- First, I wish to thank Mr. Ed Kallen (mughi@netcom.com) for his graciousness
- in posting the ASCII file of the photo of Ms. Kizaki in the ohuro. I enjoyed
- it very much; at least, I can now see what I'll never get ... (Never mind.
- It's my own cross to bear--between me and my God, who probably hates me
- anyhow ...)
-
- Anyways, I do have some questions. First, I am running the xloadimage
- command on a Sparcstation 2, which can be assumed to be equipped with
- the minimal set of hardware. It is really _only_ equipped to display images
- of VLSI circuits designed in Magic.
-
- My system has no built-in xloadimage command; apparently, the system
- administrator decided to leave out. So, over the break, I ftped xloadimage
- source code from export.lcs.mit.edu, hacked on it, and compiled it into
- something that _apparently_ works.
-
- I used it to display bepp-10.jpg (the photo of the lovely Japanese lady).
- Here's what I typed:
-
- xloadimage bepp-10.jpg
-
- The system pops back:
- (1) bepp-10.jpg is a 464x768 JPEG Image, color space YCbCr, 3 comps., Huffman coding
- (2) Converting true color image to RGB image with 256 colors...image uses 874 colors...done
- (3) Using private colormap
- (4) Building XImage...done
-
- Unfortunately, the quality of my image is only average, but I've noticed
- that some other non-English speakers here seem to be able to produce a
- higher quality image. So, I must be doing something wrong, at least in my
- compilation.
-
- Question #1
- -----------
- Line #1 of the response seems okay. However, Line #2 seems to suggest that
- my maximum number of colors is 256! How can this be? I thought that
- Suns were equipped with a display capability of at least 1024 colors even
- in the base model.
-
- Clearly, something screwy is happening. The original picture had 874 colors,
- but they have been mapped into 256 colors! How can I expand my capability
- to 1024 colors (or, at least 256 colors)? Did I do something wrong in the
- compilation of my code? What paramemters must I set to release the
- full 1024 colors?
-
- Question #2
- -----------
- What is Line #3 referring to? Where is the "private colormap"? How can
- I access it?
-
- Question #3
- -----------
- Could you describe to me the graphics capabilities of the base-model
- Sparcstation #2?
-
-
- When you reply, please send e-mail. I'll post a summary.
