Tech Tip: Printing a Multi-page TIFF File

Snowbound Software’s RasterMasterTM for the .NET Platform includes the ability to print multi-page file formats such as TIFF files. You can use the C# code sample below to print a multi-page file.

/**********************************************************************

;PROGRAM: PrintForm.cs

;

;PURPOSE: Printing and preview sample.

;

;This is example code for all SnowBound customers to freely copy and use

;however they wish.

;

;LIBRARY FUNCTIONS USED:

; Snowbnd() - Init Snowbound component.

; CIMG_decompress_bitmap() - Load an image from disk.

; CIMG_display_bitmap - Display image.

; CIMG_print_bitmap - Print the image.
