You know those fancy scrollbars that allow you to resize images? Well, the UiImageResizable class provides it, and it makes it quite easy to resize an image. It is especially nice when you have to go back and forth between two images that you’ve already resized to a certain point, which is pretty convenient.
Now that’s what makes it a lot easier to use than the fancy resizable class, of course.
But don’t take my word for it. Take a look at our gallery of all the images in our UIImageResizable demo.
If you’re ever confused about how to put an image in a scrollable UIImageView, just look at our gallery of images in our UIImageResizable demo.
Yeah, that is pretty cool, but it does have a downside. If your image is going to be resized, but youre going to have to set its context to 0x0, you will have to set it to a non-zero value.
Context isn’t something you can change, it’s an automatic setting in UIImageView. That means that if your image is going to be resized, you will want to set it to 0x0. There are two ways to do this. The first is just to set it to 0x0, but that will have the unfortunate consequence of causing it to stretch across the width of the UIImageView. The second is to set it as an alpha value to 0.
The first is what we are doing. So setting the image to 0x0 will cause the image to stretch across the width. The second is a little trickier. The alpha value will make the image appear to be transparent. So 0.5 will make the image appear to be transparent, but 0.0 will make it completely opaque.
This is more like a bad joke or an example of what does exist. We use the term “valid context” to mean context to the image and the width of the image. We often use the term “context” to refer to the context of the image, but we do it in various ways. For example, we often use the context of the background to determine the context of the image itself.
I think it comes down to a philosophical question. Can you have an image that is both transparent and opaque, or can an image be both transparent and opaque? I don’t think the answer is “It depends.” One of the most famous examples of a context that’s both transparent and opaque is the Star Wars universe. The original trilogy of movies had a lot of things that were both transparent and opaque.
