I'm currently creating a program that takes an input GIF, places text on it, and outputs it as a new GIF using the ImageMagick library. My program is perfectly operational when the output GIF is saved somewhere on the computer first and then displayed in a PictureBox by grabbing it from that directory, but is there a way to skip writing it onto disk and instead place the output GIF directly into a PictureBox after it is programmatically created?
I started by trying to have displayPicturebox directly display the ImageMagick collection variable (which theoretically is my GIF already assembled), but it wouldn't let me implicitly convert from MagickImageCollection to System.Drawing.Image.
Next I tried putting all my processed frames into a Memory Stream in GIF format and converting the Memory Stream to a Bitmap in order to be accepted by displayPicturebox, but this only displays a still image of the first frame and nothing else.
// Assume 'collection' is a collection of 10 frames to be turned into a GIF.
MagickImageCollection collection = new MagickImageCollection();
var memStream = new MemoryStream();
// Writes all frames onto memStream in GIF format...?
collection.Write(memStream, MagickFormat.Gif);
memStream.Position = 0;
var bitmap = Image.FromStream(memStream);
displayPicturebox.Image = new Bitmap(bitmap);
I have read that it is possible for Bitmaps to be animated, so I was wondering if there was a way to make this work or if the GIF has to be saved on disk first.
it seems you just need to assign the bitmap to the PictureBox, try this:
displayPicturebox.Image = bitmap;
