示例1: loadImage
# 需要导入模块: from panda3d.core import PNMImage [as 别名]
# 或者: from panda3d.core.PNMImage import getReadYSize [as 别名]
def loadImage(self,file_path,cols,rows,scale_x,scale_y,frame_rate):
# Make a filepath
image_file = Filename(file_path)
if image_file .empty():
raise IOError, "File not found"
return False
# Instead of loading it outright, check with the PNMImageHeader if we can open
# the file.
img_head = PNMImageHeader()
if not img_head.readHeader(image_file ):
raise IOError, "PNMImageHeader could not read file %s. Try using absolute filepaths"%(file_path)
return False
# Load the image with a PNMImage
full_image = PNMImage(img_head.getXSize(),img_head.getYSize())
full_image.alphaFill(0)
full_image.read(image_file)
right_image = PNMImage(img_head.getXSize(),img_head.getYSize())
left_image = PNMImage(img_head.getXSize(),img_head.getYSize())
right_image.copyFrom(full_image)
left_image.copyFrom(full_image)
left_image.flip(True,False,False)
# storing individual sprite size
self.size_ = (right_image.getReadXSize()/cols,right_image.getReadYSize()/rows)

return True示例2: getTotalClickableArea
# 需要导入模块: from panda3d.core import PNMImage [as 别名]
# 或者: from panda3d.core.PNMImage import getReadYSize [as 别名]
def getTotalClickableArea(self):
'''Compute the total clickable area, and compute its percentage relative to the image total size'''
### RENDERING CLICKABLE AREA
# Prepare the rendering of the clickable area
self.renderClickableArea()
# Render the frame
self.base.graphicsEngine.renderFrame()
### FETCHING THE RENDERED IMAGE
# Prepare the variable that will store the frame image (in a PNMImage class, this is NOT a file format, but a convenient image manipulation class offered by Panda3D)
screenshot = PNMImage()
# Set display region to the default
dr = base.camNode.getDisplayRegion(0)
# Store the rendered frame into the variable screenshot
dr.getScreenshot(screenshot)
### COMPUTE THE CLICKABLE AREA PERCENTAGE
# Prepare an histogram object
hist = PNMImage().Histogram()
# Compute the histogram
screenshot.makeHistogram(hist)
# Get the number of white opaque pixels (the clickable area)
totalClickableArea = hist.getCount(PNMImageHeader.PixelSpec(255,255,255, 255))
# Get the percentage of clickable area relative to the total image size
totalClickableAreaPercentage = float(totalClickableArea) * 100 / (screenshot.getReadXSize() * screenshot.getReadYSize())
if self.debug:
print("Total unique intensity pixels: %f" % hist.getNumPixels())
print("Total clickable area: %f" % totalClickableArea)
totalClickableAreaSqrt = sqrt(float(totalClickableArea))
print("Total clickable area sqrt: %f" % totalClickableAreaSqrt)

print("Total clickable area percentage: %f" % totalClickableAreaPercentage)
blackarea = hist.getCount(PNMImageHeader.PixelSpec(0,0,0, 255))
print("Total black area: %f" % blackarea)
print("Total black area percentage: %f" % (float(blackarea) * 100 / (screenshot.getReadXSize() * screenshot.getReadYSize())) )
return totalClickableAreaPercentage
