* Graph Perf Counter: Use GlueGen's Clock.currentNanos() to ease on ↵Sven Gothel2023-03-071-13/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | performance-hit measuring performance. This was mostly notable on a Raspberry-Pi 4 arm64, where perfromance degragated around 3x using high-freq counter. Using our well determined Clock.currentNanos() removes this overhead, back to 'easy measuring' and having a well defined 'currentNanos()' since module start. TestTextRendererNEWT00 can enable Region and Font perf-counter w/ '-perf', w/o it only uses its own counter and hence reduce the high-freq burden (64% perf win on raspi4). +++ Below numbers show that Region.addOutlineShape() perhaps needs a little performance work to allow long text to be processed in 'real time' on embedded platform. Hower, usually we cache the Region for long text and can have at least one liner to be renderer within 60fps fast, i.e. Region produced in ~26ms for a 81 char line instead of ~130ms for 664 chars. +++ Raspberry Pi 4b, OpenJDK17, Debian 11: Using current medium sized text_1 w/ 664 chars, w/o '-perf' and after having passed 40 frames, we have following durations: - process the OutlineShape -> Region: 129ms (text) - Render the Region: 53ms Startup Times: - loading GlueGen - loading test 0 [ms] - loading GlueGen - start test 1,910 [ms] - loading test - start test 1,910 [ms] - loading test - gl 2,631 [ms] - loading test - graph 2,636 [ms] - loading test - txt 2,844 [ms] - loading test - draw 3,062 [ms] Perf .. 1 / 1: Perf Launch: Total: graph 5, txt 207, draw 218, txt+draw 425 [ms] 1 / 1: Perf Launch: PerLoop: graph 5,505,740, txt 207,530,736, draw 218,393,680, txt+draw 425,924,416 [ns] 20 / 20: Perf Frame20: Total: graph 16, txt 376, draw 281, txt+draw 657 [ms] 20 / 20: Perf Frame20: PerLoop: graph 807,055, txt 18,820,824, draw 14,075,146, txt+draw 32,895,970 [ns] 20 / 40: Perf Frame40: Total: graph 3, txt 129, draw 53, txt+draw 182 [ms] 20 / 40: Perf Frame40: PerLoop: graph 176,670, txt 6,451,330, draw 2,658,217, txt+draw 9,109,547 [ns] +++ On a modern desktop (~2y old), GNU/Linux Debian 11, AMD GPU on Mesa3D: Using current medium sized text_1 w/ 664 chars, w/o '-perf' and after having passed 40 frames, we have following durations: - process the OutlineShape -> Region: 42ms (text) - Render the Region: 5ms Startup Times: - loading GlueGen - loading test 0 [ms] - loading GlueGen - start test 310 [ms] - loading test - start test 309 [ms] - loading test - gl 459 [ms] - loading test - graph 460 [ms] - loading test - txt 490 [ms] - loading test - draw 506 [ms] Perf .. 1 / 1: Perf Launch: Total: graph 1, txt 29, draw 15, txt+draw 45 [ms] 1 / 1: Perf Launch: PerLoop: graph 1,191,096, txt 29,868,436, draw 15,519,445, txt+draw 45,387,881 [ns] 20 / 20: Perf Frame20: Total: graph 240, txt 68, draw 21, txt+draw 89 [ms] 20 / 20: Perf Frame20: PerLoop: graph 12,045,651, txt 3,415,402, draw 1,069,348, txt+draw 4,484,750 [ns] 20 / 40: Perf Frame40: Total: graph 283, txt 42, draw 5, txt+draw 47 [ms] 20 / 40: Perf Frame40: PerLoop: graph 14,152,395, txt 2,116,114, draw 265,292, txt+draw 2,381,406 [ns]

| | | | | | | | | | | | | | mapping, rely on no-shape for 'space' non-contour. Drop erroneous Glyph ID_SPACE, ID_CR to rely on no-shape for 'space' non-contour resolves different cmap-mappings of fonts, not following 'some std'. Hence getGlyph(glyph_id) no more uses the `font.getGlyph(Glyph.ID_UNKNOWN)` shape, but a null-shape as intended and using the hmtx and hhea table values for asvance and bounds. This fixes 'space' spacing in general and specifically FreeSerif-Regular and the like. This path also simplifies processing/layout of glyphs in process(..) and get*BoundsFU(..).

* Font/Graph, {Font, Glyph}/Typecast: Add kerning and expose values in ↵Sven Gothel2023-02-103-136/+466

This finally provides proper device and resolution independent font utilization. Further, preliminary kerning has been added. +++ Also ... TypecastFont: - getGlyphID(..) getGlyph(..) enforce symbol mapping to Glyph.ID_SPACE Glyph.ID_CR, as some fonts ave an erroneous cmap (FreeSerif-Regular) - add getKerning(..) TODO: Add binary search - Set TypecastFont.USE_PRESCALED_ADVANCE := false, i.e. dropping all prescaled pixel-sized advance values mapped to font pixel-size as we utilize font-units only for later uniform scaling. - Drop virtual getPixelSize() and add static FontScale.toPixels(..) - Add fullString() for debugging purposed, including some font tables
