Re: how to deal with space in folder name?

Please always state your platform. I assume it is Windows.

Windows directory separators are backslashes "\" not forward slashes "/".

If the directory or filename contain spaces, use double-quotes:

Code: Select all

-path "C:\Dropbox (Personal)\Scannade dokument\Epson\My messages\Test\Output\"

Re: Batch changing picture files

Change black to red That would be: -fill Red -opaque Black (or even better, if it is possible to get the program for each file to stop and ask me for which color to change to) IM can't do that. Instead of mogrify, you could have a shell loop to process the files, with the shell asking the user for ...

Re: Test to image compress not working

It works fine with v6.9.9-50. Your version is very old. I suggest you upgrade.

Re: how to remove vertical and horizontal line in this image

Here is a more accurate result that makes the top and bottom printed lines straight and horizontal, following the method explained in Straightening two lines . First, we create an image that is black in the middle, and blue at the top line and above, and blue at the bottom line and below. The lines ...

Re: Convert image colorspace to rgb from cmyk without affecting image color contrast or color values

Do you have sRGB.icc in your current directory?

Did your convert command complete without error? Insert "-verbose" as the first option. What is the text output?

This is vectorization, conversion of a raster image (pixels) into vectors. IM can't do that. Programs that can include:

Potrace
Autotrace
Inkscape
Gimp
traceContours (by me, unpublished)

Re: How should I select specific transparent pixels in tiff file?

What version of IM, on what platform? The top-left pixel is at (0,0), so (1,1) is in the next column and next row. I don't understand what you want. IM doesn't really "select" pixels. Instead, we make a mask image where two colours represent selected or not selected. The mask can then be used to pro...

Re: how to specify diffferent color in a loop in script

For IM v6, use "convert" instead of "magick".

The command I showed makes a text output. For an image file, change "txt:" to "out.png" or whatever you want.
