Choices containing file types of available formats. 0x1319 ∙ 4889
IG_ISIS_TAG_AVAILFORMAT_FILETYPES allows an application to determine the types of files supported by the application. This allows the application to determine the index of each file type so that other strings (such as IG_ISIS_TAG_AVAILFORMAT_NAMES and IG_ISIS_TAG_AVAILFORMAT_EXTS) can be retrieved and displayed in an open or save dialog box. (Read-only.)
IG_ISIS_TAG_TYPE_LONG
PIXFPACK.
The choices for IG_ISIS_TAG_AVAILFORMAT_FILETYPES may contain any of the following values:
| IG_ISIS_FILETYPE_TIFF | TIFF files are available. |
| IG_ISIS_FILETYPE_PDA | PDA files are available. |
| IG_ISIS_FILETYPE_PCX | PCX files are available. |
| IG_ISIS_FILETYPE_DCX | DCX files are available. |
| IG_ISIS_FILETYPE_GIF | GIF files are available. |
| IG_ISIS_FILETYPE_BMP | BMP files are available. |
| IG_ISIS_FILETYPE_JPEG | JPEG files are available. |
| IG_ISIS_FILETYPE_CALS | CALS files are available. |
The choices for IG_ISIS_TAG_AVAILFORMAT_FILETYPES depend on the value of IG_ISIS_TAG_NUMALLOWEDFORMATS and, if IG_ISIS_TAG_NUMALLOWEDFORMATS has a value of other than IG_ISIS_NUMALLOWED_ALL (zero), also on the values of IG_ISIS_TAG_ALLOWEDFORMATS.
IG_ISIS_TAG_NUMALLOWEDFORMATS ∙ IG_ISIS_TAG_ALLOWEDFORMATS ∙ IG_ISIS_TAG_AVAILFORMAT_FILETYPES
The choices for IG_ISIS_TAG_AVAILFORMAT_FILETYPES contain the file type values of the available file types. The value of this tag has no meaning. After obtaining an index value for a particular IG_ISIS_TAG_FILETYPE_name (by using the Windows function LB_GETCURSEL to get the current selection of the file type list box), get the file types by calling IG_ISIS_choice_get_long using this index value in the wIndex parameter.
