-
- SECTION ONE:
-
- Installing PhotoGIF:
-
- PhotoGIF is an Adobe Photoshop file format plug-in. Unlike Adobe
- Photoshop filter, acquire and export plug-ins it will not work with
- other popular programs that support the Adobe Photoshop plug-in interface.
-
- The plug-in is based on version 1.0 of the Adobe Photoshop file format
- plug-in interface and should be compatible with versions 2.5.1 through 3.0.4
- of Adobe Photoshop.
-
- With Photoshop 2.5.1, simply place PhotoGIF in Photoshop's 'plug-ins' folder
- before opening Photoshop. If Photoshop is open when you place PhotoGIF into
- the 'plug-ins' folder it will not be loaded until the next time you start Photoshop.
-
- With Versions 3.x of Adobe Photoshop there are 6 folders inside of
- Photoshop's 'plug-ins' folder. You need to place PhotoGIF inside the
- 'File Format' folder, one of these six folders, before opening Photoshop.
- If you place PhotoGIF in the 'File Format' folder while Photoshop is
- running PhotoGIF will not load until the next time you start Photoshop.
-
- After PhotoGIF is installed Photoshop 2.5.1 will by default use it to open
- and save all GIF files. 'Save As' in Photoshop will allow you to set file
- options such as transparency, interlacing, and GIF version.
-
-
-
- SECTION TWO:
-
- Using PhotoGIF:
-
- PhotoGIF provides capability to save images previously converted to
- indexed color, bit-map and gray-scale modes in Adobe Photoshop as Compuserve
- GIF89a or GIF87a files. Transparency and interlacing options are present for
- saving as GIF89a. Interlacing options are present when saving as GIF87a.
-
- There are two methods available for designating the transparent area of
- a GIF89a file. The first is by alpha channel.
-
- 1: Select the portion of the image that is NOT to be transparent.
- 2: Save the selection to an alpha channel using the following menu
- commands: 'Select' 'Save Selection' 'New'
- 3: If you are saving the image as a transparent GIF89a for the first
- time, you will have to use 'Save As' from the 'File' menu. This
- will make the PhotoGIF save options dialog appear. If you have
- previously saved the image as a transparent GIF89a file using
- the alpha channel method, you may simply 'Save' the file and
- PhotoGIF will use the last set options for the file. This way the
- transparent area of the image may be easily changed by editing
- your saved alpha channel and image channel as you would normally in
- Photoshop.
- 4: The default choice in PhotoGIF's save options dialog, if an alpha
- channel is present in the image, is the alpha method and the default
- alpha channel is #2. If the alpha channel you wish to use is different
- you will have to type the channel number into the edit text box. Any
- channel from 2 to 16 may be used in Photoshop 2.5.1, however,
- in Photoshop 3.x the alpha channel must be #2 and the option to save
- as " PhotoGIF" will be disabled if the image file has
- more than one (#2) alpha channel. All alpha channels will be discarded
- when you close the file, but PhotoGIF will create an alpha channel mask
- for the transparent area of all transparent GIFs it opens. This in effect
- is the same as your alpha channel you are using for transparency being
- saved with the image.
- 5: If you also want to save as interlaced, the default choice, just click
- the "Yeah, sure..." button. If you do not want to save as interlaced
- uncheck the option for interlaced first.
-
- The second method for designating the transparent area of an image is by color
- picker:
-
- 1: If you are saving the image as a transparent GIF89a for the first
- time, you will have to use 'Save As' from the 'File' menu. This
- will make the PhotoGIF save options dialog appear. If you have
- previously saved the image as a transparent GIF89a file using
- the color picker method, you may simply 'Save' the file and
- PhotoGIF will use the last set options for the file.
- 2: If there are no alpha channels in the image file the default choice
- will be by color picker. The default color is that of the top, left
- pixel in the image. To pick a different color click on the default
- color in the save options dialog and a color picker dialog will appear.
- Select the color you want for the transparent color and click OK. The
- color picker dialog will close and the color shown in the save options
- dialog will now be the color you picked.
- 3: If you also want to save as interlaced, the default choice, just click
- the "Yeah, sure..." button. If you do not want to save as interlaced
- uncheck the option for interlaced.
-
-
- You may also save a GIF89a image as interlaced without transparency by selecting
- the "None" option from the transparency methods group of radio buttons.
-
- We have added support for interlacing to files saved as GIF87a, so now the check
- box option for interlaced is available at all times.
-
- You can control the color that PhotoGIF remaps the transparent area to if the
- alpha method is used by entering an RGB color value in the three edit text
- fields that appear when the alpha method radio button is on. This is a new
- feature that was suggested by several of our users. In a browser that correctly
- supports transparency changing this color will have no effect on the display of
- transparent images, but it can be used to preserve the background color of your
- Photoshop documents.

-
- Where To Find Additional Documentation and Help
-
- More extensive documentation on PhotoGIF can be found at the PhotoGIF homepage
- in the online manual section URL: http://www.aris.com/boxtop/PhotoGIF/manual.html
-
- It is much more detailed and contains many screen shots, which we hope our users
- will find to be a useful addition to the PhotoGIF homepage.
-
- Technical support is available by email to boxtop@aris.com to both unregistered
- and registered users. Telephone support is also available to registered users of
- PhotoGIF.
-
- We have tried hard to anticipate and answer questions about PhotoGIF, but if you
- have a question that is not answered in the documentation please don't hesitate
- to email it to use. Every question gets an answer. We try very hard to make sure
- that PhotoGIF is the best supported shareware application on the market.
