Hi,
my WebGL export from my project has a error i can not resolv:
WEBGL11130: INVALID_OPERATION: texSubImage2D: Daten müssen in einem typisierten Array übergeben werden
Datei: emwi_0_98.js, Zeile: 5088, Spalte: 5
The code witch makes problems:
// ---------------------------------------------------------------------------
// The function GetGlyph() determines the glyph of the given font and ensures
// that the glyph is available in the glyph cache surface. If successful, the
// function returns an object containing the glyph metrics and the position
// within the glyph cache surface where the glyph is available. If the glyph
// is not available in the cache, the function reserves space in the cache and
// loads there the glyph pixel data. In the case, the entire cache is occupied
// and all glyphs are in use, the function fail and returns null. In such case
// the preceding text operation need to be terminated before new glyphs can be
// loaded.
// ---------------------------------------------------------------------------
emwi._GetGlyph = function( aFont, aCharCode )
{
// No valid font specified
if ( !aFont )

console.log( "EmWi error: Invalid font resource." );
return null;
}
var glyph = aFont.Cache[ aCharCode ];

// the glyph to the beginning of the glyph list.

// Prepare a temp. buffer to receive the decomporessed glyph pixel
var size = glyph.Width * glyph.Height;
var pixel = new Uint8Array( size );
var gl = this._Context;
// Decompress the pixel data into the previously created buffer
aFont.DecompressProc( aFont.Pixel, pixel, glyph.Pixel, glyph.NoOfBits );
XOrRows( pixel, size, glyph.Width );
// Transfer the pixel information into the glyph cache surface
gl.bindTexture( gl.TEXTURE_2D, this._GlyphCacheTexture );
gl.texSubImage2D( gl.TEXTURE_2D, 0, glyph.CacheX, glyph.CacheY, glyph.Width,
glyph.Height, gl.ALPHA, gl.UNSIGNED_BYTE, pixel );
I am using EmWi 8.20.
Thanks.
