Commented Unassigned: VS Debug Disabling when SetTempDirectory was called [1409]

I am use latest Magick.NET-16-AnyCPU library only for loading images in different formats, init code is:
```
StartupPath = Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location);

string TempDirectory = Path.Combine(StartupPath, "Temp");
if (!Directory.Exists(TempDirectory))
Directory.CreateDirectory(TempDirectory);

MagickAnyCPU.CacheDirectory = StartupPath;
MagickAnyCPU.HasSharedCacheDirectory = false;
MagickNET.SetTempDirectory(TempDirectory);

/* int[] A = new int[1]; //VS stop Debug there!!!
A[4] = 0; */
```
as result if program have some exception before "MagickNET.SetTempDirectory(TempDirectory);", debug stopped at line with it, else (after SetTempDirectory) - see attached ScreenShot.
Comments: What happens when you set MagickAnyCPU.CacheDirectory to a location outside the bin directory? Might be possible that .NET 2.0 is not happy with that location.

Created Unassigned: Cannot write proper progressive JPEG [1410]

Using Magick.NET-7.0.3.1-Q8-AnyCPU.zip I'm attempting to take an image and make it a progressive JPEG, however this isn't working as expected.

```
public static void ProcessJpegImageProgressive(Bitmap image, ref MemoryStream stream)
{
using (MagickImage mImage = new MagickImage(image))
{
mImage.Strip();
mImage.Format = MagickFormat.Pjpeg;
mImage.Interlace = Interlace.Plane;
mImage.Quality = 80;
mImage.Depth = 8;
mImage.Settings.SetDefine(MagickFormat.Jpeg, "sampling-factor", "4:2:0");

//mImage.Format = MagickFormat.Pjpeg;
//mImage.CompressionMethod = CompressionMethod.JPEG;
//mImage.SetOption(MagickFormat.Jpeg, "sampling-factor", "4x1,2x1,2x1");

mImage.Write(stream);
}
}
```

Comments: As you can see you are getting an exception in your own code. The "CacheDirectory screenshot" works perfectly but your code is invalid: ``` int[] A = new int[1]; A[100] = 12345; ``` Your array 'A' only has room for one item and you are adding something at the index 100.

Comments: Yes, code is invalid and was used for example only! And i MUST have OutOfRange Exception. But after using Magick.NET (.NET 2.0 only) ``` MagickNET.SetTempDirectory(Path.GetTempPath()); ``` I am don't see any exception, only error message. How I can debug my app if I don't see exceptions in Debug mode? Just watch [video](https://youtu.be/P5MltQXd5x8)! P.S. When I said "works perfectly" I am talk about Visual Studio Debug works perfectly.

Created Unassigned: Draw() causes single channel image to become quad channel [1411]

I have a grayscale image, upon which I'm writing a string. While the drawing happens correctly, as soon as the Draw() method is called - whether for text, a line, or anything else - the single channel grayscale becomes an RGBA image.

To diagnose, I called GetPixels().ToArray().Length before and after the Draw() call. The image is a 1029 x 1029 image.

Before: 1058841
After: 4235364

Sample code
```
image.ColorSpace = ColorSpace.Gray;
image.ColorType = ColorType.Grayscale;
Console.Write(image.GetPixels().ToArray().Length);
image.Settings.ColorType = ColorType.Grayscale;
image.Settings.FontFamily = "Lato";
image.Settings.TextGravity = Gravity.Center;
image.Draw(new Drawables().Text(0, 0, "Test"));
image.Draw(new DrawableLine(0, 0, 1029, 1029));
Console.Write(image.GetPixels().ToArray().Length));
```

Also, if I force it back to ColorSpace.Gray after all this code is called, the array returns: 2117682. Safe to assume this is an alpha channel included with the gray channel.

Comments: This is the expected behavior. The Draw methods will turn on image into RGBA for a better result. Turning the alpha channel off and setting the colorspace to gray should get you back to a single channel.

Hi, i load a .hdr image in a MagickImage and then change the value of a pixel to {0,0,0} (the image has 3 channels. What happens is that after the first pixelCol.Set(x,y, black) everything becomes (0,0,0). I can't understand why. The sample code is reported here:
```
void mymethod(ref MagickImage image, double[][] pixelSet, float[] black)
PixelCollection ps = image.GetPixels();
Pixel p;
foreach (double[] pixel in pixelSet)
{
if (mycondition)
{
p = ps.GetPixel((int)pixel[X_COMP], (int)pixel[Y_COMP]);
Console.WriteLine("Before: " +p.ToColor().R + " " + p.ToColor().G + " " + p.ToColor().B);
ps.Set((int)pixel[X_COMP], (int)pixel[Y_COMP], black);
p = ps.GetPixel((int)pixel[X_COMP], (int)pixel[Y_COMP]);
Console.WriteLine("After: " +p.ToColor().R + " " + p.ToColor().G + " " + p.ToColor().B);
}
}
```

The code returns
> Before: regularfloat regularfloat regularfloat
> After: zero zero zero
For the first iteration, and
> Before: zero zero zero
> After: zero zero zero
For all the others iterations. I tried skipping the first iteration and the result is the same but starting from the second iteration.

I cannot reproduce your issue with the following code: ```C# using (MagickImage image = new MagickImage("logo:")) { using (PixelCollection ps = image.GetPixels()) { float[] black = new float[] { 0, 0, 0 }; Pixel p = ps.GetPixel(0, 0); Console.WriteLine("Before: " + p.ToColor().R + " " + p.ToColor().G + " " + p.ToColor().B); ps.Set(0, 0, black); p = ps.GetPixel(0, 0); Console.WriteLine("After: " + p.ToColor().R + " " + p.ToColor().G + " " + p.ToColor().B); p = ps.GetPixel(1, 1); Console.WriteLine("Other: " + p.ToColor().R + " " + p.ToColor().G + " " + p.ToColor().B); } } ```

I have noticed issues when converting large PDF (3.5MB and higher) that it freezes the system, and in the course of 5 minutes will create temp files over 10GB in size.

Let me know if you need any info
Comments: When you append the images you will need to load all off them. If you have too many images it will be cached on disk instead of memory.
