Using SuSE 8.2, we have recently moved into the realm of digital images with a canon Ixus II.With advice from the list we have downloaded images via a usb card reader and all is well. Yay, that is "Step 1- the hardest part" :g:
My question is in respect to mailing images. What is the best way in linux to compress a jpg file, I apppreciate that there are various programs which will compress files or pack files into a zipped file, however this is for my wife who is less versed in most things technical. A jpeg is a compressed file. It is compressed in a "lossy" way which means the higher the compression on the image the "blockier" it is. Trying to compress it again with another program [winzip, zip, arc, rar, gz, bz2] may even result in a larger file size.
Is there a simple method of reducing the size of a jpg file using Gimp or another image software package that will enable her to save the image as a smaller file (jpg) and send it via email still in jpg format? In Gimp, go to "Image" [or right click, depending on version, then go to "image" and then select scale image. My suggestion would be to scale it to around 800x600 for email purposes. You can then save it and set its "quality" at 0.75 to 0.85 to produce fairly good results :)
You could perhaps use the "convert" commandline tool [part of ImageMagick iirc] and use one of the gui script/programming languages to create something she can drag and drop to :) Hope this helps in some way, shape, or form :)
