Getting Started with embossing
Embossing requires a bitmap-object selected. For best results convert
a color-bitmap to gray tones with
Extras->Color Reduction->256 greytones. Then select
Extras->Bitmap effects->Emboss.
For all samples below we are assuming follwing values:
Alpha=20, Direction=30ø, Elevation=45ø. Check the Extras-page
in the Settings-notebook.
- Embossing with an "elevated"-effect.
Set the Direction-parameter to a value between 0-180 degrees.
Alternatively (for ex. with text), make the foreground-text darker as the
background. The samples below illustrate this operation.
- Embossing with a "depressed"-effect.
Set the Direction-parameter to a value between 180-360 degrees.
Alternatively (for ex. with text), make the foreground lighter as the
background.

Embossing sample 1
We'll create a bitmap object from a text-object in two versions, once with a
white background and once with a grey background, apply a texture, and finally
emboss both images.
- make sure we have a clean drawing area. Click on New
on the upper-left icon if necessary.
- Select the text-tool from the toolbar, place the cursor or "T"
in the midddle of screen and click once with the left-mouse button.
At the prompt enter "WORKSHOP". With the TAB-Key leave the field,
and change the Font to "Times Roman Bold". Set the
point size to 40. Now press the CTRL-Key and right-mouse button to get
the selection-tool again. Not doing this may create another text-object,
which you want to delete. Finally change the color of the
text to a dark-tone gray.
- We're almost ready for creating a bitmap of our text-object. We
could just select Bitmap->Crop to bitmap, but we want the
area of the bitmap to be bigger as the area of the text. Select the
rectangle-tool and create a rectangle which is on all sides bigger than
the text-object. Click twice with the left-mouse button to create the
reactangle, and make it fillable. Change the color of the
fill to white. The rectangle will be completely covering the text-object.
Select Edit->Bring down or click on the Bring-down-icon on the
actions-bar. The rectangle should be still selected, the text "WORKSHOP"
should be visible.
Select Bitmap->Crop to bitmap. You
should have following bitmap:
Before applying embossing, we will apply the texture below. Download the
texture to your harddisk for trying the sample yourself, or use a similar one
from the os2/bitmap directory. Import the bitmap into LogoArt and
set it as texture. If you are not sure about this step review the chapter
on textures first.
- We are ready to combine both bitmaps. Mark the target-bitmap (bitmap
with the work "WORKSHOP") and make sure texture.gif is unmarked.
One more step: go to settings-notebook, Extras-page and check
that the alpha value for Bitmap texture is set to 20. Change that
value if necessary and close the panel.
Select Extras->Bitmap effects->Texture (bitmap texture) from the main
menu. Apply the texture twice. Here are the results:
- We apply embossin now:
Select Extras->Bitmap effects->Embossing:
Of course, we could have left out the texture-step, however to get that
"ripples"-effect on the text, applying a texture first is very handy.
- We have one last step left: to save the final result. Select
Bitmap->Save bitmap file.. to get the file-dialog and enter a
name of your choice for the new bitmap. Of course, you could save in this
manner each bitmap created on the steps before (I do actually). Even more,
I create a copy of the bitmap before applying an effect - there is no
undo for special effects.
If you attempt to save the art-file itself now,
LogoArt will complain if you don't save any modified bitmap explicitely.
The next sample demonstrates the opposite effect with embossing: the text
will appear kind of depressed.
-
Embossing sample 2:depressed
This is the second version of a our sample to demonstrate the opposite
effect with embossing: the background in this case is grey and the text
white. If you want to save a bit of work then just copy the previously
saved art-file to emboss2.art for ex., load it and delete all objects
but the rectangle and the original text-object. In this case make the
text white, and the rectangle below gray. Skip the next two steps.
- make sure we have a clean drawing area. Click on New
on the upper-left icon if necessary.
- Select the text-tool from the toolbar, place the cursor or "T"
in the midddle of screen and click once with the left-mouse button.
At the prompt enter "WORKSHOP". With the TAB-Key leave the field,
and change the Font to "Times Roman Bold". Set the
point size to 40. Now press the CTRL-Key and right-mouse button to get
the selection-tool again. Not doing this may create another text-object,
which you want to delete. Finally change the color of the
text to white.

Compare it to the first sample above:
- We have one last step left: to save the final result. Select
Bitmap->Save bitmap file... And save the art-file itself.
-
Embossing sample 3: miscellaneous
With this sample we'll demonstrate applying a color texture to the
bitmap above (ws6.gif).
- make sure we have a clean drawing area. Click on New
on the upper-left icon if necessary.
-
Import the bitmap ws6.gif from the previous sample.
-
We will now create a dithered texture as follows:
- select the rectangle tool.
- Create a small rectangle about half the height of the bitmap
above (width = twice the height), and make it fillable with an orange-tone
(R=255, G=127, B=0). Click once on the selected rectangle and select
from the color options dithering top to bottom. Make sure
the color-flow has a good contrast - if necessary enter 2 for the step
-parameter.
- make a copy of the rectangle and change the dithering to
bottom to top. Now put both rectangles together such that the
bright-tone is in the middle. The height of both rectangles together should
be about the height of the bitmap above.
- Click on Bitmap->Select region and pick the rectangles we
just created. Enter ALT-c to put that region in the clipboard. Paste
the newly created bitmap with Edit->paste from clipboard. You
should have follwing bitmap, which we will use as texture:
- Mark the bitmap in the step before and select
Extras->Set bitmap as texture.
- We are ready to combine both bitmaps. Mark the target-bitmap (bitmap
with the work "WORKSHOP") and make sure orange.gif is unmarked.
Select Extras->Bitmap effects->Texture (bitmap texture) from the main
menu. Apply the texture three times (assuming alpha value = 20).
Here are the results:
- The next sample applies to the bitmap before a new texture
(paper.bmp on the os2/bitmap directory).
