Logo Creator
E-4 1/1553-FGC 101 1790 Uen Y
E.4 Loading a File
Logo creator can load bitmap file or OSD files.
To load a bitmap file Select
File > Open
from the menu and choose a bitmap file
(.BMP extension). The application will not accept compressed bitmaps or multi-
planed bitmaps.
To load an OSD file Select File > Open from the menu and choose an OSD file
(.OSD extension). The application will accept version 2, 3, 4, 5 and 6 OSD files.
The application will then display the image from the bitmap and the palette used in
the image.
E.5 Create Logo Tab
When the logo is first loaded the Create Logo tab is shown, this allows the image
appearance to be changed.
E.5.1 Creating Transparency
We shall call the area of the image that is to be made transparent the inactive area.
The rest is the active area.
Transparency can be added manually or by using a Key File.
A Key File is a bitmap image with the same size as the OSD image. In this file the
inactive areas should be colored white, the active areas should be colored black and
the parts with an intermediate level of transparency should be intermediate levels of
grey.
The settings for changing transparency manually are located on the toolbar at the
top.
E.5.2 Adding Transparency Manually
Firstly, change the background color so that it contrasts sharply with the whole of
the source image, using the black, red, green or blue buttons on the toolbar. This
will make it easier to spot mistakes.
The left button is used to make an area transparent (transparency 0), the right
button makes it opaque (transparency 255). Different transparency levels can be
selected by entering different values in the transparency boxes in the toolbar.
The brush size determines the size of the area that is changed. Small brush size
colors individual pixels, medium brush size colors a circle with a 5 pixel diameter,
large brush size colors a circle with a 9 pixel diameter.
