I've been looking for a way to convert IMG (Atari/Digital Research GEMpaint) files to something more common such as PNG and I was suggested XNconvert which does the job fine. I'm on the Mac OSX platform (OSX 10.9.5 Mavericks) and was hoping for a way to simply drag image files to an icon in the dock and have them converted to PNG.

XNconvert doesn't seem to allow that but someone suggested Nconvert to me which I've just downloaded. I've tried to make sense of the supplied files but am having trouble figuring it out:

1) how do I install it on a Mac?

2) how do I configure and make it possible to simply drag & drop IMG files to the dock and get them converted to PNG. Perhaps with an Applescript or Automator action. Has anyone done that?

3) I noticed that the Nconvert page says it's available for several platforms, among them the Atari (I suppose it's a reference to the Atari ST), but where do I download that version from? The download links don't show any Atari version.

Nconvert is a command line tools, no install.
You should try XnConvert that can convert atari images

Yes, I know it's a command line tool, but it needs to be put somewhere on the hard drive so it can be accessed from the Terminal. I couldn't find any such info in the documentation (which is mostly for PCs).

EDIT: I didn't find it in the docs, but in this posting it says that the nconvert binary should be put inside /usr/local/bin/
so that question is solved at least

XnConvert works fine, but I was suggested NConvert because it might be easier to work with scripts and thus make it possible to easily allow drag & drop to the Mac Dock and have IMG files converted that way. Suggestions on how I can do this?

UPDATE: I suppose I can get help with the script-writing in a Mac-specific group as long as I get the command line syntax right.
Using the information I got when entering nconvert -help I got a basic conversion working (after first changing the directory (cd) to where the IMG files are located):

nconvert -out png -v -xall -keepfiledate *.IMG

But I have a couple of problems with this:
a) it will only recognize the same case extension for the input files. It would be nice if it would process .IMG as well as .img and .Img
b) it won't keep the original filedate (instead if gives the converted files the time/date when they were actually converted today).

On the other hand I tried converting the same files with XnConvert and I didn't have any of these problems.
Using the "Save script as..." function in XnConvert I was able to see the settings I had configured it to do. The script file looks like this:

Code: Select all

<?xml version="1.0" encoding="UTF-8"?><XnView_script version="1.0" name="scripttest">
    <Output folder="/PATH/OF/MY/IMAGE/FOLDER/HERE/" filename="{Filename}" case="0" format="PNG">
        <Options overwrite="1" orgDate="true" keepMeta="true" keepICC="false" keepFolder="false" keepParentFolder="false" delOrg="false" multipage="false" allPages="false" openExplorer="false" openBrowser="false" clearItems="false"/>
        <PNG level="6" interlaced="false" filter="0"/>
    </Output>
</XnView_script>

Assuming nconvert and XnConvert is essentially the same software, what is the syntax for making NConvert do the same thing?

you need to add *.img *.Img ...

Keeping the original file date works only on windows, it's a known issue

So the following should handle the different combinations (there's no parameter for ignoring the case)?

nconvert -out png -keepfiledate *.IMG *.img *.Img

b) it won't keep the original filedate (instead if gives the converted files the time/date when they were actually converted today).

Is this a limitation with Nconvert or with Mac OSX?
So apparently the code from XnConvert is different from Nconvert: are there any plans to fix this in Nconvert?

Are there workarounds? Perhaps the "touch" command could be used, but how?

yes

Linux & MacOSX

There is some differences, yes i'll try to fix it

Code: Select all

touch -mt YYYYMMDDhhmm
