Before you save an image, you need to consider the file format in which you want to save it, and you must ensure that you don’t overwrite an original image that you may need in the future.
The PspImage file format of Corel PaintShop Pro supports layers, alpha channels, and other features used in creating images. It is recommended that you save and edit your images as PspImage files. You can then save the files to common file formats. You can also use the Save for Office command if you want to optimize your images for placement in another application, such as a page layout, e-mail, or Web page design application.
The following list provides basic information about common file formats:
| • |
JPEG — a standard file format for digital photos that is suitable for e-mail and the Web. It uses lossy compression, which ensures a small file size but entails a loss of image data each time you save. For this reason, this format is not recommended for editing photos unless a high quality setting is used. This file format supports EXIF and IPTC data, which can be used to provide information about the photo, such as when a photo was taken. |
| • |
TIFF — a standard file format for printing and sharing images between programs. This file format uses non-lossy compression. Although you do not lose image data when you save the file, the larger file size is less suitable for e-mail and the Web. TIFF can save data in the CMYK color mode for printing, and it supports EXIF and IPTC data. |
| • |
PNG — a file format widely used for Web images. It uses non-lossy compression to reduce the file size without losing image data. |
| • |
RAW camera formats — a file format typically used by professional photographers. RAW camera formats provide uncompressed, unprocessed image data and gives you the most control over how an image is processed. You must have a camera that captures digital image in a RAW format, and you need software that lets you open and work with the file, such as Corel PaintShop Pro. |
You can save a PspImage file with or without compression. Both compression methods that Corel PaintShop Pro uses are lossless and reduce the file size without losing any image information. Uncompressed files require more disk space.
Corel PaintShop Pro uses the following compression methods:
| • |
Run length encoding (RLE) — a fast compression method, which compresses most multilayer images to about 75 percent of their original size. This method works well with images that contain large areas of the same color. |
| • |
LZ77 compression — a slower compression method that compresses most images to smaller sizes than with the RLE method. This method works well with photorealistic images. |
When you save a new image, Corel PaintShop Pro lets you select its location, name, and file format. When you save an image and then edit it, the image title bar displays an asterisk, or modifier tag, after the filename to indicate that the file has been modified. This tag disappears each time you save your work.
You can also automatically save your files at specific intervals to avoid losing your work if your computer shuts down unexpectedly. For more information, see Setting Autosave preferences.
If you want to save a version of a file, you can save a copy of an image. This is useful when you want to apply effects to an image but keep the original file.
Important! The Auto-Preserve Original preference setting can help you avoid overwriting original images. By default, this feature is on. For more information on this preference setting, see Setting Auto-Preserve preferences.
