Exporting files to GIF and JPEG formats for use on the WWW


So. . . what's the big deal with file formats? Jeremy Crampton has a brief overview of the various file formats you will probably encounter on the Web. The following is taken from notes for his Advanced Cartography class (http://geog.gmu.edu/gess/classes/geog411/). If you absolutely must have it, there's more info there.


Exporting to GIF format from Corel*Draw:

Follow these steps to create a GIF file from a Corel*Draw .cdr file:

  2. Under the File menu, select "Export"
  3. Under "List files of Type" choose CompuServe Bitmap, *.gif
  4. select the destination directory and filename, then click OK
  5. In the "export" window,select color, dithered colors, 256 colors, 75dpi resolution, and 1:1 size



Exporting to JPEG format from Corel*Draw:

Follow these steps to create a JPEG file from a Corel*Draw .cdr file:

  2. Under the File menu, select "Export"
  3. Under "List files of Type" choose JPEG BITMAP *.jpg
  4. select the destination directory and filename, then click OK
  5. Use the default JPEG Format and Subformat options. Move the slider bar to select the amount of compression you want. More compression means a smaller file, but also diminished file quality. Click on OK.

Exporting to GIF format from Adobe Photoshop:

  1. Save the drawing as graphic.psd
  2. Under the Mode menu, select Indexed Color
  3. In the window that appears, select other for the resolution and type 256 in the "colors" box. Select Adaptive Palette and either None or Diffusion (your choice) for the Dither mode. Click OK.
  4. Now, select File, Save As, and Compuserve *.GIF as the format type. Enter your file name in the appropriate box, and click on OK.


Exporting to JPEG format from Adobe Photoshop:

Make sure you only have one layer in your graphic. If you've been working with multiple layers (to add text, for instance), you should use the Merge Layers or Flatten Image command on the layers control window.

Select "Save as" from the File pull-down menu and choose "jpeg" as the file type.
