Batch magnify from a folder to an another one [solved]

[kimono]

@snibgo and @fmw42: Thanks for taking your time to solve this problem. When I want to execute this command line, I've got the following message:

Code: Select all

This app can’t run on your PC.

Access Denied.
I dowloaded both ImageMagick-7.0.8-39-Q16-x64-dll.exe static and dynamic version and have the same result.
I'll try to change some win10 authorizations...thanks for your help.

This app can’t run on your PC.

This message is from Windows, not from IM.

An internet search suggests you may have 32-bit Windows but have installed the 64-bit version of IM.

@snibgo: I tried the 32-bit version in win10 static and dynamic and it doesn't seem to work better (I will try to install win10 in another drive later).
I installed the version you suggested me on a PC with windows seven and I've got some progress.
Here's my command line:

Code: Select all

magick.exe mogrify -path Karatedo/KaratedoX2 -magnify *.png

I have this reply:

Code: Select all

mogrify: unable to open image *.png: invalid argument

With * space .png, I've got this:


P.S: You can see/try my game here:

The sprites are doubled sized with nearest neighbor and I want to try magnify (and rework on them) if the result is slightly better.

Are you running in Unix mode? If not, then your path is using unix syntax / and should be windows syntax \. Also you have a space between * and .png which should not be there.

Try

Code: Select all

magick.exe mogrify -path Karatedo\KaratedoX2 -magnify *.png

Please do not post images of your processing/errors. Copy and past into here, highlight and use the </> button to make into code.

mogrify: unable to open image *.png: invalid argument

Do you have any png files in that directory? You seem to be in the root of C:. This is not a good place to put images.

@fmw42: Thank you I managed to convert all the image from one folder to an another one. The topic is solved thank to you @fmw42 and snibgo, I owe you one .

One last question: which command have the best result to shrink a pixelart image without having blurred pixels? Ex: I wish to resize an image at 70% of its original size and keep its colour palette.
Imagemagick will help me to gain tons of time with its batch function, thank you for this great software

Try "-scale" or "-sample".
