The image processing examples explain how to use built-in functions to manipulate image files. To visualize the resulting image, the examples use the WRITEBMP function to save the results to a BMP file. PTC Mathcad writes the BMP files to the current working directory. To view the current working directory, type CWD=

When you copy an image processing example from a Help page and into a worksheet, the BMP images are not copied automatically. Your worksheet shows the pasted example with these BMP images missing. The image file name, however, appears below each missing image. To make the images part of your worksheet, browse for the image name in the folder that contains the example data files and insert each image at the point where it should appear in the original example.
