What is the minimal difference in RGB color values which Mathematica renders and exports as different colors?
I was amazed when I found that Mathematica gives True for the following code (on 32 bit Windows XP with Mathematica 8.0.1):
Rasterize[Graphics[{RGBColor[0, 0, 0], Disk[]}]] ===
Rasterize[Graphics[{RGBColor[0, 0, 1/257], Disk[]}]]
What is the…

Command-line arguments of Mathematica Kernel and FrontEnd
I still know nothing on usage of such command-line options of MathKernel as
-lmverbose
-run cmd
-password "pw"
-pwfile "file"
How are they working and what they are needed for?
Are there other potentially useful command-line options of the…

How to redefine FrontEndEventActions?
Good day,
This question comes from the question on aborting evaluation of the full sequence of inputs.
I think it is probably possible to achieve the desired behavior by redefining FrontEndEventActions for two events: "EvaluateCells" (or pressing…

Controlling the Rasterize[] width for notebook-related expressions
Update Mr Wizard's answer gives pixel-perfect results, but it is Windows-only and destroys the clipboard contents. My answer should work on any platform, but it's less precise: e.g. it omits In/Out labels. It does allow setting the rasterization…

Why doesn't running ClearAll["Global`*"] from a custom Palette update local variables colors?
I created a custom palette, with an ActionMenu that executes ClearAll["Global`*"]. It performs the desired action, but the frontend doesn't instantly update the colors from black to blue (standard), as it happens when ClearAll["Global`*"] is…

It is known that output expressions are passed through MakeBoxes to turn the graphics expressions into the box language which the front end uses to represent graphics (when $Output has default option FormatType->StandardForm). For example, if we…

How to abort evaluation of a sequence of inputs?
By default pressing Alt+. or calling Abort[] within the evaluation causes abort of the currently evaluating input. But when working in the FrontEnd we usually send to the kernel a sequence of inputs. For example, if we type the following three…
