sketch's Issues

Cut, copy and paste

Hello, thanks for this awesome library, is it possible to cut and copy a particular area and paste it at other location ?

Feature request: macOS

Thank you for your work.

Please, consider to adopt for macOS.

For android

Is you have your library support for android or do you have any other library like this for android?

cpu is overload to 100% if sketchView is inside scrollView

Feature Request: Sketch pen

I love this library. Thank you so much!

One more cool feature could be a pen-type that uses speed to determine the width to give it that hand drawn look.

Realtime cloning

I know this isn't directly related to the project, but is it possible to trigger cloning of what I'm drawing on one view to another?

Is may be useful in situations where you're trying to write something in bigger letters and it duplicates itself in smaller version.

Thank you :)

Add Text feature

Hello a great new feature can be add text to a specific place (touched)

How to reposition/resize elements using sketch ?

Hi daihase,

Thank you very much for such an awsome iOS library for drawing. i am using this in a real application for drawing. One requirement is to move/resize the elements that are currently drawn on sketchView.

Is this possible in this library ? if not, then can you please provide me some hints/guidelines on how i should proceed.

Thanks.

New Feature: Draw on an image with zoom functionality enabled for the image

Thanks for the library as this library has almost all the features that I need. But I have to draw on image with zoom functionality enabled for the image for better editing experience.
Some issues I am facing:

• How to save an image after editing?
• Erasing functionality erases the drawing and part of the image as well.

Plz help as I am currently working on my project. Thanks.

How can I create a new public function inside SketchView Class

Sorry, could you please tell me the reason why I put new public function inside SketchView class file, the SketchView will not load image (image will be white blank). Did I miss something? Thanks so much.
(in my sketchView)
public func checkPublic() {

}

(in my viewcontroller)
func setupCanvas() {
let url = URL(string: media.url)
let imageV = UIImageView()
imageV.sd_setImage(with: url, placeholderImage: nil, options: SDWebImageOptions.continueInBackground) { (image, error, cache, url) in
self.sketchView.loadImage(image: imageV.image!)
self.sketchView.drawTool = .pen
self.sketchView.lineWidth = 1.0
}
}

Stamp Resize after added

I need to resize the stamp on the screen so I have add gestures(pinch,pan) and a button to confirm when it completed to remove the gestures and get the location of its.

@objc func onAddStampConfirm(sender: UIButton!) {

        //remove gesture
        for subview in sketchView.subviews {
            for recognizer in subview.gestureRecognizers ?? [] {
                subview.removeGestureRecognizer(recognizer)
            }
        }
        
        sketchView.drawTool = .stamp
        self.sketchView.stampImage = imvStamp.image
        let cgPoint = CGPoint.init(x: imvStamp.frame.origin.x, y: imvStamp.frame.origin.y)
        self.sketchView.addStampComplete(position: cgPoint)
 }

And in sketchView class, I've added this to regconize when add stamp complete

public func addStampComplete(position:CGPoint) {
        currentTool = toolWithCurrentSettings()
        guard let stampTool = currentTool as? StampTool else { return }
        pathArray.add(stampTool)
        stampTool.setStampImage(image: stampImage)
        stampTool.setInitialPoint(position)
        finishDrawing()
    }

in touchbegan (case is StampTool) I let it blank.
Thanks

Support Privacy Manifests?

Does Sketch SDK support Privacy Manifest?

Quoted Apple official website

Important
Third-party SDKs need to provide their own privacy manifest files that record the types of data they collect. Your app’s privacy manifest file doesn’t need to cover data collected by third-party SDKs that your app links to.

Sketch SDK is not included in the SDKs that are subject to the privacy manifest and signature requirement, but if you are not using the required reason API, we would like to know if you have any plans to address this issue by stating that you are not using the required reason API (i.e., not including anything in the required reason API).

---

Sketch SDK は Privacy Manifestご対応される予定はありますでしょうか？
Apple公式(日本語): https://developer.apple.com/jp/support/third-party-SDK-requirements/

Sketch SDKはプライバシーマニフェストと署名必須の対象となるSDK には含まれておりませんが、required reason API 等を利用していないようであれば、利用してないことを記載 (何もrequired reason APIに含めない) していただく等の対応のご予定があるかお伺いしたく存じます。

could we add Anti-aliasing to the FillTool

I need to create a circle with eraser

First of all thanks for this great library. I have a query regarding the library.

I need to create a circle with an eraser. But touch delegates are not working with sketches.
This is not an issue this is an enhancement

If I set backgroundColor=UIColor.white for SketchView, I get the wrong drawing when I use drawTool = .eraser

Thanks for your library. When you have time, could you answer me the question - what is the influence of setting backgroundColor of some view to its draw(_ rect: CGRect) function.

Thanks again.

Save images using Sketch

Hey there! Thanks for you awesome job!

I try to build an image editing app using your library. Got a question there: how can I save the image to the gallery after I loaded and edited it in the app?

I tried to somehow get a UIImage object from the SketchView and then save it in a traditional way to the gallery using UIImageWriteToSavedPhotosAlbum, but did not succeed. I don't see any method in SketchView AP for image saving either.

Thank you!
