I tried to clarify what the lib does currently, but applogise if was spammy

wow, thats alot of text 😅

i guess the main thing to me is how is relevant to haxeui - what do these things draw to... js canvas? Because why would i use this over svg (which haxeui-html5 canvas supports), i mean, haxeui-kha doesnt have a canvas impl, are you saying this could be used for that? How would it draw "kha" pixels?

well pixelimage has no GPU acceleration so it is probably better to mix with cornerContour and look to add TriGML to that if you really need speed. But it should be viable currently with some changes.. will have to modify 'view8' method ( used js.html.UInt8 for simplicity and easy view ) and a few other details for c++, but essentially.

Haxe
var p = new PixelShape(1024, 1024 );
p.transparent = true;
var arcPie = 
    '<ArcShape 
        left="100"  top="100" 
        width="500" height="480" 
        strokeColor="0xFFFF0000" strokeWidth="12" 
        fill="0xFF00FF00" 
        startAngle="0" sweepAngle="240"
        arcType="pie">
    </ArcShape>';
 TriangleGML.withString( p, arcPie, 10, 10 );
Image.fromBytes( p.byteImage().getBytes(), p.width, p.height, TextureFormat.RGBA32 );
var g2 = framebuffer.g2;
g2.begin();
g2.clear(Color.fromValue(0xff000000));
g2.drawImage( image, 0, 0 );
g2.end();

I don't know much about g1 it is for lower end hardware I think, you would just loop though the pixelimage, maybe the internal RGBA format currently would be ok so direct access rather than getARGB, may need private access to image allowed.

Haxe
var g1 = frameBuffer.g1;
g1.begin();
// g1 clear??
var p = new PixelShape(1024, 1024 );
p.transparent = true;
var arcPie = 
    '<ArcShape 
        left="100"  top="100" 
        width="500" height="480" 
        strokeColor="0xFFFF0000" strokeWidth="12" 
        fill="0xFF00FF00" 
        startAngle="0" sweepAngle="240"
        arcType="pie">
    </ArcShape>';
TriangleGML.withString( p, arcPie, 10, 10 );
var x = 0;
var y = 0;
var xx = 0;
var maxX = x + p.width;
var maxY = y + p.height;
while( true ){
   g1.setPixel(x, y, p.image[ position( x++, y ) ] );
   if( x > maxX ){
     x = xx;
     y++;
   } 
   if( y > maxY ) break;
}
g1.end();

for flixel, nme, lime have some potential hook ups. but I was more thinking for wxwidgets or something??

by the way fixed the arc sample see projects for link

I am really not sure if performance is going to be fast enough for some things... recent undo changes to the project have increased the compile a lot 😦

I may try adding flixel and peote before kha??

for g1 what might be interesting even if the output hardware target does not support alpha pixels.. you can still compose the image with alpha blends of shapes and just loop through and setPixel solid ones. there is Vision support but worry it maybe too heavy and should maybe add simple kernel matrix filters myself

for graphics4 then triangles with cornerContour will be much faster

i mean, wx and kha sound interesting though i still think it would need to be like an external canvas replacement (shadowing or something) since adding dependency for something like that isnt something id do. Especially when all these backends have their own drawing primitives (including wx). Im not saying that it couldnt be an interesting enhancement (as a third party library / addon) though

do you know what capablities wx has... can it do gradients

can it do soft edges

can it skew and rotate images reasonably?

does it have much hittest

does it blend alpha

well, it has "device contexts" which are basically drawing surfaces, and it also has a glView (though i feel like that is out of scope)

ah

glView is like openGL

?

yeah, i think so, never investigate that before... played with wxDC's before though

Cairo does not really have gradient triangles yet

apparently there is

wxDC::GradientFillLinear()

pixelimage constructs from gradient triangles and quads mostly so it is relatively easy to do some complex gradient stuff

yet to setup edge smoothing for that and need to check not broken anythinh

I think grahically something like a charts component maybe ideal..

and this outputs pixels? I mean, how would that work with wx?

yes
