Fails on Firefox, works on Chromium

[raould]

Ubuntu 14.04 lts x86, FF 39.0, just upgraded to lime 2.5.2, openfl 3.2.0, haxe 3.2.0. Trying to make something using HaxePunk. Same problem that I saw in lime 2.4.9 where things work ok in Chromium, but the non-tilemap sprites do not appear in Firefox.

IndexSizeError: Index or size is negative or greater than the allowed amount

on this line of code:

    if(sourceImage.buffer.get_src() != null) image.buffer.__srcContext.drawImage(sourceImage.buffer.get_src(),sourceRect.x + sourceImage.offsetX | 0,sourceRect.y + sourceImage.offsetY | 0,sourceRect.width | 0,sourceRect.height | 0,destPoint.x + image.offsetX | 0,destPoint.y + image.offsetY | 0,sourceRect.width | 0,sourceRect.height | 0);

in this method:

lime_graphics_utils_ImageCanvasUtil.copyPixels = function(image,sourceImage,sourceRect,destPoint,alphaImage,alphaPoint,mergeAlpha) {
    if(mergeAlpha == null) mergeAlpha = false;
    if(destPoint.x >= image.width || destPoint.y >= image.height) return;
    if(alphaImage != null && alphaImage.get_transparent()) {
        if(alphaPoint == null) alphaPoint = new lime_math_Vector2();
        var tempData = image.clone();
        tempData.copyChannel(alphaImage,new lime_math_Rectangle(alphaPoint.x,alphaPoint.y,sourceRect.width,sourceRect.height),new lime_math_Vector2(sourceRect.x,sourceRect.y),lime_graphics_ImageChannel.ALPHA,lime_graphics_ImageChannel.ALPHA);
        sourceImage = tempData;
    }
    lime_graphics_utils_ImageCanvasUtil.sync(image);
    if(!mergeAlpha) {
        if(image.get_transparent() && sourceImage.get_transparent()) image.buffer.__srcContext.clearRect(destPoint.x + image.offsetX,destPoint.y + image.offsetY,sourceRect.width + image.offsetX,sourceRect.height + image.offsetY);
    }
    lime_graphics_utils_ImageCanvasUtil.sync(sourceImage);
    if(sourceImage.buffer.get_src() != null) image.buffer.__srcContext.drawImage(sourceImage.buffer.get_src(),sourceRect.x + sourceImage.offsetX | 0,sourceRect.y + sourceImage.offsetY | 0,sourceRect.width | 0,sourceRect.height | 0,destPoint.x + image.offsetX | 0,destPoint.y + image.offsetY | 0,sourceRect.width | 0,sourceRect.height | 0);
};

I'm also getting this error with dev HaxeFlixel, Firefox 39.0 on Windows 8.1 and 10, for those same haxelib versions. Latest Chrome and Opera are fine though.

@raould I added a check in ImageCanvasUtil copyPixels to make sure it didn't draw anything with width or height of 0 and that gets things rendering for me:

if (sourceImage.buffer.src != null) {

    // New check
    var width:Int = Math.floor(sourceRect.width);
    var height:Int = Math.floor(sourceRect.height);     
    if(width == 0 || height == 0) {
        return;
    }

    image.buffer.__srcContext.drawImage (sourceImage.buffer.src, Std.int (sourceRect.x + sourceImage.offsetX), Std.int (sourceRect.y + sourceImage.offsetY), Std.int (sourceRect.width), Std.int (sourceRect.height), Std.int (destPoint.x + image.offsetX), Std.int (destPoint.y + image.offsetY), Std.int (sourceRect.width), Std.int (sourceRect.height));

}

This is assuming it is this problem: http://stackoverflow.com/a/21608118/1333253
