The IMGOP function, available in the SAS Component Language (SCL), can be used to manipulate and retrieve information about an image file.

The following SCL code shows how the IMGOP function can be used to return the height and width in pixels of a particular image file.

init:                                       
  /* Initialize the command lists */                                            
  cmdid = makelist();                         
  allcmdid=makelist();                        
  rc = insertl(allcmdid,cmdid,-1);            
  
  /* Create the image task, but do not display the image */
  taskid = imginit(allcmdid,'nodisplay');     

  /* Load the image using the task */                                            
  rc=imgop(taskid,'READ','c:\myImageFile.jpg');       
    
  /* Initialize the height and width variables */
  declare num height = 0;                                 
  declare num width = 0;      
   
  /* Retrieve the number of pixels for the image's height and width */
  rc=imgop(taskid,'QUERYN','HEIGHT',height);
  rc=imgop(taskid,'QUERYN','WIDTH',width);    

  /* Write the height and width values to the SAS log */
  put height= width=;
return;
