fmw42: I will try as you have suggested, but there's still a bug in the colorspace command if the image is 8 bit, so that's why I converted the depth of the image to 8 bit then next convert it to a tiff file before the colorspace command. I'll get back with you and let you know what I find. Snibgo: ...

Amendment to last sentence in second paragraph above:

I have manually calculated the Cielab variables from the RGB values output utilizing the -verbose info: command on the original RGB image and do get the calculated correct L* a* and b* values for the digital image.

I am still experiencing a couple issues/stumbling blocks to extracting the Cielab statistics from an image originally in RGB format. First, I can use the -verbose info: command to obtain the RGB values for the image, however when I utilize the command convert infile.jpg -depth 16 -colorspace lab -ve...

The first Window in this thread shows the Command line is " Convert infile -colorspace lab -separate outfile " wherein the generated output file to that command is a table displaying the mean, max, and min Lab values of the infile. When I use this command the output file does not display t...

I wanted to say thank you for all the help you provided guiding me through the enabling and running of external scripts to IM using Cygwin on a Windows 7 machine. As outlined throughout this thread, I was able to get the downsize script to work, however I did need to reinstall the script, append the...

Close, very close. When I follow your Pointers and enter the command line as you specified earlier in this thread, the script is attempting to do what the algorithm is directing it to do, however a window opens indicating " Windows can't open this file: downsize.sh ". Additional info in th...

I appreciate your help, but I need to ask for a little more guidance as some of the Pointers would be more familiar to a computer programmer than myself. Particularly, I need a better understanding of Pointers 2 and 3. Re: How To: Using Cygwin and Scripts (e.g., Fred's) with IM Pointers for use: Be...

STATUS UPDATE (Supplement): The three I eluded to above that worked were those utilizing the Convert command, not the Downsize command.

STATUS UPDATE: I have been successful with the first three suggestions by fmw42, however I did have to include colons after the C in the path names. I will know try to understand why the later two suggestions are not working. WRT to the question as to why I renamed the down loaded script, it was my ...

In addition to the 5 steps listed above, I also went into the Environment Variables' window of the computer's System Setting under Advanced Settings and appended ;C:\cygwin\bin to the Path name.

Correction to the 5) step in the previous note.

5) downsize -s 200 -t 1 -c y C/Chart2.jpg C/test2.jpg

If anyone can provide me direction/help, it would be greatly appreciated. 1) I have downloaded Cygwin with ALL add-ons including bc. 2) I have downloaded Fred's script "downsize", copied it to the bin folder of Cygwin, and renamed it as an exe file. 3) I have placed a jpg image on the c dr...

I am not a programmer, nor am I versed in photo-editing, and am having trouble utilizing published scripts with IM. Given my predicament, I am not able to successfully follow the instructions given on Fred's webpage that directs one to utilize Cygwin in combination with IM when utilizing a Windows 7...

I am looking for an individual who can help writing command line script with the following project flow; for steps not best handled by IM, or handled in a better way, an output file needs to be formatted to manipulate the data in another program (e.g., Excel). At present, currently available IM scri...

Thank you Snibgo. I did try using your suggestion, but the -depth script would not convert the jpeg file from 8 to 16 bit. I did however convert the jpeg file to a tiff file and was able to utilize the -depth script to convert the 8 bit file to a 16 bit file. The tiff 16 bit file could then be conve...
