Victor Image Processing Library How-to Tips

Create a Document with Text and Graphic Images

Begin by initializing the printer, print each image, create the fonts for the text and print each block of text. Eject the page. The images and text are printed into rectanglular areas of the page. The image rectangle is specified in mils (1/1000s of an inch) and the text rectangle is specified in device pixels.

Print a document containing an image and text - the Source Code

This function prints an image in the upper left corner of the page and text in a column to the right of the image. The text is a NULL-terminated string of characters. Requires Victor Image Processing Library for Windows v 4.1x or higher.
