder name from path
		//type "the graph path is:"+graph_path$;
		//type "graph title is:"+%H;
		string path$=proj_path$+graph_Path$; //Concatenate above strings to create export folder;
		path.Replace("/","\");
		expGraph type:=jpg filename:="<long name>" path:=path$ theme:=<Original> tr.Margin:=2;
	};
}
