The menu contains commands to open, acquire, close, save and print images with paint.net. These options behave similarly to other document authoring and image editing programs.
This creates a new, blank, single layered image. The single layer will be filled with white.
The default canvas size is 800 x 600 pixels, or the size of any image contained in the clipboard.
This dialog is displayed when is invoked.
An estimate of the image size is displayed at the top of the dialog. This can be used to approximate how much memory paint.net will require to open the image. Adding new layers will increase this memory overhead. The saved size of the image will usually be less than the new image size. This is because compression is used by most file formats.
This allows you to open an existing image for editing. The opened image will be added to the image list and displayed in the
Did you know you can open an image from a URL? Simply paste the URL of an image into the Filename text box in the Open dialog and click Open.
Note: Use to save changes to the image as you won't be able to save back to the original URL.
Illustrated above, sub-menu allows quick access to the last eight images opened with paint.net. Each image is accompanied by a thumbnail to help with identification.
There is a command to in the sub-menu. This removes all entries from the list which can be useful if the image directory has been changed or renamed.
This sub-menu contains one item: . This allows a new image to be acquired from either a scanner or camera attached to the computer. The scanner or camera must support Windows Image Acquisition 2.0 (WIA).
This closes the current image. If there are unsaved changes, a prompt will appear asking for confirmation before the closure proceeds.
This command saves the image with the current filename. If the image has not been previously saved, or if the file type specified requires configuration (PNG, BMP, GIF, TGA or JPEG but not PDN or TIF), then the Save Configuration dialog will be presented. If the image is unnamed (that is, if it's still called "Untitled"), a filename will need to be supplied.
When saving JPEG images, the quality of the image can be configured. For GIF images, transparency and dithering options are presented. TGA images may be configured to save at 24 or 32-bit, and with or without RLE compression.
The dialog below shows a preview of how the image will appear when loaded with another application (or paint.net). The file size is shown below the preview. The configurable options help optimize quality vs. file size.
The Auto setting is used to ensure an image is saved to the smallest file size that does not incur any loss of information or clarity.
Paint.net first determines at which bit depths the image can be saved at without fidelity loss, then the image is saved at the setting which results in the smallest file size.
When using the command the filename, format location and settings previously specified will be reused to overwrite the existing image. The command allows a new name, format, location and settings to be applied. This is extremely useful to create a copy of an edited image while retaining the untouched original.
This command opens the built-in Windows Photo Printing interface so the image can be sent to an attached printer. The Printing Interface presents a simple wizard-based dialog to guide users through the printing process.
Use this to exit (close) paint.net. If unsaved changes have been made, a prompt will appear giving the option to save the image(s)before the application exits.
