2.2. New…

Using the Create a New Image dialog, you can create a new empty image and set its properties. The image is shown in a new image window. You may have more than one image on your screen at the same time.

2.2.1. Activate the command

  • You can access the command in the Image menu through: FileNew…,

  • or by using the keyboard shortcut Ctrl+N.

The Template dialog

Rather than entering all the values by hand, you can select some predefined values for your image from a menu of templates, which represent image types that are somewhat commonly useful. The templates set values for the size, resolution, comments, etc. If there is a particular image shape that you use often and it does not appear on the list, you can create a new template, using the Templates dialog.

Mida de la imatge

Here you set the Width and Height of the new image. The default units are pixels, but you can choose a different unit if you prefer, using the adjoining menu. If you do, note that the resulting pixel size is determined by the X and Y resolution (which you can change in the Advanced Options), and by setting Dot for Dot in the View menu.

If no image is open, the New image is opened in the empty image window, with the default size you have determined. If you open the Newimage when another is open (or has been), then it is opened in another window, with the same size as the first image.

[Nota] Nota

Keep in mind that every pixel of an image is stored in memory. If you create large files with a high pixel density, GIMP will need a lot of time and memory for every function you apply to the image.

Portrait/Landscape buttons

There are two buttons which toggle between Portrait and Landscape mode. What they actually do is to exchange the values for Width and Height. (If the Width and Height are the same, these buttons are not activated.) If the X and Y resolutions are not the same (which you can set in Advanced Options), then these values are also exchanged. On the right of the dialog, image size, screen resolution and color space are displayed.

The Advanced Options are mostly of interest to more advanced GIMP users. You can display these options by clicking on the small triangle on the lower edge of the dialog window.

X and Y resolution

The values in the X resolution and Y resolution fields relate mainly to printing: they do not affect the size of the image in pixels, but they may determine its physical size when it is printed. The X and Y resolution values can determine how pixels are translated into other measurement units, such as millimeters or inches.

If you want to display the image on the screen at the correct dimensions, select ViewDot for Dot Set the zoom factor to 100% to see the image at its true screen size. The calibration of the screen size is normally done when GIMP is installed, but if the image does not display at the correct size, you may have to adjust the screen parameters in the GIMP. You can do this in the Preferences dialog.


You can create the new image in different color modes, as either an RGB image or a grayscale image.

RGB color

The image is created in the Red, Green, Blue color system, which is the one used by your monitor or your television screen.


The image is created in black and white, with various shades of gray. Aside from your artistic interests, this type of image may be necessary for some plug-ins. Nevertheless, the GIMP allows you to change an RGB image into grayscale, if you would like.

You cannot create an indexed image directly with this menu, but of course you can always convert the image to indexed mode after it has been created. To do that, use the ImageModeIndexed command.


Here, you specify the background color that is used for your new image. It is certainly possible to change the background of an image later, too. You can find more information about doing that in the Layer dialog.

There are several choices:

  • Fill the image with the current Foreground color, shown in the Toolbox.

    Note that you can change the foreground color while the New Image dialog window is open.

  • Fill the image with the current Background color, shown in the Toolbox. (You can change the background color too, while the dialog window is open.)

  • Fill the image with White.

  • Fill the image with Transparency. If you choose this option, the image is created with an alpha channel and the background is transparent. The transparent parts of the image are then displayed with a checkered pattern, to indicate the transparency.


You can write a descriptive comment here. The text is attached to the image as a parasite, and is saved with the image by some file formats (PNG, JPEG, GIF).

You can view and edit this comment in the Image Properties dialog.
