QGLWidget and JPEG
I need to view JPEG from IP-camera. My code:
resizeGL(int width, int height)
@texture = bindTexture(QImage::fromData(jpg));@
I successfully get JPEG from camera, but I see only grey rectangle.
Ok, I try check this function with local image, but I get strange result:
@texture = bindTexture(QImage("/tmp/test.jpg"));@
I view brown rectangle.
@texture = bindTexture(QString("/tmp/test.jpg"));@
I view white rectangle.
My question - how can I see JPEG with QGLWidget and OpenGL.
Thank you and excuse me for my bad english.
bq. QImage QGLWidget::convertToGLFormat ( const QImage & img ) [static]
Converts the image img into the unnamed format expected by OpenGL functions such as glTexImage2D(). The returned image is not usable as a QImage, but QImage::width(), QImage::height() and QImage::bits() may be used with OpenGL. The GL format used is GL_RGBA.
Why if I don't use glTexImage2D and etc or bindTexture don't convert image?
Are you calling
in your code?
I post all code. I think what I don't need mixture OpenGL and Qt functions.
