These options determine how PMView saves OS/2 Pointers.
Pointer Format
OS/2 2.0 This will save the pointer with a header that is compatible with OS/2 version 2.x and above.
OS/2 1.2 This will save the file with a header that is compatible with OS/2 version 1.x and above.
Size This lets you select the size of the pointer. Pointers saved by PMView are always square (see the note below), so the value you set here will represent both the width and height. For instance "32" means that a "32x32" pointer will be generated.
Color Type This lets you select the color depth and palette type used for the pointer.
Black & White This will save the pointer in black & white.
16 colors, Adaptive palette This will save the pointer with 16 colors. This will select the best colors for the pointer.
16 colors, System palette This will save the pointer with 16 colors. The pointer will only use colors in OS/2's system palette.
256 colors, Adaptive palette This will save the pointer with 256 colors. This will select the best colors for the pointer.
256 colors, System palette This will save the pointer with 256 colors. The pointer will only use colors in OS/2's system palette.
Deep color (24-bit) This will save the pointer with full color information.
Transparent Fill If set, the unused area of the pointer will be made transparent. If not set, the unused area will be black.
Use RLE/Huffman1D Encoding If set, PMView will RLE or Huffman1D encode the pointer data. The pointer mask data will be Huffman1D encoded. This alone will typically reduce the size of the file by almost 25%. Further compression is achieved if the image contains large areas of the same color. Note that not all programs are able to cope with Huffman1D encoded data and thus cannot read pointers saved with this option.
Note ICONEDIT, the icon editor shipped with OS/2 Warp is not able to handle all variants of OS/2 pointers. Any and all of the following options should be avoided if compatibility with ICONEDIT is desired:
Icon Format: OS/2 1.2 (ICONEDIT will refuse to load the pointer)
Color Type: 256 colors, Adaptive palette (ICONEDIT will crash)
Use RLE/Huffman1D Encoding: On (ICONEDIT will display garbage)
Note PMView always saves square pointers. A pointer can be non-square, for instance 20x32, but this is not useful in practice. One example of this is that the OS/2 Workplace shell will stretch the pointer to 32x32 (or 40x40) and thus distort the aspect ratio if the pointer is not square. However, if you find any use for non-square pointers and would like PMView to be able to generate such pointers, please let us know and we will add this capability.
