Documentation of the options is at http://www.imagemagick.org/script/command-line-options.php "-opaque {colour}" means "change pixels that are currently {colour} to the fill colour". If fuzz was zero, only pixels that were exactly {colour} would be changed. With a fuzz of 15%, a...

I have a logo .png file (only words) in red color with transparent background. Is there a command line to change the color of the words from red to yellow? Depending on your version of IM one or both of these should do what you describe... convert logo.png -fill yellow -colorize 100 logo_out.png co...

Hi all,

Following command helps me out:
⟫ convert traces_of_life_10_en.png -fuzz 15% -fill yellow -opa
que "#c03030" traces_of_life_10_en_yellow.png

I found it on Internet

Could you please help me to understand;
-fuzz 15%
-opaque "#c03030"
?

Thanks

Is it possible to do follows; 1) Changing ONLY WhatsApp on the file to red and other text remaining in black? 2) Adding the word 'public' in red before Wi-Fi connection? 1) You would have to create a black/white mask to use to select where you wanted to change to red and where to leave as black.

- snip - 1) Yes you can combine pages from one PDF with another PDF, but you have to rasterize both PDFs to the same density and then enclose that rasterized image in a vector PDF shell. So the text is no longer vector text and cannot be edited in a PDF editor. 2) ImageMagick does not have any cont...

Yes, hex colors are permitted. On unix systems, they need to enclosed in quotes as you have done. See the following for the forms of colors that IM can handle: http://www.imagemagick.org/script/color.php Following command works for me.

If I expect adding further image; chinese-flag-waving-gif-animation-10.gif This is harder and requires special techniques to add an animation to a static image. See http://www.imagemagick.org/Usage/anim_mods/#background. And it has to be saved as GIF not PNG. Note I have reduced the size of your wa...
