[ft-devel] How to use Standalone?

[Aya Koshigaya]

Hi,

I am trying to use the Standalone rasterizer, but have some problems with it..

This is how I am rendering the glyph-outline:

FT_Bitmap bmp;
bmp.buffer = (unsigned char*)bitmap->getBuffer();
bmp.width = bitmap->getWidth();
bmp.rows = bitmap->getHeight();
bmp.pitch = bitmap->getWidth();
bmp.num_grays = 256;
bmp.pixel_mode = FT_PIXEL_MODE_GRAY;

FT_Raster_Params params;
CIMath::zeroMemory(&params, sizeof(params));
params.source = &outl;
params.target = &bmp;
params.flags = FT_RASTER_FLAG_AA;

ft_standard_raster.raster_render((FT_Raster)raster, &params);


the bitmap has a size of 512x512 and is only one grayscale channel.
The resulting image looks like this:

But why..? it's not a fault of my bitmap or the display - I think I forgot someting in the Standalone Rasterizer..

Anyway, is there somewhere a nice example of how to use the Standalone Rasterizer?
