Thanks. It worked, but it took some experimenting. My first
experiments were in the Indexed Color mode. The magic wand always
crashed the Photoshop. Then I tried Grayscale mode - it worked much
better. I could select all the white pixels, but I could not remove
them, so I selected all the black pixels and I pasted them into a new
layer. This worked much better although I had to spend a minute
aligning the pasted pixels with the rest of the image.

I am trying to make a shading for a patent drawing. The U.S. patent
office does not accept computer renderings of 3D CAD drawings. The
drawings must have only two colors (black and white) and they must be
either hand-made, or they must look like hand-made drawings. This
means that the only way to make relatively nice 3D patent drawings is
to combine 3 layers (lines, shading, text) in the Photoshop or a
similar program. The two top layers must be transparent, so all the
white pixels must be removed.

Here is a list of the service packs from AutoCad LT from 1999:
http://usa.autodesk.com/adsk/servlet/ps/dl/index?siteID=123112&id=2334...&linkID
I assume that's the version you're using. Is that correct - AutoCad LT
from 1999? >> Stay informed about: How can I remove all white pixels? |

Ah, OK that's what you're doing, filling in colors on a monochrome
bitmap. In photoshop the paintbucket might do what you need here... or
not. For future reference, the better tool for this is something like
Illustrator which can import the vector linework from ACAD & apply
gradients & line weights, etc. Also it's going to look better with
anti-aliased edges rather than jaggy forced bitmap edges. Zoom way in on
some text in photoshop & you will see gray pixels softening the edges.
Without those gray pixels it gets ugly.

Photoshop is hard to learn and the help files are indeed a cruel joke.
Video tutorials are a nice way to go, or looking over someone's
shoulder. Simply tinkering will not get you far. I picked it up
gradually over about 15 years time working with people who know the
tricks. ACAD I mostly taught myself, they are *very* different.
Crashing isn't normal: something else must be going on. If the file size
is extremely large and/or too many undo levels are left in memory, that
could bring things to a near standstill but PS almost never crashes in
my experience. >> Stay informed about: How can I remove all white pixels? |

Between 1984 and 1997 I was a sort of living encyclopedia of AutoCAD.
At that time there were usually 3 or 4 annual releases of AutoCAD.
For example: 11a, 11b, 11c, 11d. The "a" release was buggy so I always
ignored it. The "c" release typically came out half a year later. It
was either perfect or almost perfect. When AutoCAD crashes, it
automatically saves the drawing file, so it is not a catastrophe, but
a nuisance. AutoCAD is a professional tool meant for those who are
willing to invest at least a few hundred hours in learning it and
customizing (programming) it. Photoshop cannot be compared to AutoCAD
- it looks and feels like a bonus program bundled on CD-ROM sold for
99 cents. >> Stay informed about: How can I remove all white pixels? |

no doubt it was. photoshop is extremely stable, but when run on flaky
hardware, crashes can occur.

i've used every version of photoshop since before 1.0 was released and
the only times it crashed that i can recall was in version 4 (i think
-- it's been way too long) when saving a jpeg could occasionally crash
if there was not enough memory, or a buggy third party plug-in, which
is not adobe's fault. >> Stay informed about: How can I remove all white pixels? |

A well-known bug in PSE6 is that pressing F1 *doesn't* work!

I typed Special instead of Select.
Open Image
Select Magic Wand
Click on a white area.
Under Select Menu choose Similar
All white areas should be selected.

Why not just convert the image to grayscale, and adjust Levels Output to
eliminate pure white? What am I missing? Where are these white pixels
coming from? Do you have any before and after examples?

That's not you do it in Photoshop. You make the layers
as black and white, most easily by using "threshold" in
Photoshop. Then you just set the layer conversion to "multiply"
and opacity to 100%. Finally, flatten layers.

My own take is that AutoCAD has a much more logical menu system, and
that Photoshop has become less stable with each major release. Case in
point is Photoshop Elements 6, which has way too many painful glitches,
and a black user interface that's downright painful to use.

If your drawings are bitmap-based (bmp, jpg, etc.), there's a
simple way to do what you want with MS Paint -
1. Save each layer as a separate picture
2. Open the bottom layer in MS Paint
3. Choose White as the background color (default)
4. Select "Paste from" from the Edit menu
5. Paste one of the other layers, choosing the transparent
background option (bottom of the tool bar)
6. Paste the third image >> Stay informed about: How can I remove all white pixels? |

Photoshop is a very advanced professional tool. I'm constantly amazed
how many tricks await my discovery, though I'm probably equally amazed
how anyone ever discovers them  >> Stay informed about: How can I remove all white pixels? |
