software development and life.



One thing I noticed yesterday was the following. The Gimp uses the file extension to determine the format of picture when you save an image. So when you used ‘bla.jpg’ it will be saved as an Jpeg-file and when you use ‘bla.png’ the file will become a Png-file. Yesterday I edited a picture in Adobe Photoshop (It was not my own computer, so The Gimp was not installed). Whe I saved the picture, I used as file extension .jpg, assuming the picture will become a Jpeg-file. However, when I was reviewing it in another application, it complained about the file format and that it was not possible to open it… Investigation reveiled that the picture was saved as an Adobe PSD-file with the extension .jpg. Not very useable..
