Photoshop 5 Course Part 11
by BarryHilton, Adult NetSurprise
Designing
transparent Gifs in Photoshop This week we are going to design a
transparent Gif using Photoshop's GIF89a export.
| |
First we want to create a new image. Go to the 'File'
menu at the top of the screen and choose 'New' from the menu... From the menu
that pops up enter 50 pixels width, 50 pixels height, and 72
resolution. |

 |
We will use a black background (this is the color we
will make transparent), so change your foreground color to black by clicking
the little boxes on the bottom left of the color selector. Then select the
'Paint' tool from the 'Tool' menu and click inside your image to make your
black background. |
 |
Then add a new layer to your image. Click on your
'Background' layer then click the create new layer button at the bottom of the
'Layers' menu. Double click on this new layer and rename it 'Button'.
|
 |
We will create a round transparent button, so... Select
the 'Elliptical Marquee' from the 'Tool' menu, entering a Style of 'Fixed Size'
and a height, width of 50 pixels and untick (not selected) anti-aliasing in the
'Marquee Options' menu.
Now click inside your image and drag your
marquee to the middle of your image so the marquee edges touch all sides of
your image. |

 |
Choose red from the 'Swatches' menu. Then select the
'Paint' tool from the 'Tool' menu and click inside your marquee to make your
red button.
Now add a bevel effect to our button... Right click on your
'Button' layer and choose 'Effects' from the menu. De-select 'Drop Shadow' and
go to the 'Bevel and Emboss' menu. Enter values for highlight mode 'Screen,
opacity 75%, shadow mode 'Multiply', opacity 75%, style 'Inner Bevel', angle
135, depth 5, blur 5 and 'up' selected.
If you want a more realistic
effect you can change the black color (click the color box) to a very dark
red. |

 |
Now we want to add 'GO' text to our button... We want
our text to be yellow so first select yellow from the 'Swatches'
menu.
Then select the 'Text' tool from the 'Tool' menu. In our example
we are using the 'Arial' font, size 30 pixels and tracking at -100.
Type
'GO' and press OK.
If you need use the 'Move' tool on the 'Tool' menu to
click and drag your 'GO' into the center of your button |
| |
Now we are going to make our button transparent... First
we need to change the color mode of our image. Go to the 'Image' menu at the
top of the screen and select 'Mode' then 'Indexed Color'. On the menu that
appears click OK to flatten your image. Don't forget if you want to edit your
button later save it first as a psd file before changing the color
mode.
Now go to the 'File' menu at the top of the screen, select
'Export' then 'GIF89a'. This will bring up the 'GIF89a Export Options' menu.
The menu will have a picture of your button and all the colors your button uses
separated at the bottom.
Untick (not selected) 'Interlace'. Then to make
your button's background color transparent just move your cursor over the
picture of your button (your cursor will change to a 'Color Dropper') and click
on the black background of your image.
Then Click OK to save your
transparent Gif! To see our example
click
here.
You can also use this to make transparent text, just make sure
that your text has 'Anti-aliased' unticked and turned off!!! |
