由 a 夏天 提交于 2019-11-28 01:47:09
问题 Is there any way for me to save a video in the Documents directory to the Photos Library? I have the link of the video in the documents directory, I just don't know how to save it to the Photos app. Thanks, Kevin 回答1: Use the UISaveVideoAtPathToSavedPhotosAlbum function. 回答2: If you are saving it in a local directory first, then you can save it as.. ALAssetsLibrary *assetLibrary = [[ALAssetsLibrary alloc] init]; [assetLibrary writeVideoAtPathToSavedPhotosAlbum:url completionBlock:^(NSURL

Storing a reference to an image saved in the Camera Roll

由 谁都会走 提交于 2019-11-27 23:11:51
问题 I've been working on a simple application which allows the user to take a photo and store it in the camera roll for later use. To do this, I am using a UIImagePickerController, and the method UIImageWriteToSavedPhotosAlbum, which is working perfectly. My question is: Is there any way to store the path to the image in the Camera Roll so that I can use that to call the image again later? Or, do I have to save the image in the app in order to use it again later? It would be great if there was a

How can I resize an image file uploaded with Django using an ImageField Model? [closed]

由 ⅰ亾dé卋堺 提交于 2019-11-27 20:11:21
What is the most straightforward method to resize an image file uploaded via a Django form as an ImageField ? I was annoyed that I couldn't find a complete working example, only bits here and there. I managed to put the solution together myself. Here is the complete example, I put it in clean() method of the form (you can also override models save() method, in the completely same way - changing ImageField's file property). import StringIO from PIL import Image image_field = self.cleaned_data.get('image_field') image_file = StringIO.StringIO(image_field.read()) image = Image.open(image_file) w,

PHP - Upload a web hosted photo to facebook album via Graph API

问题 I'm trying to upload www hosted (e.g. http://www.google.se/intl/en_com/images/srpr/logo1w.png) files to a facebook album.

Exif data TAG_ORIENTATION always 0

由 送分小仙女□ 提交于 2019-11-27 19:22:54
I need to know the orientation of an image from the gallery (taken by the camera). My initial approach was to use MediaStore.Images.Media.ORIENTATION which was working for my Droid 1. While testing on the HTC Thunderbolt that phone only saves 0 to that field. I then moved to reading the exif data: ExifInterface exifReader = new ExifInterface(mFilePath); exifReader.getAttributeInt(ExifInterface.TAG_ORIENTATION, -1); This also returns 0 for every image. Anyone have ideas on how to properly get the orientation of a photo take on android? dbaugh Here is the code I used onActivityResult() in my

How can I automatically determine whether an image file depicts a photo or a 'graphic'?

问题 How can I automatically determine whether an image file depicts a photo or a 'graphic'? For example using Imagemagick? 回答1: I am somewhat at the limits of my knowledge here, but I read a paper and have worked out a way to calculate image entropy with ImageMagick - some clever person might like to check it! #!/bin/bash image=$1 # Get number of pixels in image px=$(convert -format "%w*%h\n" "$image" info:|bc) # Calculate entropy # See this paper www1.idc.ac.il/toky/imageProc-10/Lectures/04

Access Photo Album from iPhone Code

由 巧了我就是萌 提交于 2019-11-27 18:23:39
问题 iPhone Apps like "Picture Map" access all the photos in my iPhone's camera album and display them without ever showing an Image Picker Control. Does anyone know how this is done? Thanks G 回答1: This is an old thread but I will answer as I'm the one who wrote and published Picture Map ! Thomas is right, I was accessing the DCIM folder to parse each file (to get its location from the EXIF structure and to access thumbnails too). As an application has no right to access files outside of its
