    i dont want to start creating a bunch of abstracts (like canvas) when they arent in wx
  • o
    the advantage around image is that you have the width, height and so you could setRgb( x, y, color )
  • b
    thats not the point of hxwidgets
  • o
    ok well RawPointer for getData and getAlpha would be useful ...
  • b
    yeah, i guess you would need cx / cy if you wanted to build a nicer interface...
  • b
    ill have a think / play
  • o
    The one thing I am not sure around if your image has alpha or not... do you need to step in for loop access different amounts.
  • o
    so for( i in 0...l*2 )
  • b
    from the docs it looks like the alpha channel is stored totally separately
  • o
    so is each drawData call cost anything?
  • b
    drawData?
  • o
    so is there any cost in setting pixels individually rather than setting a whole array
  • o
    getData
  • o
    sorry
  • s
    can 
    Dialogs.messageBox
    be called anywhere?
  • o
    I guess thats done in layoun.
  • b
    i wouldnt expect any significant cost if you are accessing the raw data... i would guess its as fast as just changing values in memory
  • o
    layount
  • o
    layout
  • b
    yup
  • b
    well, i think after you have modified the image, you would have to let the wx control that is displaying it to update
  • s
    my xml deserializer is not in a component class
  • s
    so 👍
  • b
    cool - yeah, it doesnt need to be
  • s
    idk why i thought that; it's a static class
  • b
    Copy code
    haxe
        image.imageData.setRGB(10, 0, 255, 0, 0);
        image.imageData.setRGB(10, 1, 0, 255, 0);
        image.imageData.setRGB(10, 2, 0, 0, 255);
