Hi all,
I am using super dev mode and i have an issue, i think,, with same origin
policy.
I have a ClientBundle containing many ImageResource which will be used as
WebGL textures.
To load those images i do :
Image image = new Image(myImageResource.getSafeUri().asString();
RootLayoutPanel.get().add(image);
image.setVisible(false);
this.img.addLoadHandler(this);
this.img.addErrorHandler(this);
where this is a class implenting LoadHandler and ErrorHandler.
Then in the onLoad method :
this.InitializeTexture(this.img.getElement());
RootLayoutPanel.get().remove(this.img);
And finally the InitializeTexture :
/**
* \brief Initializes the gl texture with the loaded image.
*/
public void InitializeTexture(Element inElement)
{
// Set current texture object as active
this.Bind(WebGLRenderingContext.TEXTURE_2D);
// If generating mipmap is requested, parameter the texture filtering to
using them and generate mipmaps ...
if(this.generateMipmap)
{
this.gl.texParameteri(WebGLRenderingContext.TEXTURE_2D,
WebGLRenderingContext.TEXTURE_MAG_FILTER, WebGLRenderingContext.LINEAR);
this.gl.texParameteri(WebGLRenderingContext.TEXTURE_2D,
WebGLRenderingContext.TEXTURE_MIN_FILTER,
WebGLRenderingContext.LINEAR_MIPMAP_NEAREST);
this.gl.generateMipmap(WebGLRenderingContext.TEXTURE_2D);
}
else // else do not use mipmap
{
this.gl.texParameteri(WebGLRenderingContext.TEXTURE_2D,
WebGLRenderingContext.TEXTURE_MAG_FILTER, WebGLRenderingContext.LINEAR);
this.gl.texParameteri(WebGLRenderingContext.TEXTURE_2D,
WebGLRenderingContext.TEXTURE_MIN_FILTER, WebGLRenderingContext.LINEAR);
}
this.gl.texParameteri(WebGLRenderingContext.TEXTURE_2D,
WebGLRenderingContext.TEXTURE_WRAP_S, WebGLRenderingContext.CLAMP_TO_EDGE);
this.gl.texParameteri(WebGLRenderingContext.TEXTURE_2D,
WebGLRenderingContext.TEXTURE_WRAP_T, WebGLRenderingContext.CLAMP_TO_EDGE);
// And finaly, set the image pixels data in the texture object.
this.gl.texImage2D(WebGLRenderingContext.TEXTURE_2D, 0,
WebGLRenderingContext.RGBA, WebGLRenderingContext.RGBA,
WebGLRenderingContext.UNSIGNED_BYTE, inElement);
// Finaly unbind the texture object
this.Unbind(WebGLRenderingContext.TEXTURE_2D);
}
All is ok in production mode but when i use superdevmode i get under chrome
and firefox a security error while calling texImage2D method.
Do you think that is a SOP issue ?
Any idea to solve it ?
I can use superdevmode with chrome using --disable-web-security option but
i did not succeed in finding a workaround with firefox ... setting in
about:config the option security.fileuri.strict_origin_policy to false does
not help.
Regards,
Harold
