ImageJ's fonts

[panovr]

Hi,
  I run the "Fonts.txt" macro, and get a list of available fonts. However,
in ImageJ's menu command "Edit->Options->Fonts...", there are only 5 fonts
can be selected. How to use the available fonts in ImageJ?
  Thanks!

The font.txt macro demonstrates the getFontList() macro function.
The fonts listed by this function are possible arguments to the  
setFont() macro function that sets the font used by the drawString()  
macro function.
Thus, so far, extra fonts can only be used from within a macro, and  
can not be used by the Text tool from the tool bar. This tool uses the  
font set by the Edit/Options/Fonts... dialog which displays only 5  
fonts.

For some reason, the macro gives an error half the way through when showing
all fonts:

I traced it down to a PostScript Type 1 font called "Cursor, Medium". which
seems to return the wrong dimensions.

I added a line to the macro so skip the font if the name is "Cursor".

I also wanted to suggest the following.
The New Image IJ command and the newImage macro command can have a "Black",
"White" and "Ramp" options.
It may be useful to add a "Foreground" and "Background" options which fill the
images with the current foreground or background colours as set in the colour
picker.
Since some (me included) set the default IJ with a black background and a
white foreground, the Fonts macro assumes the opposite and so the result is
all white (you can't see the fonts which are written in the foreground colour
(currently white), with the background assumed to be the IJ default white).
Having "Foreground" and "Background" (in adition to the Black, White and Ramp)
would avoid this kind of problem.
 
Cheers,

Hi there,

I´m just wondering, is there already a plugin that can simulate resp.
compensate for lense distortion in images?

More mathematically, what is needed is the ability to do "warping" on an
image, i.e. remapping pixels to slighly different coordinates, in the case
of lense distortion given  by a radial symmetric function
that in not completely linear in r?

Any functionality built in one could use to do this quickly?

Thanx

Joachim

This is fixed in ImageJ 1.37g, due by the end of this week.

hello,

I'm trying to use the wand tool to select multiples ROI (shift +  
click) in a thresholded image. It seems to work (the ROI are  
outlined) but the "analyse particles" command detects nothing. I have  
tested it with the same measurements settings but with the other  
tools (square, circle) and it works perfect... why ?
Multiple selections are not available with the wand tool ?

Thank you !!

Leon

It appears to work okay if "Exclude on Edges" is not checked in the
Analyze Particles dialog. If it is checked, all particles are excluded
because they all touch an edge.
