I don't know if this is useful to you, but you can easily blend the techniques. For example, a 70% blend in Lab colorspace between bilinear and shepards (power 3), Windows script: convert ^ ( -size 200x200 xc: ^ -sparse-color Bilinear ^ "30,10 red 10,80 blue 70,60 lime 80,20 yellow" ) ^ ( ...

I've never used Windows 8, and don't know how it differs from 7. Some obvious things to try:

Does convert.exe exist in C:\Program Files\ImageMagick-6.8.6-Q16?

Can you run "C:\Program Files\ImageMagick-6.8.6-Q16\convert.exe"?

If you rename convert.exe to imconvert.exe, does it run then?

The image has dark text on a transparent background. Using IM v6.8.6-0 on Windows 7, a simple conversion ... convert 0726.pdf p.png ... gives me a result with visually the same colours and tones as Adobe Reader X v10.1.7. I can't see any difference. The above command leaves the transparent areas tra...

Can you supply a sample PDF that gives the problem?

The subimage-search technique could find the white pixel nearest the centre: crop into two, "-flip" the top half, "+append" them together, then search for the first white pixel. The y-coordinate tells if it is in the top or bottom half.

The result of fmw42's process will be an image 1 pixel wide by (n) pixels high. Suppose this is "w2.png". To find the first (highest) white pixel: compare -metric RMSE -subimage-search w2.png xc:White NULL: The result (sent to stderr) might be: 0 (0) @ 0,5 So the fifth pixel down (counting...

If removing the height eliminates pixellation, you should be able to see that.

Can you provide the input and output files, and values used for width and height?

A few rules of thumb: 1. Some cameras have a facility to print the date on the image, when the photo is taken. That would probably give the best result. 2. I don't work from jpeg sources if something better is available. This probably isn't a choice for you. 3. I generally (but not always) can't see...

As the exception is from Imagick, which isn't ImageMagick, we're unlikely to be able to help.

However, if you can narrow it down to an ImageMagick error, and can provide the exact command used and the source images, perhaps we can help.

Perhaps the OP wants to dissolve (aka cross-fade) the last (n) frames with the first (n) frames, like a conventional cross-fade from one video clip to the next. I would do that in a script, looping through the (n) frames, with an appropriate blend. The basic command is ... convert frame_000090.png f...

1. Not with IM, no. GS might be able to do this.

2. No, IM can't create vector text.

Various publishing and word-processing software can easily handle vector text on raster images. OpenOffice is an obvious choice. For more complex vector graphics, Inkscape might be useful.

The Hugin toolset can be used fairly easily to get the a,b,c radial parameters for a given lens at a given focus (and given zoom, if appropriate). However, these don't correspond to any of the five parameters in the OP. I don't know what those are. They seem to also have a tangential correction, whi...

How can I make the XML changed to RSVG. I don't understand the question. You may get better results by using Inkscape as the delegate. To do this on Windows: 1. Install Inkscape (from http://inkscape.org/download/?lang=en ). 2. Note the directory of inkscape.exe. Add this to your path, eg for a tem...

I resize in sRGB space. Even when blowing up pixels, I can't see any difference between this or converting to RGB or Lab before the resize, and then converting back to sRGB. "compare -metric RMSE" confirms the difference is < 1%. I think colorspace would matter less when upscaling. Sorry,...

If you want to create a few frames that blend from the final frame to the first, see http://www.imagemagick.org/script/comma ... .php#morph
