Description of Img2Ozf program Fields and Buttons

"Map Conversion" Tab

Fields

Source Map Folder - Use the button on the right hand end of the field to select the folder where the map(s) to be converted are located. The (.map) files will be listed.  If the corresponding image cannot be found, the map file will not be listed.

Destination Folder - The folder where the converted images are saved. The button with the Up arrow will make the folder the same as the Source folder.

Include Image Path - If selected, the full path to the converted image will be included in the map file.

Copy Converted Map To The PDA - If selected, after converting the maps the new map(s) will be transferred to the PDA. (Both the map file and image file will be copied, the original will not be deleted from the PC.)

Note : The PDA must be connected via Activesync to be able to copy maps to the PDA.

Initial Resize - Set the new image size as a percentage of the original image if the checkbox is selected. The resized image will become the 100% image in the OZFx3 file. The last resize setting used will be saved but you must always tick the checkbox if you want the initial resize done. Note: Unless you have a specific requirement to have the image resized the value should be left at 100% for most conversions.

Number Colors - This specifies the number of colors to use in the converted image. You must always make sure the checkbox is ticked if you want the color reduction done.

• Reducing the number of colors gives smaller files as compression is improved.
• If the number of colors specified is too small the image quality will be reduced.
• The minimum number of colors which can be specified is 8.
• Images which have 256 colors or less will take longer to convert as the color reduction function needs to be done. Images which have 16 million colors will take no longer as a color reduction is performed anyway.

In general

• 48 colors will show no significant reduction in image quality (this is the default).
• Less than 48 colors will gradually reduce the image quality until at 8 colors the image quality will be very poor.
• 32 colors seems to be a good compromise if a reduced image size is a requirement.

Note : Some images (especially dedicated mapping formats) already use a small number of colors, so specifying color reduction will have minimal affect on image size or quality, but it will take longer to convert the images as the color reduction function will still be performed.

USGS DRG maps are an example of maps which use few colors.

Map File List - The list of files in the Source Image Folder that can be converted. You can select as many files in the list as required using the "Shift" or "Ctrl" keys while clicking on the image name. The list can be sorted on a column by clicking on the column title. (eg to sort on Image Type, click Type). The list can be filtered using the "Filter" box.
