Palette Reallocation
When the level of transparency of a pixel in the image is changed, a new colour is effectively
created. Whenever the image is downsampled or saved, the palette is rebuilt to reflect the
actual colours in the image. As part of this process, pixels which have a mix value of zero are
mapped to palette entry zero, which is defined as Red = Green = Blue = Mix = 0. The original
colour information is lost and the right mouse button will not change the pixel back to its
original colour.
To rebuild the palette during editing, click the Reallocate Palette toolbar button.
D.5.4 Downsampling
Click the Downsample toolbar button. A dialog box appears asking for a downsampling ratio.
This can be specified directly, or by entering the desired image size. Click OK to downsample
the image. The downsampling algorithm includes a filter, so the boundary between the active
and inactive areas softens slightly. Zoom in and check that the correct areas are transparent,
and make corrections if necessary.
NOTE…
Once the image has been downsampled, the process cannot be reversed to change the image back to
its original size.
D.5.5 Saving the .osd File
Select File/Save As/OSD file from the menu. Saving is possible at any time, and it is
advisable to save the image often while editing is in progress. The file may also be saved in
.bmp format, but this file will not contain transparency information.
