Ionic App to replace part of an image with cropped image

Hi, I need an Ionic, Cordova, Angular 4 application that will be used to replace part of an image with a cropped part of user selected image, The application will has the following images bundled with the application <attached with the project> and more will be created later on: Then the application will do the following: 1. Let user choose one of the bundled images (Image 1) 2. Based on the chosen image 1, a part of this image 1 needs to be replaced like in below examples : a. Circle part like in image [login to view URL] (the green area will be replaced with cropped image) b. Square part like in image [login to view URL] (the purple part will be replaced with cropped image) c. Square part like the image [login to view URL] (the white part will be replaced with cropped image and *rotated*) 3. Let user touch to open his gallery or camera and select an image (Image 2) 4. Ask the user to crop this image 2 based on the part that should be cropped from Image 1 5. Replace the part of image 1 with cropped version of Image 2 6. Save the new image in PNG & PDF format 7. PDF should be for printing with high resolution and 300 DPI I am open to add parameters in addition to the input images to make sure this replacement and cropping position is simple and easy like [x,y] of cropped part or width, high if needed an cropping shape. I expect this to be done in Javascript / Typescript and Angular, you can also use some libraries like the below to save HTML as image or save PDF version of the file * For saving HTML to Image [login to view URL] * For saving PDF [login to view URL] A similar example to what I want is [login to view URL] and it is open source here [login to view URL] I prefer to select a freelancer who show he read and understand the project by asking questions or clarifications instead of pasting his bid without any understanding Thanks
