Question
1. A person had been sent a file in GIF format and saved it as file "image.gif." For a particular application, the person wanted a file in JPEG format. Explain why the following approaches might or might not work. a) Change the name of the file from "image.gif't"image.jpg.."(This approach is not hypothetical-I have talked with people who have tried this, but might this approach work?) b) Use an image-processing utility, such as Photoshop, GIMP, or xpaint, to load the file "image.gif" and then use the "save as" feature to produce a new file "image.jpg." (I know people who have tried this approach too will this approach work?)Explanation / Answer
Solution to 1a
No. This approach will not gonna work.The Extension has nothing to do with anything really, it's just a hint to tell programs how to treat your file.They will just rename it to a different name.The operating system will be fooled though.
Solution to 1b
Yes, This approach will work.First we would have to load the file which is "image.gif" (in this case), then the photoshop or any other image processing utility would convert the to jpeg format. As the gif file may be of a couple of seconds, therefore the image file would contains a couple of images covering whole gif file, to prevent the lossy data of gif file while converting.
