This example shows how to load a EMF image from a file and list all of its records.
String dir = "c:\\temp\\";
// Using Aspose.Imaging.Image.Load is a unified way to load all types of images including WMF.
com.aspose.imaging.fileformats.emf.EmfImage emfImage = (com.aspose.imaging.fileformats.emf.EmfImage) com.aspose.imaging.Image.load(dir + "test.emf");
try {
// Cache data to load all records.
emfImage.cacheData();
System.out.println("The total number of records: " + emfImage.getRecords().size());
// The key is a record type, the value is number of records of that type in the WMF image.
java.util.HashMap<Class, Integer> types =
new java.util.HashMap<>();
// Gather statistics
for (Object obj : emfImage.getRecords()) {
com.aspose.imaging.fileformats.emf.emf.records.EmfRecord record = (com.aspose.imaging.fileformats.emf.emf.records.EmfRecord) obj;
Class objType = record.getClass();
if (!types.containsKey(objType)) {
types.put(objType, 1);
} else {
int n = types.get(objType);
types.put(objType, n + 1);
}
}
// Print statistics
System.out.println("Record Type Count");
System.out.println("----------------------------------------------");
for (java.util.Map.Entry<Class, Integer> entry : types.entrySet()) {
String objectType = entry.getKey().getSimpleName();
int numberOfEntrances = entry.getValue();
// Align output with spaces
int alignmentPos = 40;
char[] chars = new char[alignmentPos - objectType.length()];
java.util.Arrays.fill(chars, ' ');
String gap = new String(chars);
System.out.println(objectType + ":" + gap + numberOfEntrances);
}
} finally {
emfImage.dispose();
