Didger 4 includes the astounding capability to automatically digitize polylines and polygons in an image. This time saving feature often provides better digitized images than manually digitizing. Three very common uses of the Vectorize Imagecommand are automatically digitizing logs, graphs, and contours. The quality of the image and the number of colors in the image will determine the effectiveness of the Vectorize Image command. Pre-processing the image using the filters under Image | Processing Filters and/or modifying the settings in the Vectorize Image dialog box may help get better results. Image Processing Options: Image pre-processing is a good option to consider when working with 24-bit images or when the vectorization results are less than expected. True color images can create potential problems in vectorization, since the individual pixels making up what looks to be a solid color, can in fact vary in color. This could cause the pixels to end up being disconnected and result in poorly formed lines. It is generally wise to create an image with the least number of colors necessary and formatting the lines to vectorize as solid as possible for the vectorization process. Specific Case Examples: Below are some specific examples of images and tips you can use to automatically digitize them more effectively: If there is no color difference between the lines in a graph, the axis, and the grid lines (they are all black lines), using the Vectorize Image command may not work very well. You can try either erasing the extra markings using software like Adobe Photoshop or manually digitize the lines in Didger using the Digitize | Polyline command. With some images, manual digitizing will still be the best solution. This a great program. I've been an ardent user since the early, text driven, DOS versions. How any geologist or geophysicist manages without it I don't know...James Moffatt, Principal Geoscientist, Tullow Oil I very much like working with Golden Software. I find the software very easy to use and very helpful.David Orr, Shrimp Biologist, Fisheries and Oceans Canada Enter your email address below to receive email notifications of product updates and our newsletter, filled with helpful technical tips and case studies Copyright © 2016 Golden Software, LLC.
