I am looking for an easy, direct and straightforward way to render a CGPDFPage and view it on an iOS device.
The rendered page should fill the view to which it is drawn and be crispy clear.
The less the code used in the method the better. However, if the amount of code required for the best result is too much, then it is preferred that the code be organised and well written.
Please do include a way to view in RGB color instead of CMYK.
I'd really appreciate it if you didn't suggest PDF readers/viewers or Github projects since I prefer not using them.
Thanks in advance.
I don't think this is a valid question. Anyways you should take a look to apple sample codes first.

I want to create some objects (boxes, cylinders, pyramids, doesnt really matter) which display text / a number on the side / on all of it's sides. Short of making individual materials with the numbers displayed on them by hand, is there a simple way to achieve this?
I am using Swift 4 in XCode.
First thing, please try not to be discouraged. Thank you for reaching out to the ARKit community on stack :-)
We are here to help each other.
(I do feel your pain…and why I am trying to help)
Here is an interesting stack page that has helped me with placing items on the sides of objects(like boxes cylinders, pyramids).
I hope it can help you or others.
SCNBox different colour or texture on each face
Rickster pointed out some other possibilities.
We all learn by sharing what we know.

Depends on what you mean by "by hand". If you want the text displayed on the surface of the geometry, like a texture map, then texture-mapping it is the way to go. If you draw your text into a UIImage, you can set that as the material contents, which is a bit more dynamic than, say, creating a bunch of PNGs that each have a different number on them. Just make sure to choose an image size/resolution that looks good at the size your objects are displayed at.
For anyone lost in the internet trying to find an answer to this it's stupidly simple. Use SCNText and set it as a node. I just wasted 7 hours of my life trying to make number .dae models position themselves next to each other because there is no mention of this feature anywhere.
I hope I saved you as much pain as I just endured discovering this.
Is there a Windows server with Photoshop running that process all these templates? It just happens too quickly. How did they achieve that?
I've been looking for the answer for quite a long time and didn't find anything worthy.
A way something like this would be done would be to have an overlay template that you'd place your image under and then all of the shading and such would would go on top of it. Then it's just a mater of rotating and skewing the angle of the picture underneath the overlay to get the right perspective. This can be done programmatically in a language of your choice like PHP, Python, C#, etc.
I believe what you're describing may be achieved using the Adobe Photoshop API. Click on try demo and take a look at the various options, including the Smart Object demo.
Sorry if the question sounds noonish, but I couldn't find a clear answer to this: I know it is not possible to prevent a screenshot in iOS, so I was wondering if there is a way to graphically render an image that would make it look different if it was screenshotted. Now I am not asking for a full technical explanation, but I would like to have a pointer in the good direction, like if there is a specific technical term (I looked into watermarking and steganography but didn't really find what I was looking for).
For instance I was thinking about using a filter in-app, but I assume it could also be captured by the screenshot, so I don't really know where to look.
Thanks!
I'm trying to define pixels of an image based on their color code, and display them on command. I've been researching this and can't seem to find information on the subject, I've mostly been pointed towards "Animations" and "Core Image Filters" which isn't quite what I'm looking for. Any information on the subject is much appreciated.

try this sample code of a color picker. one of the views is a plane of continuous colors and is probably what you want. apple has good source code and the swift book is great for avoiding bad questions. you have to watch it as a beginer.too many simple questions on this site and they will block you from asking more.
I have got one image like this
to only black and white colored image.
And I come across this ImageMagick resource
Does this can be used to generate black and white image from the above given image?
Does it is good to use this one?
If it is good one then does there is any documentation or tutorial on "How to use?".
UPDATE
SO GOT THE BEST SOLUTION FROM #ale0xB's SUGGESTION.
No third party api is required for doing this as apple's COREIMAGE.FRAMEWORK is the best for doing what I want to do. It's filters are working like charm :)
Thanks for the suggestion :)
I use this image filter. And it is great in speed and provides great output :)
Why would you want to use imageMagick instead of the standard Core Image to produce black and White images? I haven't used it before, but I doubt it's gonna give a much better performance than the native framework when it's just about creating a filter.
Since iOS 6 you have it really easy, have a look: Core Image filters, specially to CIColorMonochrome, which is the one you may be interested in.
If you're playing with images in your app, this is definitely worth checking: Core Image Programming Guide
