SAVESNAP

SAVESNAP
Syntax	`SAVESNAP bitmap filename` `SAVESNAP bitmap filename.ext` `(SAVESNAP bitmap)` `SAVESNAP bitmap []` `SAVESNAP bitmap type-descriptors`
Explanation	SAVESNAP saves a bit map file directly on the disk. SAVESNAP saves graphics images in the format specified in the built-in variable PICTURE.FORMAT. You do not need to include the extension to save the file in the default format. Add the extension BMP or JPG (also PICT on the Macintosh) to save the file in a different graphics format. These images can be viewed with LOADSNAP or LOADPIC. SAVESNAP is also capable of displaying a standard file open/save dialog box. In order to open a dialog box instead of a file, the file name contains a list of file type descriptors. A file type descriptor is a file type, optionally followed by an "=" and a description. The text "JPG=JPEG files" would be a vaild file type descriptor for all files ending with ".JPG". More than one file descriptor may be supplied; in this case, separate the descriptors with commas. The file open/save dialog would display all files ending with the given file type. A Windows dialog would also display the description of the file types, while a Macintosh dialog would display the matching files only. The Logo command SAVESNAP "\|JPG=JPEG files,BMP=Windows bitmaps\| would, for example, display all files ending with .JPG or .BMP. If you use "*" as a file type, the file open/save dialog displays all available files. This is done differently on Windows and the Macintosh. A Windows dialog would initially display all files with the first type, and offer all additional file types as choices. The Macintosh dialog would always display all files matching all file types. If you do not supply a file name, Logo automatically opens a file open/save dialog displaying all graphics images. Clicking the Cancel button in a file open/save dialog cancels the execution of the SAVESNAP command. See also SNAP, SNAPSIZE, and LOADSNAP .
