> Once NETBEANS-2604 is done, we should start replacing commonly seen NetBeans 
> icons with SVG versions, for improved appearance on Retina/HiDPI displays.
> With some practice, it takes on average 30 minutes to create an SVG version 
> of a typical icon in Adobe Illustrator. See the attached illustration and 
> Illustrator template. The Illustrator template includes a few icons which 
> have already been converted.
> In NETBEANS-2605, the following prioritized list of icons to convert was 
> produced:
> https://people.csail.mit.edu/ebakke/misc/netbeans-icons/prioritized.html
> By redrawing the most commonly seen icons first, we can get the greatest 
> "bang for the buck" in terms of improving NetBeans' appearance on HiDPI 
> displays. Note that in cases where an icon file has been copied around to 
> various places in the NetBeans codebase, only one of the paths is shown in 
> the list above.
> See also the overview page for HiDPI improvements on 
> https://cwiki.apache.org/confluence/display/NETBEANS/HiDPI+%28Retina%29+improvements

> h2. Proposed Style Guide for Vectorized Icons
> * Vector icons should be drawn in Adobe Illustrator. Each icon should be one 
> named artboard, sized to the correct size in pixels. See the attached 
> Illustrator template. (Adobe Illustrator comes with a free 7-day trial, after 
> which it's $35/month. If cost is a problem but you want to contribute your 
> time to draw icons, ask Eirik...)
> * For each icon to be vectorized, place the old bitmap version of the icon in 
> the "Old Bitmap Icons" layer in Illustrator. You can then draw the vectorized 
> version on top.
> * Since most of the existing NetBeans icons follow a quite consistent visual 
> style, and to simplify the job of creating new icons, it is best to keep the 
> shape of the new vectorized icons the same as in the old bitmap icons. For 
> instance, a rectangle of size 5x4px in the bitmap icon should probably become 
> a rectangle of 5x4px in the vector version.
> * Keep the same general colors in vectorized icons as in the corresponding 
> old bitmap icons. (The color scheme is not too hard to change later, but we 
> should do this only once most of the IDE icons have been vectorized.)
> * If the old bitmap icon is complex, it is fine to simplify it a bit when 
> drawing vectorized versions.
> * Omit gradients, bevels, and unnecessary drop shadows. They take more time 
> to draw, and with "flat design", they are now out of fashion in any case.
> * Use a stroke width of 1px around the main shapes in the icon, like in the 
> existing bitmap icons. The new icons should look consistent with the existing 
> bitmap icons, especially since we may see bitmap icons and vector icons 
> side-by-side for a long time. Within shapes, 0.5px strokes can be used for 
> finer details.
> * The 1px strokes that outline the icon's shapes should typically be 33% 
> transparent black on top of the shape's background color, or of similar 
> darkness. See the examples in the attached "style example.png" file.
> * Horizontal and vertical strokes must be aligned to the pixel grid.
> * While it may sometimes be necessary to "outline" strokes for the purposes 
> of applying boolean operations (e.g. subtracting another shape from the 
> stroke only), strokes should be left as strokes whenever possible, as this 
> leads to smaller SVG files, and makes shapes within the icon easier to modify.
> * For toolbar icons, which exist in both 16x16 and 24x24 sizes, base the 
> vector version on the smaller 16x16 one, which is sometimes simpler. (This is 
> already done in the prioritized icon list above.)
> If you wish to contribute to this effort, comment here; Eirik will coordinate 
> to make sure multiple people are not working on the same icons.
