Lossless rotation is possible by the use of jhead, which uses jpegtran to perform this job.

Just to clarify terms: I spoke of cygwin, which is a complete Unix bash shell under Windows (well, at least kind of, I hope). XAMMP, however, is a special WAMP (= Windows + Apache + MySQL + PHP), which is something different. In this environment, PHP cannot rely on certain Unix functionalities to be...

I remember that I once tested one of Fred's scripts under Windows, but I cannot find the corresponding thread on this forum. Anyway, my experience with it resulted in my remarks at http://www.imagemagick.org/Usage/windows/#cygwin, so I would rather try what's written there, instead of dealing with X...

Strange arrow head that you are drawing here ... I'm not sure what you mean by the arrow head following the main line, but what I would rather do is to define the entire arrow as one polygon object and then place it in its entirety by using translate (and possibly rotate) before drawing that object.

I gave it a check: I am working with ImageMagick 6.7.4-7 (January 2012) on Windows XP. The option -alpha remove resulted in the error message: UnrecognizedAlphaChannelType `remove'. It however helped to just choose the option -alpha off, which produced white background for any format. Strange enough...

Does that answer the question? If not, can you provide a sample input? No, it doesn't. I created a simple example, drawing a red circle and a blue quadrangle onto a blank page with Microsoft Word and then printing the page on a PDF printer (FreePDF aka FreePDFxp): http://www.unfallrekonstruktion.de...

When converting vector PDF pages to image formats that are aware of transparency, I often have the problem that the background becomes black, i.e. I would have to read black text on black background. Obviously, the canvas (i.e. the page) is considered to be fully transparent. (When converting to JPE...

And is it possible to start with output-01.jpg instead of output-01.jpg?

Add the option
-scene 1
to the command line.

Works just fine on my computer (Windows 7, ImageMagick-6.8.0-1). Try to convert the SVG to something simpler first, say GIF. If that works, PDF is the problem, not SVG.

Call unins000.exe with the option /verysilent and it will not ask you for anything.

By your notation I assume that you are working on a Windows computer, such that http://www.imagemagick.org/Usage/windows/#for_loops should provide you with the solution.

I wouldn't do it the "object way", but rather call Compare directly, analoguously to the way I call Identify in http://www.imagemagick.org/Usage/windows/#vb, first example. You can then either redirect the output to a file, as you are trying to do, or read it directly from stdout, as demon...

Does ImageMagick do this function? Why didn't you just try? It does the jobs your are asking for, especially the conversion of (possibly multipage) TIFFs into one PDF document. The page size will be adjusted to size. When converting several JPEGs into one PDF be aware that the JPEGs will be re-comp...

There is nothing wrong with that batch file. It runs fine on my Windows computer. There is also nothing wrong with setting SETLOCAL at the start of it. So I guess it is some mix-up with the Windows convert command. Rename the IM Convert into something else (e.g. IMconv.exe) and call that program in ...

EMF is a vector format and text is displayed as a vector object, i.e. defined by its oulines discribed in terms of Bezier curves. If you convert this into a raster graphic, it becomes blurry, especially as the rasterisation hints in the font file are usually ingnored by generic raster processors suc...
