- Item 2728670 1-May-90 01:00PDT
-
- From: RANSON France - Dev, Ranson Lannion,IDV
-
- To: MACAPP.TECH$ MacApp Technical
-
- Sub: THE MacApp book
-
- I've (almost) finished reading the book "Programming with MacApp", and I must
- say that, though the first chapters didn't look very promising, most of it is
- VERY interesting. My favorite is the chapter on streams.
- My main regret is that it seems the authors have not taken the time to read
- their own book! They would have found many typos and incomprehensible pictures.
- Look for instance at figure 13-5 representing the three highlighting states. On
- my copy, I can see no difference between the three states!
- I have found something that looks to me like a misconception of the Quickdraw
- printing model (well, maybe I am mistaken...). At the bottom of page 440, there
- is this small computation: considering that QD coordinates are limited to about
- 32000, and the current maximum printer resolution is 300 dots per inch, the
- maximum QD view size is about 32000/300 inches.
- I had always thought that whatever the physical device, drawing in a QD port
- with QD traps (NOT PostScript QD comments) was always done at 72 dots per inch.
- And when I draw a 72 points line, I expect it to be 1 inch long, on any printer
- (WYSIWYG?). Am I wrong?
- Daniel.
