Re: Batch chopping

original file name : Foobar_13-11-yyyy_07:49:39.png chopped image name : 49:39.png Note that the characters before the first colon have been removed. I suspect the problem is that IM regards characters in a filename before a colon to be the file type, typically "PNG:" or "TIFF:" etc. I suggest you ...

Re: deskew

Sorry I missed your IM version number. True, I don't get perfect results. Note that: tand(1.5)-tand(1.4544) = 0.0007964 So the error is less than 1 part in 1000. When we resize to be within a box 1000x1000 pixels, the error is less than one pixel. We can't hope for much better than this. If we don't...

Re: deskew

What version of IM? In my testing, that's around 144x144. Tried a couple of input images and got same results so it's repeatable. If you show your images, we can test your results. Are your images "clean", eg skewed white rectangles with black surround? If not, then the algorithm may be influenced b...

Re: Error Cross Refernce Guide

The error message about "scanline oriented access" has come from the TIFF library. I suggest you link to a sample file that has this problem.

Re: Multiple text caption per Image

"caption:" gives you a single image. You can do this multiple times to get multiple images. You can then combine these into a single image by appending or compositing them.

Re: Convert execution keeps on running.

Yes, "+repage" removes the canvas metadata. So does your "+repage" after the crop. Is the original canvas metadata meaningful after doing the roll and crop? If it is, you could save that metadata, perhaps calculate what the WxH+X+Y values should be, and restore those with "-page".

Re: ImageMagick does not start...

I suggest you run magick by typing at the command line, in a command window (aka "command prompt" or "console"). Or you can create BAT scripts, and run those from command windows.

Re: Convert issue bmp to PDF

For v7, I suggest you use "magick", not "magick convert" or "convert".

10127355-1.bmp is mostly transparent. "-alpha off" fixes this.

For a smaller PDF, use "-compress Zip" or some other compression method.

Code: Select all

magick 1012*.bmp -alpha off -compress ZIP out.pdf

But you say you are converting from BMP to PDF.

What are the generated command lines?

Please link to a sample input BMP and output PDF.

Re: convert: no decode delegate for image format `PANGO' @ error/constitute.c/ReadImage/560.

Sorry, I don't know how to install Pango on your system.

On Windows, Pango is included in the ImageMagick source zip file.

Re: Set white balance on CR2 conversion.

All is right, but I can't find how to set white balance option. IM delegates the reading of raw camera files to a delegate. "-verbose" may tell you what delegate is used. If that is in delegates.xml, eg a call to dcraw, then you can add any dcraw options you want, eg "-w". But if IM uses libraw, yo...

Re: ImageMagick does not start...

What version of IM, on what platform? Where did you install from? There should be no file "magic.exe". The correct spelling is "magick.exe". Does that file exist? What happens when you run it?

Re: Detecting blank scanned pages

The processing could be: deskew then trim the dark border. This gives you the scanned paper. Perhaps denoise. If the average luminance is close to 100%, the paper was blank. If you need further help, please say what version of IM, on what platform, and provide a sample of a blank page and a non-blan...
