This tutorial is very easy, I realized that those who are completely fast graphics programs are also simple "scaling" the image and save it so compressed, it is not so simple a task, then I thought of writing sometimes the "Tutorial for denied. "
How to scale an image
1. Open the image manipulation program Gimp.
2. Open the image using File -> Open -> [select image]
3. From the horizontal menu Image -> Scale Image
4. Set the scale:
As you can see we can give different "parameters" to scale the image: *
width and height (which will remain proportionate if we let the padlock icon is closed), this we can define it in pixels (basic), but also in other units such as mm *
resolution that is expressed in pixels / in, ie DPI, that is, the dots per inch, the higher the number, the better the picture performance, but let us look well to the "what" we need the image if it is to be printed then 'll at 300 dpi, and should be read if only we can monitor the travel 72-100 dpi.
* quality, yet the scale of our original image we can decide whether the reduction process is more or less than quality, typically cubic interpolation (which is recommended) is of good quality.
5. Click on the "scale" and that's it ..!
in the next tutorial I will tell you for Dummies how to crop an image!
