Dear Colleagues:
I have been searching for an electronic overlay font (preferably a
Microsoft compatible "True Type" variety rather than an Adobe "Post
Script") to facilitate labeling of gray-scale images. Is anyone aware of a
source for such work saver?
In the pre-digital days, we were getting good results with the paste-on
overlay letters that are still available from microscopy supply houses
(e.g., I was partial to the Microscopist's Collection from SPI). These
were the little black letters that were printed over slightly larger white
outlines. Because of this contrasting outline, they were easily readable
irrespective of the brightness of the image below.
Currently, we are barely getting by in labeling of electronic images by
adjusting the font color to either white or black, according to what the
brightness of the underlying image dictates. More often than not, this is
ineffective in EM images with highly modulated brightness. On occasion, I
have resorted to manually overlaying a black text over a white one in a
bold version of the same font; this is tedious and does not work in all
but the briefest annotations because the kerning of the two font styles
does not compensate for the differences in the widths of the letters.
The simplistic solution of setting the overlay text box background color to
non-transparent is not satisfactory because it often ends up obscuring the
feature of interest.
Does anyone possess a suitably outlined font, or has come up with a
creative solution to this vexing problem?

One solution is to import your image files into
Microsoft Word (other word processors may have
similar functions) and use the WordArt tool
to overlay your picture with the desired text.
This tool will allow you to outline letters using
most true type fonts and allows you to control
pitch, text color, outline color, and outline thickness.
This method is fairly quick and painless. One
hint is that when you first start adding text
it may disappear behind the image. To bring
the text to the front click on the image with
the second mouse button, click on "order" and
select "send behind text". This will place the
image behind the text so that the text remains
visible.
You can then either save the image in Word format
or use a screen capture program to save the image
in other formats. If using a screen capture program
(such as LView) you will be limited to the resolution
of your screen minus window borders so this solution
works only for smaller images (aprox. 970x570 pixels
on a 1024x768 monitor). There may be a way to export
larger images from Word but as I am a novice to using
Word I haven't found one yet.

I should have added that using Word you
can rotate your labels and add arrows,
circles, boxes, etc. to your images.
You can even add cartoon balloons
and let your subjects speak to you.

There is a software package called "Designer" it
is sold by Micrografx. It is very powerful and
will do what you need. The cost is about $600. It
is worth while to check it out.

tool so that the letters are surrounded by marquees when you are done typing.
Type your text on the image. Before you de-select the text, go to the pallette
region of the toolbar and exchange foreground (usually black) and background
(usually white) colors. Then go to the "Edit" menu and select "Stroke" chose a
2-3 pixel stroke width "outside" the letter. This makes an outlined text in any
font on your system.

markers, text, and symbols onto micrographs. The results look just like the
rub-on transfers that I used to use.
1. create a layer (Photoshop 4.0 does this automatically with text tool)
You must use Photoshop image mode for the layer option.
2. in that layer in the font and font size that you want, type the text.
add a black line at an appropriate length and width and any other text,
symbols, arrows, etc. that you want to put on the micrograph. By using the
layer, you preserve the original micrograph in the background layer. you
can use the info window to draw lines to particular lengths. If other
layers are created when new text is added, merge those layers. Don't merge
them with the background layer!
3. Select all (ctrl-A in the PC) The marquee will be around the whole
layer.
4. You have to move the selected region up then down with an arrow key.
(This is done in the PC with the Ctrl-shift-arrow key in the PC) what this
does is to select all of the objects in the layer individually. A Marguee
should be around each object.
5. Select the foreground color as white. (You are going to write a white
border around each Marquee.)
6. Go to Edit-Stroke and select the width of the white line you want (Width)
and select the Outside option. for 300 dpi images at about 4" x 5", I
suggest a font size of about 14 (Arial) with a Width of about 3-4 pixels for
the stroke width. This will write a white border 4 pixels wide around all
of the selected black features.
7. Deselect (ctrl-D)
8. If you want to save this as image in another format such as TIF or BMP,
then you have to Merge the layers and save the image in that mode.
Note: you should have anti-aliasing selected for all this.
This technique works very well for me. You can make them look like real
Rub-ons with another technique and offsetting the white a little, but that
is another story.

assume that PhotoShop also would have that eature. you could chose the
amount and direction of shift of the shadow. I think the colors were also
cusomizable.
However, I don't have acopy of either very accessible just now. For as much
as it comes in handy, I can't imagine such a feature being dropped.

there is a huge variety of text/drawing tools and little
constraint on the size/resolution of the image file? You can
do composites, layouts, cutouts, masks, etc. quite handily.

enables you to make an outline around your letters in a contrasting colour.
So we can have black letters with a white minimal outline or vice-versa.
It works with any typeface. And of course you can make the text any colour
or shade of gray.

However, I just bought a package of plugins for use with Photoshop or Corel
PhotoPaint. The package from Xaos
(http://www.xaostools.com/products/index.html) cost $129 and included:
TypeCaster, Paint Alchemy and Terrazo. The TypeCaster plugin will enable you
to create highly visible text on your micrographs--it may be difficult to
restrain your creative impulses. The other plugins may be useful for
creating backgrounds for slides, web page images and as simple relief from
the humdrum of scientific data.
I have no connection with Xaos financial, social or otherwise--wish I did!
