> 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.
