This option saves the current file, allowing
you to select a file name from a standard Windows Save As dialog
box. It may be used to save a cropped or otherwise modified
image. ThumbsPlus currently supports several types to save as:
BMP, GIF, JPG, TIF, TGA and PCX for images, and WMF for metafiles.
Some file types also have optional information
(such as comments) which can be saved in the file. If there
are options available for the type you select, an Options dialog
box will appear after you click OK in the Save As dialog box.
The JPEG Save Options
dialog box even shows a preview of the "lossiness"
of the compression.
The TIFF Save Options
dialog box allows you to set the compression and resolution
of the file, and to add or modify image comments.
The GIF Save Options
allows you to specify the GIF level of the output, and to add
or modify image comments.
If the current file has an extension representing
another format (such as .PCX or .CGM), it is changed to reflect
the format being saved.

As - JPEG
Quality. Select
a quality value, between 1 and 100. Values between 25 and 95
are recommended. Values below 25 are likely to degrade the image
far too much, and values above 95 make the file larger without
any appreciable quality increase.
Smoothing. This option is sometimes useful
for storing dithered 256-color images as JPEGs; it attempts
to smooth the differences between pixels caused by dithering,
but tends to blur the image somewhat.
Grayscale. Stores the image as a single-channel,
8-bit grayscale image. This removes all color information from
the image.
Comments. Click on this button to edit
or add comments to the image file.
Preview. Allows you to see the effect
of the lossy compression on the image. You may scroll this preview
around to different parts of the image to see the effect on
specific details. The Delta option shows the differences between
pixels, before and after compression. Medium gray is "zero
difference."
A truecolor or highcolor (24-bit or 16-bit)
display driver is required to utilize the JPEG loss preview.

As - GIF
GIF files may be saved as the older 87a
format, or the newer 89a. Version 89a files can have
comments, which you can edit by clicking the Comments
button.
You can specify the background color and
size, and select a transparent color.
You can click anywhere on the preview image
to select a color as transparent.
You can also save GIF files as interlaced,
which allows them to display progressively over slow communications
links.
If you select Minimize Size, ThumbsPlus
will automatically reduce the color palette to the minimum size
(by combining duplicate palette entries), and create the smallest
size of GIF file that it can.

Compression.
None is the most compatible with other
applications, and fastest to load.
LZW is best for 8-bit color and grayscale,
and for 24-bit color files.
CCITT Group 3 and CCITT Group 4
are valid only for bi-level files.
Best Fit will cause ThumbsPlus to use
CCITT group 4 for any bi-level files, and LZW compression
for any others.
Comments. Allows you to edit the contents
of the TIFF Description tag.
Resolution. Allows you to set the suggested
resolution for the image, in dots-per-inch or dots-per-centimetre.
Separate color channels. Allows you to
store RGB (Truecolor) images in separate red, green and blue
channels.
