comment CMYK colours in a graph template
@keystonethewizard You can insert CMYKColor calls into the Graphics[] expression that draws the arrow-heads...

@MikaIke that's Stefan, not me...perhaps you can delete your comment and try again?

@uka something similar here which could be easily adapted. Look up Locators too, for mouse input.

@MikaIke I added your picture to the question which clarifies it a lot.

comment Plotting data with ListPlot where the coloration of the data depends on its position in an array?
ColorFunctionScaling -> False will pass the unscaled x coordinate of the point to the colour function (I think).

comment Why does saved graphic not look the same as graphic in notebook?
@hypergroups Save Selection and Save Graphics are different, apparently - m_goldberg and I have the same environment....

comment Exporting a sequence of graphs as video efficiently
@VincentTjeng "A watched export never completes" as my grandmother would have said... In hindsight I needn't have generated each frame at 6000 pixels resolution.:)

@VincentTjeng So far my record for generating a movie was 27 hours for about 5 minutes of output... :)

comment Crash when displaying / rasterizing graphics with textures at high resolutions
@nikie Judging from some of the questions here, there's an interesting comparison between Windows-only problems and Mac OSX-only problems (not to mention Linux-only problems). Must be hard to write 100% platform-independent code...

comment How do you export the result of a RevolutionPlot3D to STL for printing?
Good one, Vitaliy! Notice that STL files don't have dimensions or units, so at one point in the submission process for many 3D printer services you have to specify what that -1.0 to 1.0 size signifies - meters, inches, or millimeters, for example. If you know in advance what you can specify, you can scale the graphic suitably.

comment Exporting a sequence of graphs as video efficiently
I've found some advantages to the ffmpeg method: you can fix errors/regenerate single frames, there's more control over output formats, if you get a powercut or a crash you can start again from where you left off, you can more easily monitor progress, and so on. But video is so processor-intensive anyway; just fire it up and go for lunch! (Some individual frames for Toy Story took 30 hours to render...)

For me, Save Selection As... (on cell bracket) saves a rotated image, as does Export. Only Save Graphic As... saves the image without the rotation.
