[comp.sys.mac] How to work at 300dpi?

heberlei@iris.ucdavis.edu (Todd) (08/08/89)

I am interested in drawing an image at 144, 216, 288, or 300dpi and
then printing it.  

For example, I am interested in opening a standard
PICT file, and scaling all drawing commands before drawing to a
bitmap.  The command sequence MoveTo(10, 20) LineTo(25, 25) could be
translated to MoveTo(40,80) LineTo(100, 100).  I could then do my own
manipulation to the bitmap, and then save it or print it.  I want the
image to be printed onto a single sheet of paper (at 288dpi or
300dpi).  Thus a PICT file which has a circle that take up half the
page at 72dpi should should be converted to a 300dpi format with a
circle that still takes up half the page.
      PICT -> my_prog -> 300dpi file -> manipulate -> printer

I also have a 3D scan line program that I would like to use in this
manner.

I have Cricket Paint which will allow me to work with an image at
these resolutions, but I do not know how to create my own file in the
Cricket Paint format.  DOES ANYONE KNOW HOW TO CREATE A FILE IN THE
CRICKET PAINT FORMAT (300dpi)?

A second option might be to use the TIFF format, but I have never
worked on Cricket Paint with a TIFF file.  HAS ANYONE WORKED WITH TIFF
IMAGES AND CRICKET PAINT?  WHAT RESOLUTION DOES IT DISPLAY THE IMAGE?

I have a $50 SuperPaint option (from my Word 4.0 purchase), so if I
can get any answers to the above question for *SuperPaint* instead of
*Cricket Paint* I may go this way.

I would greatly appreciate any comments, suggestions, ideas, or even
code.


MANY Thanks,
