Which method I need to load a image via a data url?
The image data ist stored in a database, as string.
Example: "data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAlgAAAEsCAYAAAAfPc2WAAAS2ElEQVR4Xu3dMYusZwEF4BOsbNSAnYWo6TWE" and lot more
Thank you
Eric

I solved it by some extra code:
Code: Select all
var base64Data = Regex.Match(data, @"data:image/(?<type>.+?),(?<data>.+)").Groups["data"].Value;
var binData = Convert.FromBase64String(base64Data);
GdPictureImaging image = new GdPictureImaging();
var imageId = image.CreateGdPictureImageFromByteArray(binData);

I think so, I use it on Windows, written in C#.
But only basic functions are used, so it should work everywhere. Split up the data url to get the plain data without the header, convert it from base64 to binary, load it into GDPicture
