示例1: testRemoteImage
# 需要导入模块: from qgis.core import QgsApplication [as 别名]
# 或者: from qgis.core.QgsApplication import imageCache [as 别名]
def testRemoteImage(self):
"""Test fetching remote image."""
url = 'http://localhost:{}/qgis_local_server/sample_image.png'.format(str(TestQgsImageCache.port))
image, in_cache = QgsApplication.imageCache().pathAsImage(url, QSize(100, 100), 1.0, True)
# first should be waiting image
self.assertTrue(self.imageCheck('Remote Image', 'waiting_image', image))
self.assertFalse(QgsApplication.imageCache().originalSize(url).isValid())
self.waitForFetch()
# second should be correct image
image, in_cache = QgsApplication.imageCache().pathAsImage(url, QSize(100, 100), 1.0, True)
self.assertTrue(self.imageCheck('Remote Image', 'remote_image', image))
self.assertEqual(QgsApplication.imageCache().originalSize(url), QSize(511, 800), 1.0)示例2: testRemoteImageMissing
# 需要导入模块: from qgis.core import QgsApplication [as 别名]
# 或者: from qgis.core.QgsApplication import imageCache [as 别名]
def testRemoteImageMissing(self):
"""Test fetching remote image with bad url"""
url = 'http://localhost:{}/qgis_local_server/xxx.png'.format(str(TestQgsImageCache.port)) # oooo naughty
image, in_cache = QgsApplication.imageCache().pathAsImage(url, QSize(100, 100), 1.0, True)
self.assertTrue(self.imageCheck('Remote image missing', 'waiting_image', image))示例3: setUp
# 需要导入模块: from qgis.core import QgsApplication [as 别名]
# 或者: from qgis.core.QgsApplication import imageCache [as 别名]
def setUp(self):
self.report = "<h1>Python QgsImageCache Tests</h1>\n"
