Automatic cropping tool (C #) for the latest IOS Application Development Icon specifications #),

Early in the past, I developed IOS apps. I used C # To write a simple IOS APP development Icon Type Auto-cropping device for IOS apps, at present, there are more and more screen specifications for IOS devices. One version requires several types of resolution icons, which are hard to generate one by one with PS. If there are changes to the Icon, You have to generate it again, therefore, it is easier for the whole program to do this job.

The idea is very simple, leading to a large image (Note: This figure must be greater than or equal to 1024*1024, because the iTunesArtwork @ 2x specification is1024*1024), Generate a small image corresponding to the pixel, and save it.

First, let's take a look at the current Icon specifications:

Here I use C # To write, mainly considering that the Bitmap class in C # has a GetThumbnailImage () method that can easily narrow down the image. The following is a simple packaging function for image cropping:

/// <Summary> /// method for obtaining proportional scaling images /// </summary> /// <param name = "imgPath"> path of the image to be scaled </ param> /// <param name = "savePath"> zooming the image storage path </param> /// <param name = "format"> format of zooming the image </param> /// <param name = "scaling"> width or height to be maintained </param> /// <returns> </returns> public bool GetThumbnail (string imgPath, string savePath, ImageFormat format, int scaling) {try {using (Bitmap myBitmap = new Bitmap (imgPath) {using (Image myThumbnail = myBitmap. getThumbnailImage (scaling, scaling, () =>{ return false ;}, IntPtr. zero) {myThumbnail. save (savePath, format) ;}} return true ;}catch {return false ;}}

Final run:

Its mute detection function is also very powerful, you can use this function to cut out the unnecessary mute part of an MP3 file. You can use it to fade out or fade in the audio effect of an MP3 file; you can zoom in the volume of an MP3 file with a lower volume, and change the ID tag of the MP3 file.
