RockPlot2D | File | Export | Raster
or
RockWorks | Graphics | 2D Tools | Export | Raster
Use this program to save an existing Rw2D image in a PNG format. PNG files are a popular raster format because there is no color loss, the files sizes are relatively small, and they are compatible with web browsers.

Step-by-Step Summary
Tips
- Input File (in the Graphics | 2D Tools | Export | Raster program only).
- RockPlot2D File: Click here to select the name of the existing Rw2D file to be exported to PNG format.This file must have already been saved in the RockPlot2D window. See Saving RockPlot2D Images.
- Raster Conversion Options
- Export Format: Click in the PNG button to export as a PNG format file.
- Output File Name: Click to the right to type in the name to be assigned to the PNG file to be created.
- Compression Level: PNG files can be created with varied compression; choose from Low, Medium or High. Generally, the higher the compression, the smaller the file size, but image quality can be degraded. Lower compression will result in slightly larger files, but will assure the best image quality.
- Save Progressive: Insert a check in this box to enable drawing of the image on the screen as it is being loaded in the destination application.
- Transparent: Insert a check here if you would like to choose a color in the image to be transparent, and select the color by clicking in the color box.
- Background: Insert a check here if you would like to select a default background color should there be no background color available or selected in the application in which the PNG image is eventually displayed. Select the default color for the background by clicking on the color box.
- Dimensions Defined By:
- Image Size:
- Image Width (Pixels): Enter the number of pixels for the horizontal dimension of the image. RockWorks will calculate the vertical pixels automatically using the Vertical Exaggeration setting.
- Scale Factor: This setting works in conjunction with the Size in Inches, representing the number of diagram coordinates represented per inch in the diagram. For RockWorks maps that use real world coordinates, this may be an important setting. For other RockWorks images, such as ternary or rose diagrams, this may not be.
- Units: Choose Imperial (Inches) or Metric (Centimeters) as the units to be represented in the scale settings.
- Scale (Units / Inch or Cm): Enter the number of map or diagram units to be plotted per inch or centimeter in the output image. This will be adjusted for the vertical axis based on the Vertical Exaggeration setting, below.
- Vertical Exaggeration Enter "1.0" if the horizontal and vertical axes are to be scaled the same. Enter a value greater than "1.0" for the vertical axis to be stretched; enter a value less than "1.0" for the horizontal axis to be stretched.
- Pattern Scaling:
- Automatic: This option, which is default, will scale any diagram patterns (such as those in cross-sections) automatically, to match the pattern density that you see on the screen.
- Manual: This option can be used to increase or decrease the density of the patterns, particularly if you are exporting at a large vertical exaggeration. The greater the number you enter, the less dense the pattern will appear in the output. If you are compensating for a large vertical exaggeration in a cross section diagram, for example, you may want to make the vertical scalar a smaller value than the horizontal scalar.
- Create "World" File: Insert a check here for the program to create an accompanying World File with the output graphic. Use the following options to define the naming convention.
- Append "W" To Output Extension: Choose this option if the file name extension of the World File should have the output file name extension plus the character "w". Example: If the output image is named "Project 27.png", the World File will be named "Project 27.pngw".
- 3-Character Format: Choose this option if the file name extension of the World File should have 3-characters:
- The first character of the extension will equal the first character of the output file extension.
- The second character of the extension will be equal to the last character of the output file extension.
- The third character of the extension will be set to "W".
- Example: If the output image is named "Project 27.png", the World File will be named "Project 27.pgw".
- Show Output in Default Viewer: Check this box if you want the output file to be loaded into the software on your computer that is currently established (via Windows) as the default program to view PNG files.
- From RockPlot2D: If necessary, open the Rw2D file you wish to export (see Opening Plot Files) or save the current plot if it is untitled (see Saving RockPlot2D Images). Then, select the File | Export | Raster option from the RockPlot2D menu.
- OR -
From the main RockWorks menu: Select the Graphics | 2D Tools | Export | Raster menu option.
- Enter the requested information in the displayed program window, as described above.
- Click the Process button when you are ready to continue.
The program will then store the current plot file in a Portable Network Graphics format. If a World File was requested, it will also be saved, using the requested file name convention. If requested, the PNG file will be loaded into the default viewer you have installed on your computer.
