Thanks for getting the library fixed.
The sample code was just a test of concept before it was implemented.

New Post: Embedded ICC profile issue
I don't have or use Photoshop so I cannot run some tests myself. Is it possible that Photoshop is complaining about an Adobe RGB color profile in a GrayScale image?

New Post: Embedded ICC profile issue
I suppose it's possible. But Photoshop is able to open up the original just fine. And within Photoshop, if I save that as a jpg, that's fine as well. I'm not sure where to look next.

Can you e-mail me the jpeg you saved from Photoshop so I can compare it with the image created by Magick.NET?

Jumping in here. With Adobe Photoshop CS4 Extended I get an error with the image.

New Post: Block Processing For Large Images
Is there some type of block processing in IM so I can handle very large images? See link for details http://www.mathworks.com/help/images/examples/block-processing-large-images.html
I'm trying to Canny process a 400 DPI image 16800 x 12000 pixel, 1bpp, Group IV compressed image and it takes a long time. Actually I'm not sure it will complete because I'm too impatient. I've waited 5 minutes and killed it because it just was taking too long. So I was wondering if there was a way I could process a block at a time, show the results, then move to the next block.
Here's link to the file http://1drv.ms/1gDBrPs
Thanks,
Darren

Hmmm. I guess I used a different version when I ran my test. Sorry about that guys. And thanks

New Post: Converting a PDF to JPG and then scaling turns the image black
My code to convert a PDF file to JPG works great, but if I try to use images[0].Scale(50.0,50.0); where images is an ImageCollection and images[0] is an Image that appears fine when written; it will scale my image down, but it turns the majority of the image solid black. Is there a setting I can set or better way for resizing images based on percentage that are in an ImageCollection?

New Post: Merging Images Together
I've asked this question once before, but the original solution no longer works after I recently upgraded to the newer Magick.NET.
I am trying to put an image on a white background. My 'output' must be a specific size, so I am putting a white background behind any image uploaded so that it always ends up the correct size. The code below works, except that the 'from' image needs to be centered. I used to be able to center it, but that option gives a compile error now.
I just need to know how to do the 'merge' and center the top image.

MagickImage first = new MagickImage(Color.White, newP.X, newP.Y);
first.Density = new MagickGeometry(300, 300);
first.BitDepth(24);
if (first.ColorSpace != ColorSpace.sRGB && first.ColorSpace != ColorSpace.RGB)
{
first.AddProfile(ColorProfile.SRGB);
first.ColorSpace = ColorSpace.sRGB;
}
if (strNewExt.ToLower() == ".tiff"

New Post: Converting a PDF to JPG and then scaling turns the image black
This happens with every PDF I try. Here's an example:

http://msiatlanta.com/kb/index.php?View=file&EntryID=3
MagickReadSettings settings = new MagickReadSettings();
settings.Density = new MagickGeometry(144, 144);
foreach(string PDF in PDFs)
{
using(MagickImageCollection images = new MagickImageCollection())
{
images.Read(PDF, settings);
int page = 1;
foreach (MagickImage image in images)
{
image.Write(PDF.Substring(0, PDF.Length - 4)+" Page "+page+".jpg");
page++;
}
images[0].Scale(95.0, 95.0);
images[0].Write(PDF.Substring(0, PDF.Length - 4) + " High.jpg");
}
}

New Post: Converting a PDF to JPG and then scaling turns the image black
This is happening because the background of your PDF is transparent. When you save it as JPEG this will turn black for your PDF's. You should change the transparent pixels to a color with the ColorAlpha method:
foreach (MagickImage image in images) { image.ColorAlpha(new MagickColor("#fff")); image.Write(fileName.Substring(0, fileName.Length - 4) + " Page " + page + ".jpg"); page++; }

New Post: Block Processing For Large Images
I used image.GetReadOnlyPixels to 'Clone' parts of the image but I am unable to reproduce the code from the posted example. I think you will have to do some trials for yourself to see if you can get it working.
↧
New Post: Merging Images Together
I think you can do this much easier with the Extent method of MagickImage.
MagickImage image = new MagickImage(strTempFile); image.Extent(width, height, Gravity.Center, new MagickColor("#fff"));

New Post: Color Profile is null. I might be missing something
Using the following image, the color profile at the end(cp1) is null when reading after a conversion.

The code is:

The code is:

string sourceFilePath = "sourceFile"
MagickImage magickImage1 = new MagickImage(sourceFilePath);
magickImage1.Strip();
magickImage1.Format = MagickFormat.Png;
magickImage1.Density = new MagickGeometry(300, 300);
destinationStream.SetLength(0);
magickImage1.Write(destinationStream);
MagickImage magickImageDestination;
destinationStream.Seek(0, SeekOrigin.Begin);

That worked. Is this documented anywhere? It would have saved a ton of time to know about the 'Extent' command.

You could have found it by going to the following page 'Cutting and Bordering' (http://www.imagemagick.org/Usage/crop/) from this page: http://www.imagemagick.org/Usage/. This link is also on the bottom of the documentations page of the Magick.NET project.
