The image is scaled from it's full size 3kx2k as taken directly from the iPhone, it is drawn into a 256x256 canvas using a destination scale. What it draws is incorrect. Works on desktop Safari, Chrome and Android Chrome I'm going to guess it's a size issue since trying smaller images works. See http://greggman.com/downloads/examples/webkit-photo-issue/webkit-photo-issue-3.html The problem is I'm using the <input type="file" accept="image/*"> to allow a web page to use an image the user takes or selects. The fact that I can't then actually use that image in a webpage with the canvas API seems like some limits need to be bumped up? 1013836 1 232625 dbates 2014-06-06 12:14:07 -0700 Created attachment 232625 [Web Archive] greggman.com/downloads/examples/webkit-photo-issue/webkit-photo-issue.html For historical preservation attached a web archive of <http://greggman.com/downloads/examples/webkit-photo-issue/webkit-photo-issue.html> as it appeared on 06/06/2014.

As far as I can tell this has been a problem since iOS6. I have also reported this in the Apple Bug Reporter - case 17917149. We would really appreciate this being fixed. 1032692 3 simon.fraser 2014-09-02 10:45:57 -0700 Did you try in an iOS 8 seed? 1032708 4 keving 2014-09-02 11:21:05 -0700 I was asked to try this in iOS8 beta 5 but my sample code would not run at all. As far as I could tell it was a problem with FileReader. I updated my original report with this information on the 12th August and also logged a new case on the 14th August relating to the new problem I found (18016794). 1032709 5 keving 2014-09-02 11:21:45 -0700 Note: 18016794 is for Apple Bug Reporter and not WebKit. 232625 2014-06-06 12:14:07 -0700 2014-06-06 12:14:07 -0700 [Web Archive] greggman.com/downloads/examples/webkit-photo-issue/webkit-photo-issue.html greggmann-webkit-photo-issue_060614.webarchive application/x-webarchive 1779 dbates YnBsaXN0MDDRAQJfEA9XZWJNYWluUmVzb3VyY2XVAwQFBgcICQoLDF8QD1dlYlJlc291cmNlRGF0 YV8QE1dlYlJlc291cmNlTUlNRVR5cGVfEBtXZWJSZXNvdXJjZVRleHRFbmNvZGluZ05hbWVfEBRX ZWJSZXNvdXJjZUZyYW1lTmFtZV5XZWJSZXNvdXJjZVVSTE8RBbw8IURPQ1RZUEUgaHRtbD48aHRt bD48aGVhZD48L2hlYWQ+PGJvZHk+CjxzdHlsZT4KY2FudmFzIHsKICAgIGJvcmRlcjogMXB4IHNv bGlkIGJsYWNrOwp9Cgo8L3N0eWxlPgo8Y2FudmFzIGlkPSJjIiB3aWR0aD0iMjU2IiBoZWlnaHQ9 IjI1NiI+PC9jYW52YXM+CjxzY3JpcHQ+CnZhciBpbWFnZSA9IG5ldyBJbWFnZSgpOwppbWFnZS5h ZGRFdmVudExpc3RlbmVyKCdsb2FkJywgZHJhd0ludG9DYW52YXMsIGZhbHNlKTsKaW1hZ2Uuc3Jj ID0gInBob3RvLmpwZyI7CgpmdW5jdGlvbiBkcmF3SW50b0NhbnZhcygpIHsKICB2YXIgY2FudmFz ID0gZG9jdW1lbnQuZ2V0RWxlbWVudEJ5SWQoImMiKTsKICB2YXIgY3R4ID0gY2FudmFzLmdldENv bnRleHQoIjJkIik7CgogIC8vIGZpZ3VyZSBvdXQgaG93IHRvIHNjYWxlIHRoZSBpbWFnZSB0byBm aXQgdGhlIGNhbnZhcwogIHZhciBkc3RXaWR0aDsKICB2YXIgZHN0SGVpZ2h0OwogIHZhciBkc3RY OwogIHZhciBkc3RZOwogIGlmIChpbWFnZS53aWR0aCA8IGltYWdlLmhlaWdodCkgewogICAgZHN0 V2lkdGggID0gY2FudmFzLndpZHRoOwogICAgZHN0SGVpZ2h0ID0gTWF0aC5mbG9vcihpbWFnZS5o ZWlnaHQgKiBkc3RXaWR0aCAvIGltYWdlLndpZHRoKTsKICAgIGRzdFggPSAwOwogICAgZHN0WSA9 IE1hdGguZmxvb3IoKGNhbnZhcy5oZWlnaHQgLSBkc3RIZWlnaHQpIC8gMik7CiAgfSBlbHNlIHsK ICAgIGRzdEhlaWdodCA9IGNhbnZhcy5oZWlnaHQ7CiAgICBkc3RXaWR0aCAgPSBNYXRoLmZsb29y KGltYWdlLndpZHRoICogZHN0SGVpZ2h0IC8gaW1hZ2UuaGVpZ2h0KTsKICAgIGRzdFggPSBNYXRo LmZsb29yKChjYW52YXMud2lkdGggLSBkc3RXaWR0aCkgLyAyKTsKICAgIGRzdFkgPSAwOwogIH0K CiAgLy8gRHJhdyB0aGUgaW1hZ2UgaW50byB0aGUgY2FudmFzIGF0IHRoZSByaWdodCBzY2FsZQog IGN0eC5kcmF3SW1hZ2UoaW1hZ2UsIGRzdFgsIGRzdFksIGRzdFdpZHRoLCBkc3RIZWlnaHQpOwp9 Cgo8L3NjcmlwdD4KCgo8ZGl2IGNsYXNzPSJpYWR0b29sLWNsb3NlLWJ1dHRvbiBpYWR0b29sLWZh dXgtY2xvc2UtYnV0dG9uIGlvLWhpZGRlbiI+PC9kaXY+PGRpdiBpZD0iaW8taW1hZ2UtaW1wb3J0 LWRpYWxvZyIgY2xhc3M9ImlvLWRpYWxvZyBpby1tb2RhbCBpby1oaWRkZW4iPjxwPkFkZCBpbWFn ZXMgdG8geW91ciBsaWJyYXJ5LjwvcD48aW5wdXQgdHlwZT0iZmlsZSIgbXVsdGlwbGU9IiI+PGRp diBpZD0iaW8taW1hZ2UtaW1wb3J0LWJ1dHRvbi1jb250YWluZXIiIGNsYXNzPSJpby1jZW50ZXIt aG9yaXpvbnRhbCI+PGJ1dHRvbj5DbG9zZTwvYnV0dG9uPjwvZGl2PjwvZGl2PjxkaXYgY2xhc3M9 ImlvLWhpZGRlbiIgc3R5bGU9InBvc2l0aW9uOiBhYnNvbHV0ZTsgdG9wOiAwcHg7IGxlZnQ6IDBw eDsgb3BhY2l0eTogMC43NTsgcG9pbnRlci1ldmVudHM6IG5vbmU7IHotaW5kZXg6IDEwMDA7Ij48 aW1nPjwvZGl2PjwvYm9keT48L2h0bWw+WXRleHQvaHRtbFVVVEYtOFBfEFFodHRwOi8vZ3JlZ2dt YW4uY29tL2Rvd25sb2Fkcy9leGFtcGxlcy93ZWJraXQtcGhvdG8taXNzdWUvd2Via2l0LXBob3Rv LWlzc3VlLmh0bWwACAALAB0AKAA6AFAAbgCFAJQGVAZeBmQGZQAAAAAAAAIBAAAAAAAAAA0AAAAA AAAAAAAAAAAAAAa5
