Export Matrix Object as Image File

The matrix object of any data type can be exported as an image file. Before running the following example need to open new a matrix window and choose File: Import: Image... to import an image into the matrix window. Then run the following example to export the matrix object in this project as gray-scale image to the User Files Folder.

#include <image_utils.h>

//export image from matrix
void export_image()
{	
   // get the matrix page in project
   MatrixPage mp = Project.MatrixPages(0);  
   if (!mp)
   {
     out_str("Failed to get the matrix page!\n");
     return;
   }

   // get the matrix layer in the matrix page
   MatrixLayer ml = mp.Layers(0);   
   if (!ml)
   {
     out_str("Get no matrix layer!\n");
     return;
   }

   // get the matrix object in the matrix layer
   MatrixObject mo = ml.MatrixObjects(0);   
   if (!mo)
   {
     out_str("Get no matrix object!\n");
     return;
   }
	
   string strPageName;
   
   // get the matrix page name
   mp.GetName(strPageName);  

   // the exported image type: png
   string strImageType = "png";  

   // path of image
   string strImagePath = GetAppPath(false) + strPageName + "." + strImageType;  

   // the resolution of the image 
   int nDPI = 300;  

   // set the image as grayscale
   bool bGray = true;   
	
   // export matrix object as image
   int nRet = export_Matrix_to_image(strImagePath, strImageType, mo, nDPI, bGray);
	
   if (nRet != 0)
     out_str("Failed to export matrix object as image!\n");
}
