That commit is not there, it is in the repository of ImageMagick. I did not rebuild Magick.NET yet with the new source code of ImageMagick. If this is really urgent for you (next release will be tomorrow or this weekend) then please contact me through CodePlex from my profile page and I can send you a development build.

You have found a bug in ImageMagick. Thank you for reporting this. I just submitted a patch to the ImageMagick repository. This will be fixed in the next release of Magick.NET.

Can you please reply to the e-mail I send you through Codeplex? We need a bit more information.

You may not know this currently, but any idea if this bug is constrained only to converting to .pdf's, or might it involve more conversion types?

New Post: Change DPI (resolution) but keep same size
Hi
Thank you for the reply, this is really helpful.
I have one more question, sorry for my poor knowledge, but how can i convert image to "GreyScale" using Magick.Net?
I tried a couple approach but was unsuccessful.
Thank you,

New Post: Not converting to PDF properly
It is limited to a small set of image types that cannot read directly from a memory blob. It this case it is happening because Magick.NET uses Ghostscript to convert the PDF. The following is happening:
- Format of data in stream is checked.
- If PDF then write the data of the stream to a temporary file.
- Tell Ghostscript to convert the PDF to a PNG file.
-
Read PNG files and return image.

New Post: ImageMagick reads/converts TrueColor TIF as Grayscale?
Hi, I have an uncompressed 24bit Tif image and I want it to stay TrueColor however:
wireframe.tif size is: 480 678 bytes (400x400x3)
same_wireframe.tif size is: 160 470 bytes (400x400x1)
The Command Line version of Image Magick behaves the same way so maybe I post this in the wrong place?
It seems that I can’t attach the images in this discussion but the same thing happens with every 24bit image storing grayscale color information.
For example: I created a new RGB image in Gimp with white background than I painted to it with black paintbrush and exported it as uncompressed Tif.

Image Magick Command Line

using (MagickImage image = new MagickImage(@"F:\wireframe.tif"))
{
ColorType ct = image.ColorType; //ColorType.Grayscale
ColorSpace cs = image.ColorSpace; //ColorSpace.GRAY
image.Write(@"F:\same_wireframe.tif");
}

You should set the ColorSpace of the image:
image.ColorSpace = ColorSpace.GRAY;

Magick.NET does not use ImageMagick 7 yet so there could be some differences between Magick.NET and the command line. Feel free to post your questions that are related to ImageMagick here. I am also involved in that project. Can you post a link to your tif image so I can run some tests with it?

New Post: ERROR: Type 'ImageMagick.MagickImage' is not defined.
That is a strange error message. maybe the dll cannot be loaded? Did you install Visual C++ Redistributable for Visual Studio 2012 (http://www.microsoft.com/en-us/download/details.aspx?id=30679) on your server?

New Post: ERROR: Type 'ImageMagick.MagickImage' is not defined.
Surely that is the problem ... in any case it is a server hosting and I have no way of checking if Visual C++ is installed or not, and I can't install it ... it's a shame.
Thanks for your reply.
Thanks for your reply.

New Post: ImageMagick reads/converts TrueColor TIF as Grayscale?
It turns out that this change in colorspace is by design. ImageMagick detects the image can be changed to Grayscale. This will save space when the image is saved. If you want to get the original colorspace you should use the following code:
image.GetAttribute("tiff:photometric");↧

New Post: Combining two multi-page TIFF images
Hello,
I am trying to get Magick.NET to merge two multi-page tiff files into one multi-page tiff file. I am creating a MagickImageCollection variable for both of the tiff files I want to merge. Then, I create another MagickImageCollection that I will add them to. Unfortunately, I do not know how to put a collection inside of another collection. The Add function does not accept a Collection, and the Read function gets rid of the first one that is read in when I go to read the second in.
If someone could help, I would appreciate it. Thank you
Corbin

New Post: Combining two multi-page TIFF images
Hi I have to do the same thing so here is how I solved this:
I think you can also do this:
public static void stackImages(string firstImagePath, string secondImagePath, string multiPagedImagePath)
{
using (MagickImageCollection multiPagedImage = new MagickImageCollection(firstImagePath))
{
multiPagedImage.Add(secondImagePath);
multiPagedImage.write(multiPagedImagePath);
}
}I think you can also do this:
public static void stackImages(string[] imagePathsToInsert, string multiPagedImagePath)
{
using (MagickImageCollection multiPagedImage = new MagickImageCollection())
{
foreach ( string imagePath in imagePathsToInsert)
{
multiPagedImage.Add(imagePath);
}
multiPagedImage.write(multiPagedImagePath);
}
