Displaying random GIF images from a specified location

I have been working on my AI for a while now, but i can't seem to get my AI to display a random GIF image into my Picture Box from this location.
C:\Users\scatt\Desktop\Marvel-J.A.R.V.I.S-Personal-Assistant-Winform-C--master\Marvel J.A.R.V.I.S Personal Assistant\Resources\AIPICS\
Example of what's needed.
string[] imagePaths1 = Directory.GetFiles(#"C:\Users\scatt\Desktop\Marvel-J.A.R.V.I.S-Personal-Assistant-Winform-C--master\images", "*.gif", SearchOption.AllDirectories);
But instead of Audio files I need GIF images.
This is a sample of the code I have been using.
case "test":
int image1;
Random randim = new Random();
image1 = randim.Next(0, 4);
switch (image1)
{
case 0:
pictureBox2.Image = Image.FromFile(#"C:\Users\scatt\Desktop\Marvel-J.A.R.V.I.S-Personal-Assistant-Winform-C--master\Marvel J.A.R.V.I.S Personal Assistant\Resources\AIPICS\giphy.gif");
pictureBox2.SizeMode = PictureBoxSizeMode.StretchImage;
pictureBox1.CancelAsync();
break;
case 1:
pictureBox2.Image = Image.FromFile(#"C:\Users\scatt\Desktop\Marvel-J.A.R.V.I.S-Personal-Assistant-Winform-C--master\Marvel J.A.R.V.I.S Personal Assistant\Resources\AIPICS\Party!.gif");
pictureBox2.SizeMode = PictureBoxSizeMode.StretchImage;
pictureBox1.CancelAsync();
break;
case 2:
pictureBox2.Image = Image.FromFile(#"C:\Users\scatt\Desktop\Marvel-J.A.R.V.I.S-Personal-Assistant-Winform-C--master\Marvel J.A.R.V.I.S Personal Assistant\Resources\AIPICS\Staredown.gif");
pictureBox2.SizeMode = PictureBoxSizeMode.StretchImage;
pictureBox1.CancelAsync();
break;
case 3:
pictureBox2.Image = Image.FromFile(#"C:\Users\scatt\Desktop\Marvel-J.A.R.V.I.S-Personal-Assistant-Winform-C--master\Marvel J.A.R.V.I.S Personal Assistant\Resources\AIPICS\tenor.gif");
pictureBox2.SizeMode = PictureBoxSizeMode.StretchImage;
pictureBox1.CancelAsync();
break;
case 4:
pictureBox2.Image = Image.FromFile(#"C:\Users\scatt\Desktop\Marvel-J.A.R.V.I.S-Personal-Assistant-Winform-C--master\Marvel J.A.R.V.I.S Personal Assistant\Resources\AIPICS\idgaf-obama.gif");
pictureBox2.SizeMode = PictureBoxSizeMode.StretchImage;
pictureBox1.CancelAsync();
break;
case 5:
pictureBox2.Image = Image.FromFile(#"C:\Users\scatt\Desktop\Marvel-J.A.R.V.I.S-Personal-Assistant-Winform-C--master\Marvel J.A.R.V.I.S Personal Assistant\Resources\AIPICS\homealone.gif");
pictureBox2.SizeMode = PictureBoxSizeMode.StretchImage;
pictureBox1.CancelAsync();
break;
case 6:
pictureBox2.Image = Image.FromFile(#"C:\Users\scatt\Desktop\Marvel-J.A.R.V.I.S-Personal-Assistant-Winform-C--master\Marvel J.A.R.V.I.S Personal Assistant\Resources\AIPICS\giphy.gif");
pictureBox2.SizeMode = PictureBoxSizeMode.StretchImage;
pictureBox1.CancelAsync();
break;
case 7:
pictureBox2.Image = Image.FromFile(#"C:\Users\scatt\Desktop\Marvel-J.A.R.V.I.S-Personal-Assistant-Winform-C--master\Marvel J.A.R.V.I.S Personal Assistant\Resources\AIPICS\fastsoccer.gif");
pictureBox2.SizeMode = PictureBoxSizeMode.StretchImage;
pictureBox1.CancelAsync();
break;
case 8:
pictureBox2.Image = Image.FromFile(#"C:\Users\scatt\Desktop\Marvel-J.A.R.V.I.S-Personal-Assistant-Winform-C--master\Marvel J.A.R.V.I.S Personal Assistant\Resources\AIPICS\wallstreet.gif");
pictureBox2.SizeMode = PictureBoxSizeMode.StretchImage;
pictureBox1.CancelAsync();
break;
case 9:
pictureBox2.Image = Image.FromFile(#"C:\Users\scatt\Desktop\Marvel-J.A.R.V.I.S-Personal-Assistant-Winform-C--master\Marvel J.A.R.V.I.S Personal Assistant\Resources\AIPICS\DYjbX.gif");
pictureBox2.SizeMode = PictureBoxSizeMode.StretchImage;
pictureBox1.CancelAsync();
break;
}

This code may get you started:
var random = new Random();
var folder = #"C:\Users\scatt\Desktop\Marvel-J.A.R.V.I.S-Personal-Assistant-Winform-C--master\images";
var fileNames = Directory.EnumerateFiles(folder, "*.gif", SearchOption.AllDirectories)
.Select((file, index) => new {file, index})
.ToDictionary(z => z.index, y => y.file);
var randomPic = fileNames[random.Next(0, fileNames.Count)];
pictureBox2.Image = MediaTypeNames.Image.FromFile(Path.Combine(folder, randomPic));
pictureBox2.SizeMode = PictureBoxSizeMode.StretchImage;
pictureBox1.CancelAsync();
The main thing is getting the filenames into a data structure. I use a Dictionary - you could just as easily use a List using:
var random = new Random();
var folder = #"C:\Users\scatt\Desktop\Marvel-J.A.R.V.I.S-Personal-Assistant-Winform-C--master\images";
var fileNames = Directory.EnumerateFiles(folder, "*.gif", SearchOption.AllDirectories).ToList();
var randomPic = fileNames[random.Next(0, fileNames.Count)];
pictureBox2.Image = MediaTypeNames.Image.FromFile(Path.Combine(folder, randomPic));
pictureBox2.SizeMode = PictureBoxSizeMode.StretchImage;
pictureBox1.CancelAsync();
Then randomly choose a filename and populate pictureBox2 with that filename.
You should also strongly consider moving random to be a static field.

you can use the following :-
var basePath =
#"C:\Users\scatt\Desktop\Marvel-J.A.R.V.I.S-Personal-Assistant-Winform-C--master\Marvel J.A.R.V.I.S Personal Assistant\Resources\AIPICS\";
var pics = System.IO.Directory.EnumerateFiles(basePath, "*.gif").ToArray();
var randomPic = pics.OrderBy(p => Guid.NewGuid()).First();
pictureBox2.Image = MediaTypeNames.Image.FromFile(randomPic);
pictureBox2.SizeMode = PictureBoxSizeMode.StretchImage;
pictureBox1.CancelAsync();

Affecting Streamsource from a bitmap to another not working

Rotating a bitmapImage using UriSource works using the following code
private void RotateDocumentImageSourceRight()
{
var biOriginal = (BitmapImage)documentImage.Source;
if (biOriginal == null)
return;
var biRotated = new BitmapImage();
biRotated.BeginInit();
biRotated.UriSource = biOriginal.UriSource;
switch (biOriginal.Rotation)
{
case Rotation.Rotate0:
biRotated.Rotation = Rotation.Rotate270;
break;
case Rotation.Rotate270:
biRotated.Rotation = Rotation.Rotate180;
break;
case Rotation.Rotate180:
biRotated.Rotation = Rotation.Rotate90;
break;
case Rotation.Rotate90:
biRotated.Rotation = Rotation.Rotate0;
break;
default:
break;
}
biRotated.EndInit();
documentImage.Source = biRotated;
}
But when I change the way a bitmapImage is stored to StreamSource it doesn't work and the image disappears
private void RotateDocumentImageSourceRight()
{
...same code...
biRotated.StreamSource= biOriginal.StreamSource;
...same code...
}

You can use a TransformedBitmap, which is used by BitmapImage internally when you specify the Rotation property. It will create a new image, but it will be faster (it won't need to read the stream again).
private void RotateDocumentImageSourceRight()
{
var biOriginal = (BitmapSource)documentImage.Source;
if (biOriginal == null)
return;
var angle = 0.0;
var biRotated = biOriginal as TransformedBitmap;
if (biRotated != null)
{
biOriginal = biRotated.Source;
angle = ((RotateTransform)biRotated.Transform).Angle;
}
angle -= 90;
if (angle < 0) angle += 360;
biRotated = new TransformedBitmap(biOriginal, new RotateTransform(angle));
documentImage.Source = biRotated;
}

Removing EXIF Does not work when using Different Encoders to Choose Format

Im using the following code to fix the orientation of image taking into account the EXIF Orientation Tag
static void FixImageOrientation(Image srce)
{
const int ExifOrientationId = 0x112;
// Read orientation tag
if (!srce.PropertyIdList.Contains(ExifOrientationId)) return;
var prop = srce.GetPropertyItem(ExifOrientationId);
var orient = BitConverter.ToInt16(prop.Value, 0);
// Force value to 1
prop.Value = BitConverter.GetBytes((short)1);
srce.SetPropertyItem(prop);
// Rotate/flip image according to <orient>
switch (orient)
{
case 1:
srce.RotateFlip(RotateFlipType.RotateNoneFlipNone);
break;
case 2:
srce.RotateFlip(RotateFlipType.RotateNoneFlipX);
break;
case 3:
srce.RotateFlip(RotateFlipType.Rotate180FlipNone);
break;
case 4:
srce.RotateFlip( RotateFlipType.Rotate180FlipX);
break;
case 5:
srce.RotateFlip(RotateFlipType.Rotate90FlipX);
break;
case 6:
srce.RotateFlip(RotateFlipType.Rotate90FlipNone);
break;
case 7:
srce.RotateFlip(RotateFlipType.Rotate270FlipX);
break;
case 8:
srce.RotateFlip(RotateFlipType.Rotate270FlipNone);
break;
default:
srce.RotateFlip(RotateFlipType.RotateNoneFlipNone);
break;
}
}
This code removes the EXIF Orientation Tag properly.
And saving the image works is i simply use img.save
But the app provides user the ability to select the format of the image.For that i use the following code
private void saveJpeg(string path, Bitmap img, long quality)
{
EncoderParameter qualityParam = new EncoderParameter(System.Drawing.Imaging.Encoder.Quality, quality);
ImageCodecInfo Codec = this.getEncoderInfo(imgformat);
if (Codec == null)
return;
EncoderParameters encoderParams = new EncoderParameters(1);
encoderParams.Param[0] = qualityParam;
img.Save(path + ext, Codec, encoderParams);
}
public string getimgext(string ccodec)
{
if (ccodec.Equals("image/png"))
{
return ".png";
}
else if (ccodec.Equals("image/jpeg"))
{
return ".jpg";
}
else if (ccodec.Equals("image/tiff"))
{
return ".tif";
}
else if (ccodec.Equals("image/bmp"))
{
return ".bmp";
}
else if (ccodec.Equals("image/gif"))
{
return ".gif";
}
else
{
return null;
}
}
private ImageCodecInfo getEncoderInfo(string mimeType)
{
// Get image codecs for all image formats
ImageCodecInfo[] codecs = ImageCodecInfo.GetImageEncoders();
// Find the correct image codec
for (int i = 0; i < codecs.Length; i++)
if (codecs[i].MimeType == mimeType)
return codecs[i];
return null;
}
When i save the image with SaveJpeg the image gets saved with wrong orientation.What im i doing wrong? Please help.
UPDATE:
I have modified the method so that i dont need to create a new instance of the bitmap as the loop processes many files.But this does not work unless i create a new instance of the bitmap.This process consumes an additional of 10+ seconds of the processing time when compared to the old version.
Im using the code like this
image = (Bitmap)FixImageOrientation(Bitmap.FromFile(path));
Image FixImageOrientation(Image srce)
{
const int ExifOrientationId = 0x112;
// Read orientation tag
if (!srce.PropertyIdList.Contains(ExifOrientationId)) return srce;
var prop = srce.GetPropertyItem(ExifOrientationId);
var orient = BitConverter.ToInt16(prop.Value, 0);
// Force value to 1
prop.Value = BitConverter.GetBytes((short)1);
srce.SetPropertyItem(prop);
// Rotate/flip image according to <orient>
switch (orient)
{
case 1:
srce.RotateFlip(RotateFlipType.RotateNoneFlipNone);
return srce;
case 2:
srce.RotateFlip(RotateFlipType.RotateNoneFlipX);
return srce;
case 3:
srce.RotateFlip(RotateFlipType.Rotate180FlipNone);
return srce;
case 4:
srce.RotateFlip(RotateFlipType.Rotate180FlipX);
return srce;
case 5:
srce.RotateFlip(RotateFlipType.Rotate90FlipX);
return srce;
case 6:
srce.RotateFlip(RotateFlipType.Rotate90FlipNone);
return srce;
case 7:
srce.RotateFlip(RotateFlipType.Rotate270FlipX);
return srce;
case 8:
srce.RotateFlip(RotateFlipType.Rotate270FlipNone);
return srce;
default:
srce.RotateFlip(RotateFlipType.RotateNoneFlipNone);
return srce;
}
}

In one method you have argument of type Image but in other Bitmap. So I'm guessing that you convert source JPEG image to Bitmap before call FixImageOrientation.
This will work:
var jpeg = Image.FromFile("original.jpg");
FixImageOrientation(jpeg);
var bitmap = new Bitmap(jpeg);
saveJpeg("new",bitmap,1);
This won't:
var jpeg = Image.FromFile("original.jpg");
var bitmap = new Bitmap(jpeg);
FixImageOrientation(bitmap);
saveJpeg("new", bitmap, 1);

WIA Setting up page size does not work

Im trying to make an app that can scan documents using C# and WIA. But I have come across a problem when setting up the page size property. When I run the scanning process my app throws an error:
An unhandled exception of type 'System.Runtime.InteropServices.COMException' occurred in DigiKnjiga.exe
Additional information: Exception from HRESULT: 0x80210067
I have tried this using these properties: PageSize(3097), PageWidth(3098) & PageHeight(3099), HorizontalExtent(6151) & VerticalExtent(6152). But setting any of these values throws the before mentioned exception.
Here is the event that starts the scanning process:
private void scanNew_Click(object sender, EventArgs e)
{
if (Scanner.ChosenDevice > 0)
{
Device = deviceManager.DeviceInfos[Scanner.ChosenDevice].Connect();
switch (Scanner.ColorCode)
{
case 0://color
Device.Items[1].Properties["6146"].set_Value(1);
break;
case 1://grayscale
Device.Items[1].Properties["6146"].set_Value(2);
break;
case 2://black and white
Device.Items[1].Properties["6146"].set_Value(4);
break;
}
//(DPI)
Device.Items[1].Properties["6147"].set_Value(Scanner.DPI);
Device.Items[1].Properties["6148"].set_Value(Scanner.DPI);
//brightness
Device.Items[1].Properties["Brightness"].set_Value(Scanner.Brightness);
//contrast
Device.Items[1].Properties["Contrast"].set_Value(Scanner.Contrast);
switch (Scanner.Format)
{
case 0://A3
Device.Items[1].Properties["3097"].set_Value(10);
//Device.Items[1].Properties["6151"].set_Value(11692);
//Device.Items[1].Properties["6152"].set_Value(16535);
break;
case 1://A4
Device.Items[1].Properties["3097"].set_Value(0);
//Device.Items[1].Properties["6156"].set_Value(1);
//Device.Items[1].Properties["3098"].set_Value(8267);
//Device.Items[1].Properties["3099"].set_Value(11692);
////Device.Items[1].Properties["6151"].set_Value(1165 * 2);
////Device.Items[1].Properties["6152"].set_Value(1653 * 2);
////Device.Items[1].Properties["3097"].set_Value("0");
break;
case 2://A5
Device.Items[1].Properties["3097"].set_Value(11);
//Device.Items[1].Properties["6151"].set_Value(1165);
//Device.Items[1].Properties["6152"].set_Value(1653);
break;
}
switch (Scanner.FileType)
{
case 0://JPEG
image = (WIA.ImageFile)Device.Items[1].Transfer(WIA.FormatID.wiaFormatJPEG);
break;
case 1://PNG
image = (WIA.ImageFile)Device.Items[1].Transfer(WIA.FormatID.wiaFormatPNG);
break;
case 2://BMP
image = (WIA.ImageFile)Device.Items[1].Transfer(WIA.FormatID.wiaFormatBMP);
break;
case 3://TIFF
image = (WIA.ImageFile)Device.Items[1].Transfer(WIA.FormatID.wiaFormatTIFF);
break;
}
byte[] imageBytes = (byte[])image.FileData.get_BinaryData();
MemoryStream ms = new MemoryStream(imageBytes);
Image image2 = Image.FromStream(ms);
Bitmap smaller= new Bitmap(image2 , new Size(prikazZbirke.Width, prikazZbirke.Height));
prikazStrani.Size = new System.Drawing.Size(image2 .Width, image2 .Height);
prikazStrani.Location = new Point(0, 0);
prikazStrani.Image = image2 ;
image2 .Save("test.jpg");
}
}
I wonder if anyone knows the solution to the this problem and I thank you in advance for your answers. And at the same time apologise for any spelling mistakes as I am not english.

cahnge switch case as following, it could work(but be sure this property(3097) is supported in your scaner)
switch (Scanner.Format)
{
case 0://A3
Device.Properties["3097"].set_Value(10);
break;
case 1://A4
Device.Properties["3097"].set_Value(0);
break;
case 2://A5
Device.Properties["3097"].set_Value(11);
break;
}

Dynamic random call to image elements to XAML from C#

I have the following code in C#. A function by which I want to highlight one of the nine images at random. The code is as follows,
public void randomize(object sender, MouseButtonEventArgs e)
{
String img = "image";
int random = RandomNumber(10, 18); //Generate Random Number
score.Content = random;
img += random; //append generated number to "image"
//Call function to highlight behind image
ToGold(random);
}
I tried to make the function call ToGold(random) to be able to dynamically refer to one of the images on XAML. But I was not able to make the code work as I intended. So I took a brute force approach as below,
public void ToGold(int Img)
{
Uri gold = new Uri("/Start;component/Images/gold1.png", UriKind.Relative); //Set Uri path of gold image
ImageSource ImgSrc = new BitmapImage(gold); //Define ImageSource and assign
switch(Img)
{
case 10:
{
image10.Source = ImgSrc;
break;
}
case 11:
{
image11.Source = ImgSrc;
break;
}
case 12:
{
image12.Source = ImgSrc;
break;
}
case 13:
{
image13.Source = ImgSrc;
break;
}
case 14:
{
image14.Source = ImgSrc;
break;
}
case 15:
{
image15.Source = ImgSrc;
break;
}
case 16:
{
image16.Source = ImgSrc;
break;
}
case 17:
{
image17.Source = ImgSrc;
break;
}
case 18:
{
image18.Source = ImgSrc;
break;
}
}
}
So my question is how do I make the code efficient by making it dynamic? Can anyone please help me?
NOTE: I have just started studying WPF. So please bear with me.

You can use the FindName method on the window to find an element by its name.
Or you could create an array containing your images in order, i.e. { image0, image1, image2, image3, ... } and then access that array with a random index.
