Re: How to run program
You can do many things. I show a few thousand examples on my web pages. (Most examples were written for IMv6. For v7, change "convert" to "magick".)

Re: How to run program
ImageMagick is a command-line program. In Microsoft Windows, open a "Command prompt" (also known as "console") window. At the prompt, type "magick" and press return. This should show something like this: Error: Invalid argument or not enough arguments Usage: magick tool...
Re: deskew
Nothing wrong, as such. You are comparing the results from (a) contrast-stretch and then crop with (b) crop and then contrast-stretch. The images in these two cases are different, so the deskew angles are also different.jaffamuffin wrote:What am i doing wrong ?

Re: Histogram with c# Magick.Net
I'm still not sure what you are asking. A program can be written in whatever language you want that reads sliders and applies effects to images, with updates to a screen copy of the image in real time. I have done that, with C and ImageMagick (unpublished). Gimp is open source, so you can see how it...
Re: deskew
I don't understand your points 3 and 4. Showing the actual commands would help. Pre-processing before "-deskew" usually helps, eg: magick 300_01.tif ( +clone -fuzz 10% -fill White +opaque Black -deskew 40% -set option:DESK %[deskew:angle] +delete ) -rotate %[DESK] out.png This needs IM v7....

Re: crop to 1000*1200 px image non homothetic
I'm not sure what you mean. Perhaps: some images have the same aspect ratio as 1000:1600. but some don't. You can "-resize 1000x1600" to keep the aspect unchanged, or "-resize 1000x1600!" to make the result exactly that size. See http://www.imagemagick.org/script/command-line-pro...

Re: Adaptive sharpen slow - any way to speed up?
At 8 bytes/pixel, each copy of the 5760x3589 image needs 0.165 GB. Adaptive sharpen needs two more copies, so we need 0.5 GB. @ulrichlang: What is your command, and how long does it take? Eg "magick tmpimg.jpg -adaptive-sharpen 5x1 NULL:" on my 2.4GHz laptop takes 22 seconds. Check that no...

Re: Compare images and generate list of images which are not same
The inputs could be trimmed.
3. We can do things like this:
If we ">>out.txt", the results will be appended to out.txt.

Re: Newbie needs help with "color splash" using Python
I don't use Python. A command line could be (Windows BAT syntax):
Code: Select all
convert ^
colorWheel.png +write mpr:INPT ^
-alpha Set ^
( +clone -fuzz 30%% -transparent Blue ) ^
-compose DstOut -composite ^
( mpr:INPT -colorspace Gray ) ^

Re: How delete rows from pictures?
For the examples given, connected components would work. Turn non-white into black, with a fuzz factor eg 5% because the input is JPG. Find the largest black object. Use that as a mask to get just the object. magick dimmed02.jpg ^ ( +clone -fuzz 5% -fill Black +opaque white ^ -define "connected...

Re: Do the Windows binary releases contain Magick++?
If I knew the answer, I'd happily tell you.
At the binary installation, there is a option for "Install development headers and libraries for C and C++". I've never tried this, and don't know if it provides whatever your build tools need.
Perhaps you can try it, and tell us if it works?
