- Subject: Printing in MacApp
-
- Our application uses MacApp and Quickdraw to display and print maps. The
- boundaries of the various features on the maps, for example the coastline, are
- quite intricate and we would like them to print at the maximum resolution of
- the device. On our HP Paintjet this is 216 DPI, on the Laserwriter it is
- 300DPI. However, when we print to either of these devices the lines come out
- looking like they were printed on an Imagewriter, ie 1/72 inch wide. This seems
- to be because there is no way of expressing a line width smaller than 1
- (screen) pixel in Quickdraw. We note that other small details can be resolved
- on these devices, for example 4 point text is quite readable.
-
- What should we be doing to get TRUE 1 pixel line widths? We know the devices
- can do it. We drive them directly from our VAX-based software and get 1 pixel
- lines.
-
- The last time we asked this question (about 1 year ago) the answer was "look at
- the FracApp300 example" but this is not a very satisfactory solution due to:
- 1. It is in MacApp 1.1 not 2.0B9
- 2. It replaces the entire standard print handler.
- 3. It is very complicated.
- 4. (MOST IMPORTANT) It requires one to transform everything into a bit map.
-
- Isnt there a simpler way?
