php - problem with imagecreatefromstring function -


मैं एक स्ट्रिंग को " imagecreatefromstring "फ़ंक्शन (मैंने नीचे कोड संलग्न किया है)। यह सबसे अधिक छवियों के लिए काम करता है, लेकिन जब मैं बड़ी छवियों को बदलने की कोशिश करता हूं, तो छवि का एक छोटा सा हिस्सा परिवर्तित नहीं होता (छवि का निचला भाग सिर्फ भूरा है)

मेरा कोड है Php.net उदाहरण): 

  $ data = base64_decode ($ रिकॉर्ड ['टेक्स्ट']); $ Im = imagecreatefromstring ($ डेटा); अगर ($ im! == गलत) {हैडर ('सामग्री-प्रकार: छवि / जेपीईजी'); imagejpeg ($ im); imagedestroy ($ im); }

मैं भी स्ट्रिंग डिकोड करने के लिए एक पाइस में नहीं, बल्कि स्ट्रिंग को विभाजित करने का प्रयास करता हूं और फिर इसे डीकोड करता हूं। 

  के लिए ($ i = 0, $ len = strlen ($ रिकॉर्ड ['पाठ']); $ i & lt; $ len; $ i + = 4) {$ डेटा। = Base64_decode (substr ($ रिकॉर्ड ['पाठ'], $ i, 4)) ; }

ऐसा लगता है कि आपके डेटा को छोटा कर दिया गया है, भंडारण या पुनर्प्राप्ति पर या तो। सत्यापित करें कि आपके पास अपनी दुकान में संपूर्ण छवि है।

.net - C# List<T>.Find(x=>x.Rectangle.Contains(Point)) FAIL -

For my life, I can not understand why this code generates the following output ... I think there is a bug or something while using the list and lambda, if type one rectangle exposes the property and you use the included method of rectangle object ... and the clear statement proves true while Find list method fails .... Onway Code Public Gridskeyr Warldtokapadsb (Point location) {location = _Map.WorldToClient (location); Gridsquare gs = this.find (x => x.Rectangle.Contains (location)); GridSquare KP = G.Find (X => X. laxative canteen (location)); & Lt; GridSquare & gt; List = kp.FindAll (x => x.Rectangle.Contains (location)); U.dp (list.Count); Gridskare sub = KP.Fid (X => X. laxative canteen (location)); If (sub == faucet) {u.dp (place to look for "location"); U.dp ("The location found in the grid category" + GS toaster ()); U.dp ("Grid Square Bounds" + gs.Rectangle.ToString ()); U.dp ("location found in keypad" +...

c++ - QtQuick: QQmlApplicationEngine failed to load component qrc:/main.qml:23 Invalid attached object assignment -

Looking at my thoughts below, am I barking the wrong tree? Or in the information given below, am I misusing the Qt API to get an error in the title? I'm trying to modify the sample to work with the default coefficic project generated from Qt Creator 3.3.0 (OpenSource). Qt 5.4.0 (GCC 4.6.1, 64bit) Based on. The first thing to look at after the code is that I stand by: The sample uses the main.cpp: qmlRegisterType & lt ; Squircle & gt; ("OpenGLUARMM", 1, 0, "Squircle"); QQuickView view; View.setResizeMode (QQuickView :: SizeRootObjectToView); View.setSource (QUrl ("QRC: ///scenegraph/openglunderqml/main.qml")); View.show (); Some name changes in my name. CPP qmlRegisterType & lt; Menuscreen & gt; ("OpenGLUnderQML", 1, 0, "Main Screen"); QQmlApplicationEngine engine; Engine.load (QUrl (QStringLiteral ("QRC: /main.qml"))); I'm not sure that the difference in using QQmlApplicationEngine...
