Description
Format.ExportPrintPreviewToImage Method |
Description
Exports an image for each page of a document's print preview.
Syntax
Format.ExportPrintPreviewToImage(Directory, FileNameTemplate, FileType, Colors, DPI, backgroundColor, SaveOpts, IncludeMargins, IncludeBorder, Msgs)
Where:
Directory is the directory where the print preview images is saved.
FileNameTemplate is the file name template that is used when the file is saved. If the file name template does not contain any variables, the page number is added to the end of the file name. The supported FileNameTemplate variable is %PageNumber%. When %PageNumber% is used, the name of the file is the current page number of the image that is saved. You must also add the file type extension to the file name for the file to open correctly when it is selected. The FileType parameter defines the file type but does not add the extension to the file name.
FileType is the image file type (such as JPG, GIF, and so on). For a list of supported image types, refer to Supported Image Formats in the BarTender online help system.
Colors sets the number of colors that are used to create the image. Available options include BtColors.btColorsMono (black and white), BtColors.btColors16 (16 colors), BtColors.btColors256 (256 colors), BtColors.btColors24bit (24bit color file), and BtColors.btColors32bit (32bit color file). BtColors.btColors32bit supports exporting the object with a transparent background.
DPI sets the resolution of the exported image in dots per inch (dpi). Valid values can be any number from 2 to 3000 or one of the following designated values:
-1 (equal to 1 dpi)
0 (the resolution of the screen that creates the image)
1 (the resolution of the printer)
BackgroundColor sets the background color of the page that displays the preview images. Valid values can be any number (24-bit integer with the least significant 8 bits being red, then green, and the most significant 8 bits being blue).
SaveOpts sets when the file is saved. Available options include BtSaveOptions.btPromptSave (save when prompted), BtSaveOptions.btDoNotSaveChanges (do not save changes), and BtSaveOptions.btSaveChanges (save all changes).
IncludeMargins includes the page margins in the image. When this is set to false, the image is trimmed to the edge of the labels.
IncludeBorder draws a thin black rectangular border around the label when set to true.
Msgs collects and saves any error messages that were created during the export for later review.
