Re: Set Image Information

Hello, I'm using the Raster Imaging Pro v15 version (.NET version). I would like to know if it is possible to set custom information on a image saving with Leadtools.

This is an example of what I mean.

With info:


Without info:

If you mean that you want to set the tags for a file (like the Copyright, Model and Make), you can use the WriteComment Method. For more information and to obtain a sample code, please check the help topics below in the .NET help file:
- WriteComment Method
- RasterCommentMetadataType Enumeration

I don't know if they are called tags. I mean the properties inside the rectangle (on the first attached image).

I have tried to add a comment to an image, but nothing appears on the image properties. Am I doing something wrong?

Example code:
--------------------------------
RasterImage myimage= codecs.Load("C:\\test.jpg");
myimage.Comments.Add(new RasterCommentMetadata(RasterCommentMetadataType.Model, Encoding.Default.GetBytes("My model")));
codecs.Save(myimage, "C:\\test_2.jpg", RasterImageFormat.Jpeg, 24, 1, 1, 1, CodecsSavePageMode.Overwrite);
------------

Try to write the comment using the code below:

RasterCommentMetadata comment = new RasterCommentMetadata();
comment.Type = RasterCommentMetadataType.Model;
string artistNameWrite = "My model";
comment.FromAscii(artistNameWrite);
_codecs.WriteComment(@"e:\test_2.jpg", 1, comment);

Using this code I get an "The required JPEG marker is missing" exception.

RasterCodecs.Startup();
RasterCodecs codecs = new RasterCodecs();
RasterImage myimage = codecs.Load("C:\\image.jpg");
RasterCommentMetadata comment = new RasterCommentMetadata();
comment.Type = RasterCommentMetadataType.Model;
string artistNameWrite = "My model";
comment.FromAscii(artistNameWrite);
codecs.Save(myimage, "C:\\image_2.jpg", RasterImageFormat.Jpeg, 24, 1, 1, 1, CodecsSavePageMode.Overwrite);
codecs.WriteComment("C:\\image_2.jpg", 1, comment);                
RasterCodecs.Shutdown();

It seems that the file you are trying to write the EXIF comment to a file that does not support that comment. You need to use EXIF files (Exif Jpeg and Exif TIFF) to be able to use that comment.
