files and read from them...
> Hi all,
> First, many thanks to the ImageJ development team. A great tool!
> I am a newbie at ImageJ and using Image1.46r.
> I have a little question about a macro: I like to read a value from an ASCII
> file an use it for the image properties Pixel "Width" and "Height" and
> "Voxel Depth".
>
> What I tried so far:
>
> // ~~~~~~Begin macro
> //1.) Choose Image tif File. (e.g:"1166-24.tif")
> //Note: Tiled Tiff. Open with ImageIO...
> run("Open ...", "Select Tiff File");
>
> ?
>
> //2.)Looking for the related ASCII file which should be in the same
> directory. The name is
> //equal, except the extension is ".tfw" instead of ".tif"
> (e.g:"1166-24.tfw")
> //----Begin file example----
> //0.250000 //--> This value is wanted
> //0.000000
> //0.000000
> //-0.250000
> //2598125.125000
> //1202999.875000//
> //----End file example----
>
> ?
>
> //3.) If the file is being found, read the value from the *first* row (e.g.:
> 0,250000) and copy it into "Image Properties...":
> //pixel_width=copy-value-here (e.g.:0.25)
> //pixel_height=copy-value-here (e.g.:0.25)
> //voxel_depth=copy-value-here (e.g.:0.25)
> //("Properties...", "channels=1 slices=1 frames=1 unit=m
> pixel_width=copy-value-here pixel_height=copy-value-here
> voxel_depth=copy-value-here frame=[0 sec] origin=0,0");
>
> ?
>
> // ~~~~~~End macro
>
> Many thanks for any help
