How to apply shadow to all side of image

[durga1208]

I am able to generate shadow with following code but shadow generating only right bottom. I want shadow all sides of images.

image2.Shadow(5,5, 10, new Percentage(10),MagickColors.WhiteSmoke);

The next version of Magick.NET will include a fixed version of the Shadow method. It now automatically draws the shadow behind the image. This will prevent you from being able to draw a shadow on all sides. After the fix only the shadow will be drawn and you will have to draw your image over if with Composite yourself.

Do you have any information on next release.

[dlemstra]

Can you share a sample image where you want to add a shadow to?

I am generating image from pdf and trying to apply shadow.

If you add a link to the PDF or image I can see what you are trying to accomplish.

I am trying to generate image with drop shadow with all sides from https://sitecorepractice.files.wordpres ... m_0613.pdf first page.

try the equivalent of -shadow 100x5+0+0 where 100 is darkest and 5 is distance. The +0+0 means not to offset in any direction.

Code: Select all

convert inputimage \
\( +clone -background black -shadow 100x5+0+0 \) +swap \
-background none -layers merge +repage \
outputimage

Hi dlemstra, can you please provide sample code for shadow.

Sorry for getting back to you this late but below is a translation of Fred his commands. It is not an exact translation but it should help you.

Code: Select all

using (MagickImageCollection pdfDocument = new MagickImageCollection())
{
  pdfDocument.Read("lcp-001_vectralcpprecmoldtg_am_0613.pdf");
  for (int i = 0; i < pdfDocument.Count; i++)
  {
    var backgroundColor = MagickColors.Black;
    if (pdfDocument[i].ColorSpace == ColorSpace.CMYK)
      backgroundColor = new MagickColor(0, 0, 0, Quantum.Max, Quantum.Max);

    using (MagickImageCollection images = new MagickImageCollection())
    {
      MagickImage shadow = pdfDocument[i].Clone(); // +clone
      shadow.Shadow(0, 0, 5, (Percentage)90, backgroundColor); // -background black -shadow 100x5+0+0
      shadow.BackgroundColor = MagickColors.None; // -background none
      // +swap changes the order of the images we just add them in a different order
      images.Add(shadow);
      images.Add(pdfDocument[i].Clone());
      using (MagickImage merged = images.Merge()) // -layers merge
      {
        merged.Write($"d:\pdf_{i}.png");
      }
    }
  }
}

The background color part is necessary because your PDF file appears to be CMYK and you will need to use a different color then.
