Using Sitefinity's API, I get all images from a given library. Each IContent object of this library is an image, so the content of this IContent object is actually the buffer I need to build an image using System.Drawing.Image class.
string storage = "C:\\Projects\\Sitefinity\\Images\\"; |
var man = new LibraryManager(); |
ILibrary lib = man.GetLibrary("ImageGallery"); |
IList allImages = lib.GetItems(); |
foreach (IContent contentItem in allImages) |
{ |
int i = 0; |
IContent cnt = man.GetContent(contentItem.ID); |
string name = (string)cnt.GetMetaData("Name"); |
string ext = (string)cnt.GetMetaData("Extension"); |
byte[] buffer1 = (byte[])cnt.Content; |
System.Drawing.Image img = System.Drawing.Image.FromStream(new MemoryStream(buffer1)); |
img.Save(storage + name + ext, ImageFormat.Jpeg); |
i++; |
} |
Response.Write(i.ToString() + "-" + "items have been uploaded to:" + storage); |
Here all my images are jpeg, but you can add switch loop for all common formats - jpeg, png, bmp, so that the items will be stored with the same extension to your file system.
