I would like to repeat a watermark with imageresizer so that the background of an image is seemlessly filled with a background tile.
I don't find a way to so this in the docs. Is that even possible?
No, this feature isn't supported. You could create a plugin that tiles an image on the background pretty easily, though - inherit from BuilderExtension and override PostRenderBackground.
Why not use CSS, though?

Are there any plugins for ImageFlow.NET that enables me to auto crop images to focus on objects, not faces, in them? Or any other non-plugin way to do it with ImageFlow.NET?
Not yet, but it is something we're planning to add. In the meantime, you could try using https://github.com/softawaregmbh/smartcrop.net to get the crop coordinates then feeding them to Imageflow. It looks like a slow library, and the built-in encoding and resizing is very poor, but if you only use it to get coordinates you should be fine.
I'd like to have a background image in the NSSavePanel which I need to satisfy macOS Sandbox file export requirements. Such background image would be reflective of the overall imagery I use in the other application window and sheets. Apple's default NSSavePanel image style is okay for an app that cares little about its style, but my app is directed to video editors who can appreciate an artistic rather than mechanical atmosphere.
I've been able to use the panel's accessoryView property but it only appears as a differentiated section in the panel separate from the panel's overall style.
A simple background image for the panel overall capability would completely suffice, but it doesn't seem possible according to all the Apple Developer documentation. Maybe there's a practical HACK?
I'm wondering if it's possible to have a slide with text AND add some animation into it for an iPad app. See screenshot below to get an idea of what I need. I want that guy jump up and down and smile. I'm sure I'm not capable of drawing that image using Objective-C primitives myself, so I'm looking at the following options:
Do complete animation in 3rd-party tool (Adobe?) and then add it as single standalone file on the slide. But I do not know, what formats are supported in iOS, what are standard formats, and, at the end, how to insert that file on the slide. Can somebody clarify this please?
Do complete animation, and then save frames as images, and then quickly change images to give illusion of a movie.
Am I missing something? Are there any other ways? what's the best option?
Please let me know if I'm not clear enough - I will try to provide more information.
Thank you.
If you want to use a movie file for the animation, you can find the supported video formats in the iOS Technology Overview, under “Media Layer > Video Technologies”. You will need to use an AVPlayerLayer from the AVFoundation Framework to show the video.
If you want to use a separate image file for each frame, you can use one of the +[UIImage animatedImage...] methods to create an animated UIImage, and display it in a UIImageView.
If you want to use a single animated GIF for the animation, you can use this public domain UIImage+animatedGIF category to load the GIF into an animated UIImage, and display it in a UIImageView.
Like in Photoshop and many other painting/photo editing program that it lets you set the hardness of the brush.
Is it possible to do this with core graphics? Or I have to use OpenGL
PS. If I have to use OpenGL give me some codes and more details.
try CGContextSetShadowWithColor. The Shadow opacity depends on the shadow-color and the opacity of the drawn object. I believe applying a shadow to a full-tranzparent object is not possible without some masking.
... damn i wanted to add a new comment...
I have implemented a scrollview which uses a CATiledLayer. In UIDocumentInteractionController the view shows some kind of checkerboard background while loading its contents. I wonder if there is something similar to UIColor.ScrollViewTexturedBackgroundColor to get this checkerboard? Or do I have to use my own image?
No, there's none in the IOS documentation, unfortunately. Apple uses their custom backgrounds on a lot of apps, and in general you just need to create it and load it with the UIColor.FromPatternImage(UIImage.FromBundle("image")) command.
