Loading a .bmp File
Select File/Open from the menu, and choose a file with a .bmp extension.
The image is displayed in its own window. The application does not accept
compressed bitmaps or multi-planed bitmaps. If a 24-bit colour bitmap
image is loaded into Osd Creator it will be automatically converted down to
a 256 colour palette.
E.5.3
Creating Transparency
Overview
Each pixel in a .bmp file is represented by a red, green and blue
component, each with a value 0 to 255. Osd Creator adds a fourth
component for the transparency of the pixel. This is referred to as a mix
or transparency (T) value and is displayed in the bottom right status panel.
The transparency component also has a range of 0 to 255, where 0 is fully
transparent and 255 is fully opaque.
