Can I save the image object into hard disk?

klfun

Hi Matthias

I got an Image object in the following scripts:
------------------
img = RBA::Image.new(ncolumns, nrows, data)
img.pixel_width = xw
img.pixel_height = yw
img.trans = RBA::DCplxTrans.new(1.0, 0.0, false, RBA::DPoint.new(xmin, ymin))
------------------
Can I save the img into hard disk in some format? I cannot find a save method for Image object in the documents.

Thanks

Matthias

Hi,

the Image class was intended to background images, so you can load an image but not save it currently. That's what I meant in the other forum entry.

In addition the Image class provides functionality somewhat beyond the capabilities of the normal image formats - for example, floating-point pixel data.

You can use Image#get_pixel to get the pixel data for individual pixels but next thing is you have to find a way to write them to some file. If you want a text file that is straightforward and can by done within Ruby.

I think I got your point. Thanks a lot, Matthias.
