Pixel array to 2d array representation

[Bk8]

I'm trying to integrate the lunasvg to a juce project, but I'm getting a weird behavior while trying to set the pixels to the 2d array representation in Juce. The color seems ok but not the order of the pixels, could someone help me please? The image renders corrrectly with the png demo.

`

auto document = Document::loadFromFile("focus.svg");
auto bitmap = document->renderToBitmap();
int height = document->height();
int width = document->width();

juce::Image img(juce::Image::PixelFormat::ARGB, width, height, true);

std::uint8_t* data = bitmap.data();

//RGBA to  ARGB 

for (int i = 0; i < width * height; i++)
{
    int x = i % width;
    int y = i / width;
    img.setPixelAt(x, y, juce::Colour(data[(4 * i) + 2], data[(4 * i) + 1], data[(4 * i) + 0], data[(4 * i) + 3]));
}

g.drawImageAt(img, 0, 0);`

lunasvg default pixel format is ARGB Premultiplied alpha

Thank you!

Also the width and height of the document was different to the bitmap.

I changed this: int height = document->height(); int width = document->width(); to this: int height = bitmap.height(); int width =bitmap.width();

It worked but it's this ok? why are this values different in the document and the bitmap?

why are this values different in the document and the bitmap?

Document::width Returns the width of the document as specified in the file Document::height Returns the height of the document as specified in the file

Bitmap::width Returns the width of the rendered document Bitmap::height Returns the height of the rendered document

Document::renderToBitmap can return a 'Bitmap' size that is different from the 'Document' size

So use this to be safe while handling Bitmap

int height = bitmap.height();
int width = bitmap.width()
