Limit choices for IG_ISIS_TAG_AVAILFMTS. 0x1322 ∙ 4898
IG_ISIS_TAG_ALLOWEDFORMATS limits the available formats reported by IG_ISIS_TAG_AVAILFMTS when used with PIXFPACK, allowing your application in a file open or file save dialog to list only a subset of the formats supported by the installed group of file filters (PXIs).
IG_ISIS_TAG_TYPE_LONG
PIXFPACK.
| IG_ISIS_FILETYPE_TIFF | Allow TIFF files. |
| IG_ISIS_FILETYPE_PDA | Allow PDA files. |
| IG_ISIS_FILETYPE_PCX | Allow PCX files. |
| IG_ISIS_FILETYPE_DCX | Allow DCX files. |
| IG_ISIS_FILETYPE_GIF | Allow GIF files. |
| IG_ISIS_FILETYPE_BMP | Allow BMP files. |
| IG_ISIS_FILETYPE_JPEG | Allow JPEG files. |
| IG_ISIS_FILETYPE_CALS | Allow CALS files. |
The number of times IG_ISIS_TAG_ALLOWEDFORMATS can be called depends on the value to which your application sets IG_ISIS_TAG_NUMALLOWEDFORMATS. If IG_ISIS_TAG_NUMALLOWEDFORMATS is set to IG_ISIS_NUMALLOWED_ALL (zero), then all values set by IG_ISIS_TAG_ALLOWEDFORMATS are ignored.
IG_ISIS_TAG_ALLOWEDFORMATS must be set one per IG_ISIS_tag_set_long call, using an index value derived from IG_ISIS_TAG_NUMALLOWEDFORMATS. For example, if you want to allow five formats, you would set IG_ISIS_TAG_NUMALLOWEDFORMATS to 5, and then set IG_ISIS_TAG_ALLOWEDFORMATS five times, using consecutive index values of 0 through 4.
