- Moving dot patch gives 17 ms interframe times but only on old Kuna laptop, not on newer white MacBook
- setText apparently takes a lot of time, dozens of msec (debugText.setText)
Changes made to visual.py and misc.py
In misc.py:
- the following code has been inserted above the line that imports image and cPickle:
def ObjectArray(inputSeq):
return numpy.array(inputSeq, 'O')
- and the function attribute "numpy.array"has been added to the line defining the variable cmSize in the definition of the function 'deg2pix' to yield:
cmSize = deg2cm(numpy.array(degrees), monitor)
In visual.py:
- The following code has been added above the 'def setVertices' line to allow us to set the contrast, and colour of the fill and lines within shapestim:
def setFillRGB(self,value,operation=None): #expects three values
if type(value) in [tuple,list]:
value=numpy.asarray(value,float)
self.fillRGB=numpy.array(value, float)
#print 'fillRGB type=',type(self.fillRGB),' =',self.fillRGB,'whereas value wanted to assign=',value,
#print ' and self =',self
def setLineRGB(self,value,operation=None): #expects three values
if type(value) in [tuple,list]:
value=numpy.asarray(value,float)
self.lineRGB=numpy.array(value, float)
#print 'lineRGB type=',type(self.lineRGB),' =',self.lineRGB,'whereas value wanted to assign=',value,
#print ' and self =',self
#if we don't have shaders we need to rebuild the texture
#if not self._useShaders:
# self.setTex(self._texName)
def setFillContrast(self,value): #THIS DOESN'T WORK
self.contrast = value
desiredRGB = (self.fillRGB*self.contrast+1)/2.0#RGB in range 0:1 and scaled for contrast
#print 'desiredRGB type=',type(desiredRGB),' =',desiredRGB
if numpy.any(desiredRGB**2.0>1.0): #if outside -1,1 range, then
desiredRGB=numpy.array([0.6,0.6,0.4]) #set to arbitrary val
self.setFillRGB(value=desiredRGB) #self is understood
