![]() The tool is easier to use when it's located in the same folder as the images. Save the Jar file to a convenient place to later run the application. Even if this is very unlikely, it's preferable to create a backup of your images before modifying their metadata. But, as any other programs, it may happen to fail during its execution, which may lead to file corruption. The Image Metadata Editor is very stable and reliable. Please, visit Oracle website to install a recent version of Java if you don't already have it installed. You will need Java 7 or higher to be able to run it. The Image Metadata Editor is a Java FX application. How to use the Image Metadata Editor tool If you have a bunch of PNGs to submit then you can convert these to JPEGs using a bulk convertion tool as part of the Image Metadata Editor. Note: The Image Metadata Editor can only attach metadata to JPEG images, not PNG or PDFs. The eAtlas Image Metadata Editor application allows the metadata to be edited for individual images or handled in bulk by using its Export EXIF to CSV and Import EXIF from CSV. The metadata is recorded in the photo files themselves and so this information is maintained when they are copied across computers. This application is intended to be used by eAtlas content administrators and those wishing to submit lots of photos to the eAtlas. ![]() A web page is created for each image using the metadata added to the photo by the Image Metadata Editor. When these images are then uploaded to the eAtlas this metadata is then maintained and displayed on the site. Thank all of u very much.The eAtlas Image Metadata Editor application is a Java program that allows information about the photos, such as title, description, attribution, location, etc., to be recorded and saved in the images themselves. But the none of the properties has a value set. As John said, I created an wpf project WPFApp, I copied your code into the App.g.cs file as followed, public static void Main() The d:\Test.png was created indeed. But that produced an error : "A generic error occurred in GDI+.". Sorry, I already used Image.Save("D:\\PeterTemp\\pic\\d2.jpg"), I forgot mention it. Notice that you can't even make a new PropertyItem. Public static void ListPropertyItems(string Title, Bitmap Bmp)įoreach (PropertyItem PI in Bmp.PropertyItems)Ĭonsole.Write("Id = " + PI.Id.ToString() + " Type = " + PI.Type.ToString() + " ") įor (int I = 0 I < PI.Value.Length I++)Ĭonsole.Write((PI.Value, 16).ToUpper() + " ") PI.Type = 2 //null-terminated ASCII string ListPropertyItems("Form memory stream", Bmp) ![]() Using (MemoryStream MS = new MemoryStream()) This code tries to show what can be done with WF bitmap PropertyItems: using System The code does change the PropertyItem, but changing the PropertyItem produces no effect other than the table change. Changing them after the image has been decoded won't produce any change. Only the JPEG encoder might, and it makes it's own when it saves the image. (It doesn't) Graphics.DrawImage doesn't use the tables. Changing the tables would only produce a change if the JPEG encoder used the tables and the image was saved and reloaded. I don't know what the writer of that code was thinking. He needs to use the BitmapMetadata class. He wants the WIC data, not the JPEG data. Makes a difference on all but empty bitmaps. Have you tried it? It sets the luminance table to the chrominance table. Beware that the Windows 7 version of gdiplus.dll has bugz in the JPEG encoder handling of metadata. jpeg file with some kind of tool that lets you see the metadata. You'd have to save the image, then look at the. Your code snippet does nothing that would let you verify that the properties were correctly.
