Sorry, but I suspected that there is nothing like a "+region" option in ImageMagick. (I erroneously wrote "+reset" instead.) The Command Line Options page does not tell anything about there being a +region option. IM definitively crashes each time you use +region under Windows. T...

When developing a GUI for ImageMagick, you should take a look on AvsP, *the* editor for AVIsynth scripts, which nicely demonstrates how a GUI editor can simplify matters. To my taste, a GUI interface to ImageMagick should function pretty much like AvsP. But I rather think that an OS-dependent GUI do...

I have a JPEG 2000 image that I would like to analyse in some more detail. Most of all, I would like to know whether it was encoded losslessly. What makes me suspect this is that the JPEG 2000 version of the image (encoded as greyscale with 12 bit depth) is only slightly smaller than the 16-bit PNG ...

I just have had a stroke of genius
The solution is pretty simple: The option -region 100x100%+0+0 will select the entire image!

I wonder what you mean by "time stamp". Do you want to write it as text onto the image? (I first understood that you wanted to insert EXIF data or something. This is why I asked for the image format.) If so, you will find many hints at http://www.imagemagick.org/Usage/annotating, and http:...

I would check whether the filename is in the list via TYPE piclist.txt | FIND %%I IF ERRORLEVEL ... ERRORLEVEL will only be zero if the string is found. This seems to be an easier approach to the problem. Moreover, I would recommend that you develop the batch file step by step, first testing the cro...

What kind of image format are you dealing with? JPEG? (Because you spoke of EXIF.)

I am applying histogram corrections to three regions of the same image. After that, I want to draw a polyline onto the result. The code in the Windows batch file looks like this: convert %%~na-1.jpg ^ -region %WIDTH%x%STRIP%+0+0 -normalize ^ -region %WIDTH%x%IHEIGHT%+0+%STRIP% -contrast-stretch 2,0%...

Your question is more about Windows Batch file processing than about ImageMagick. And seeing this code doesn't make me believe that you are a coding novice. If you pass the filenames via the command line, it should however be FOR %%A in (%*) DO with a single percent sign, see http://www.imagemagick....

Anthony, I understood your first approach, in which you used -trim to determine the geometry of the red box. I think this is basically what I need, because I then have the geometry of the selection and can extract it from the output of Identify. And I don't mind the script producing some interim res...

I really don't understand the fuzz. We are converting PDFs to TIFFs and JPEGs with IM on a regular basis. And it is just as easy as skeched by me. Give me a link to your four pages PDF and I will give it a try.

Hi, I would like to manipulate an image like this: http://www.unfallrekonstruktion.de/bilder/Example.JPG that is I would like to make a selection on a larger photograph, scale it down and insert the original version of some section of the image as a detail enlargement. I am working under Windows and...

You are making things too complicated.

convert test.pdf test.tif

will already convert the PDF into a multipage TIFF, with no need for interim steps.

Example do not detail the handling of standard error output in windows. If there even is such a concept in BAT scripts. The example demonstrates how you read stdout of a DOS command into VBScript. You can then perform the testing of the value within VBScript and act upon the result. So I think that...

IM is not the right tool to do this. The easiest way to perform this task is to print the PDF via a PDF printer driver set to low resolution. This will leave vector objects and fonts untouched an re-calculate any raster graphics.
