There are a few changes since version 1.5 that have not made it into the documentation yet:
The program is now at least twice as fast version 1.5 in all its operations.
The program can now can create databases that cross the 180 degree meridian. Click and drag on the world map in the main window. When you get to the East or West edge the map will scroll.
Multiple undos have been added. Every change to the boundaries is remembered. Use Command U to undo, and Command R to redo.
RESOLUTION EDIT FIELDS:
Three new edit fields have been added to the "Export file info" section of the main window. The 'Width', 'Height' and 'Rez' fields work as a resolution calculator. They provide information about the resolution of the exported file. The four radio buttons above the edit fields labeled "in.", "pts.", "pi." and "cm" set the units of measure: "in." is inches, "pts." is points, "pi." is picas and "cm" is centimeters. One of these fields is always locked, as indicated by the little lock icon to the right of the fields. The other two are unlocked. Clicking on one of the unlocked icons will lock it, and unlock the others. As you make changes to the boundaries and scale of the map the locked edit field remains unchanged and the two unlocked edit fields are recalculated. This resolution information is only saved if you save a tiff file. When saving a Geocart database, the resolution is not saved. Geocart database format does not include this type of resolution information.
COPY GTOPO FILES TO YOUR HARD DISK
TopoToImage will now remember where the Gtopo files are if you copy them to another hard disk. Copy all the Gtopo files to a single folder. The first time you use the files the program will ask you to locate the folder. After that the program will remember where they are. Note: TopoToImage keeps track of the location of files by storing a copy of the complete path to the files. This path name can only be 256 characters long.
GRADIENT DESIGN WINDOW CHANGES:
Three new effects have been added to the Gradient design window: 'Hue', 'Saturation' and 'Lightness'. When you click each of these buttons a small window with a slider control will open. These controls will change the colors on the gradient bar. The 'Hue' button will rotate the hue of the color between -180 and 180 degrees. The 'Saturation' button will saturate or desaturate the colors. And the Lightness button can be used to make the colors lighter or darker. You can change all the colors or just the current color by clicking on the appropriate radio button in each of these windows
DRAG AND DROP COLORS
down the Option key to drag and drop colors between the color chip and
the gradient color. Colors can be quickly copied between the points
on the gradient bar and the other color chips.
