Loading and Saving Images
58
To Save Using a Different File Folder, Name or Type
From the File menu choose Save As. The Save window will appear.
Select the file type that to use from the drop-down list near the bottom of the window.
Navigate through the drive and folder structure to the location to save the image.
Enter a filename for the image.
Click Save.
Burn in Changes to a New Image
The Burn Changes to a New Image command takes all the changes made to the image and creates a
duplicate copy in a new file. This process is called "burn" because once the changes are made, they are
not reversible. Burning changes to a new image is useful when creating a document or presentation.
Click onto Burn changes to a new image from the Filters plug-in or use the Image > Filters > Burn
changes to a new image command.
A second copy of the image will appear in a new image window as an untitled image.
Image File Types
Images are saved as two separate files. While the two files have the same name, they have different
extensions.
The Image File
The more important of the two files is the Image File, as it contains the actual image. It is saved in the
image file format (file type) selected when saving, which is JPEG by default. The file extension will reflect
the file format (e.g. ".JPG" for a JPEG file).
LS Software supports the following formats:
JPEG: Joint Photographic Experts Group. A common lossy compression image format used to
store images on disk. JPEG files generally have JPG or JPEG extensions.
TIFF: Tagged Image File Format, a common image format. Depending on settings, TIFF can be
either a lossy or a lossless compression format. In LS software, it is used in the lossless mode to
reduce image file size without losing integrity. TIFF files generally have TIF or TIFF extensions.
TGA: Truevision Targa image format. TGA is a lossless compression format that reduces file size
somewhat. TGA files generally have a TGA extension.
BMP: Microsoft Bitmap image file format. BMP is a lossless format which provides some
compression to reduce file size. BMP files generally have a BMP extension.
PNG: Portable Network Graphics, a common image format. PNG is a lossy compression format
that results in very small files. Files stored in PNG usually have a PNG extension.
GIF: Graphic Interchange Format, a proprietary Xerox image compression format. GIF is a lossy
compression format that results in very small files. Files stored in GIF usually have a GIF
extension.
JPEG, PNG and GIF are lossy compression formats. TIFF, TGA and BMP are lossless compression
formats (at least, as used by this software; TIFF can actually be either lossy or lossless). Lossy
compression makes small, usually non-visible changes to an image in order to make it store more
compactly on disk. Typically, formats that use lossy compression store in much less space than lossless
