CGPathRef and PDF

It there a way to draw a complex shape with an application like CorelDraw or Adobe Flash, etc, save it or export it as a PDF and then open it with Core Graphics in iOS. The idea is, to draw a shape, a vector, with CorelDraw - for example, and it is just the path. No color or fill. And then be able to open it directly by Core Graphics, add it as开发者_StackOverflow社区 a CGPath to the context, and then be able to manipulate it, like fill it with solid color or gradient, or patterns.

The bottom line is, I am looking for a way to draw a complex shape in a user-friendly environment, like Corel or Flash, and export it, as a vactor, which can be manipulated in Core Graphics. And suggestions or help is really appreicated.

Thanks.

SVGKit doesn't work the exact same as I need either. Although I should say it is nicely done. There are also other resources, that I found and I'll leave them here for future references, if anyone stops by this post and is looking for a solution.

Converting SVG Paths to Objective-C Paths Good for simple paths; strokes and fills can be manipulated later by using protocols. Complex paths get mixed up.

SVGKit Good for creating images and animate them later through the course of the program. However, strokes, fills, paths can not be manipulated.

Opacity You can export as source code, hence you have more control over strokes, paths, and fills. As the path gets more complex, it is harder to manage the code manually. The other problem is by the time of export, the program adds resolution-dependent codes. It can be a pain to go through about 300+ lines of code to fix it so that it is not resolution dependent. By the final product wouldn't be mixed up, and can be manipulated by protocols. Layers are CGLayers, not CALayers.

If, as you say, you've got PDF files (from Corel, or another app), you can display them using CoreGraphics.

Take a look at the:

• CGPDFDocument class
• CGPDFPage class

Then, there is a CGContextDrawPDFPage function, that you can use to draw a PDF pages in a given graphic context, typically in the drawLayer: inContext: method of a UIView subclass.

There isn't really a built-in way to load CGPaths from files but you might want to take a look at SVGKit. Pretty much every modern vector drawing app can produce SVG files.
