示例1: _create_proxy_rawpy
# 需要导入模块: from wand.image import Image [as 别名]
# 或者: from wand.image.Image import fromarray [as 别名]
def _create_proxy_rawpy(self, source, dest, mode):
# maybe Pillow supports this file type directly?
if not self.image:
try:
self.image = Image.open(source)
except IOError:
pass
except Exception as e:
logging.error('cannot read {}: {}'.format(source, e.args[0]))
raise e
# obviously not, try decoding as Raw
if not self.image:
try:
raw = rawpy.imread(source)
rgb = raw.postprocess(use_camera_wb=True, no_auto_bright=True)
self.image = Image.fromarray(rgb)
except Exception as e:
logging.error('cannot read {}: {}'.format(source, e.args[0]))
raise e
image = self.image.copy()
if mode == self.PROXY_FULLSIZE:
pass
elif mode == self.PROXY_THUMBNAIL:
image.thumbnail(settings.THUMBNAILSIZE)
elif mode == self.PROXY_WEBSIZED:
image.thumbnail(settings.WEBSIZE)
try:
image.save(dest)
except Exception as e:
logging.error('cannot write {}: {}'.format(dest, e.args[0]))示例2: normalize_image
# 需要导入模块: from wand.image import Image [as 别名]
# 或者: from wand.image.Image import fromarray [as 别名]
def normalize_image(img):
img_rgba = img.convert('RGBA')
arr = numpy.array(numpy.asarray(img_rgba).astype('float'))
return Image.fromarray(normalize(arr).astype('uint8'),'RGBA')
