4.2.2. Format of the .TMT files

To provide Navigator with bitmaps of different sizes for an icon, so that it can select the most
appropriate one depending upon the circumstances, .TMT files are used. A .TMT file is just a
concatenation of .BMP files with an index appended at the end. There are two bitmaps for each icon size, a
color bitmap for the image and a monochrome bitmap for the mask:
Bitmap for icon size 1
Mask for icon size 1
...
Bitmap for icon size N
Mask for icon size N
Index
It is recommended that the bitmaps are square, that is, that they have the same width and height. This
value in pixels, or the maximum of the width and the height, if the bitmaps are not square, is considered the
size of the bitmap.
The format of the index is the following:
4 bytes File position of bitmap 1
4 bytes File position of mask 1
4 bytes Icon size 1
...
4 bytes File position of bitmap N
4 bytes File position of mask N
4 bytes Icon size N
4 bytes File position of the index
8 bytes Unused
4 bytes N = Number of icon sizes
Where file positions are byte offsets from the start of the file, and all quantities are stored as
little−endian integers.
It is recommended that you provide color images of 16 by 16 pixels and 32 by 32 pixels with their
corresponding monochrome masks.
You can use the utility ConcatBmpFiles.exe to assemble .TMT files from individual .BMP files:
concatbmpfiles «result».tmt «icon1».bmp «mask1».bmp ... ¬
