UPDATE: I shortened the function for readibility but I am still displaying nothing but blank on my qt window. My IDE prompts me that I am missing a QImage on this line QtGui.QPixmap.fromImage(img)which is odd sicne I am passing something into it and calling it straight from QtGui Module. I can't help but think I am missing something?
def returnPixMap(self, ddsPath): glWidget = QGLWidget() glWidget.makeCurrent() texture = glWidget.bindTexture(ddsPath) width = -1 height = -1 glBindTexture(GL_TEXTURE_2D, texture) width = glGetTexLevelParameteriv(GL_TEXTURE_2D, 0, GL_TEXTURE_WIDTH) height = glGetTexLevelParameteriv(GL_TEXTURE_2D, 0, GL_TEXTURE_HEIGHT) pbuffer = QGLPixelBuffer(QtCore.QSize(width, height), glWidget.format()) pbuffer.drawTexture(QtCore.QRectF(-1, -1, 2, 2), texture) img = pbuffer.toImage() return QtGui.QPixmap.fromImage(img) On Monday, 17 August 2015 15:26:49 UTC+2, Benjam901 wrote: > > Hello all, > > I am having some trouble loading a dds file into PyQt for displaying in a > window. > > I have dug around and I keep being pointed towards OpenGL.GL and QtOpenGL. > I found a function on tech artists forum > http://tech-artists.org/forum/showthread.php?5196-Simple-DDS-loader that > supposedly returns a Qimage from a dds filepath but when the function tries > to bind the texture it fails instantly or returns 0.
