Telling IKImageBrowserView not to schedule preloading

由 懵懂的女人 提交于 2020-01-01 06:51:26
问题 For our rewrite of the open-source iMedia framework project (in use currently by dozens of developers), we are switching to IKImageBrowserView, and having a troubling time with caching. It appears that IKImageBrowserView likes to preload/prefetch a cache of images, as a low-priority background task, as many not-yet-visible items that it can. This might be useful, except that we don't want to load the CPU (and network for remotely-retrieved images) if we can help it. Especially since we have

由 筅森魡賤 提交于 2019-12-13 16:03:41
问题 I'm working on an OSX app that should be able to scan a view images, then generate a PDF and so on. But I'm already stuck in the first step, since it seems I can't get IKScannerDeviceView to work and there is little to no help to be found. This is what I have until now, following another question here: import Cocoa import Quartz class ViewController: NSViewController, IKScannerDeviceViewDelegate, ICScannerDeviceDelegate, ICDeviceBrowserDelegate { @IBOutlet var scannerView: IKScannerDeviceView

问题 With version 1.1 I don't understand how I can preprocess the original image (by JUST using imagekit) https://github.com/jdriscoll/django-imagekit/blob/develop/README.rst Having a model like this: class Photo(models.Model): original = models.ImageField(etcetera) thumbnail = ImageSpec(etcetera) How do I for instance resize the original image? This was possible in previous imagekits, however the documentation insinuates I need another modelfield? 回答1: You can use ProcessedImageField : from

问题 I am using imagekit to handle custom size of uploaded images. While it works fine for creating custom size images with this, I'd like to use imagekit to resize the original image on upload.

Selecting iPhoto images within a cocoa application

由 ﹥＞﹥吖頭↗ 提交于 2019-12-05 07:14:33
问题 I was wondering what the best way of selecting photos from iPhoto within a cocoa application? Right now, the open file dialogue doesn't allow me to go into the iPhoto library. How can I allow the user to go into that folder? IKPictureTaker was one option, but it appears that it allows the selection of one picture at a time. I'd like a user to be able to select 1 picture, or many. 回答1: Just use NSOpenPanel and set the allowed file types to the public.image UTI: [panel setAllowedFileTypes:
