In Procreate, you can edit lines by using the Transform tool. First, select the layer containing the lines you want to edit. Then, tap on the Transform tool icon and use the handles to resize, rotate, or move the lines. You can also use the Warp tool to distort the lines or the Liquify tool to push and pull the lines into different shapes. Additionally, you can adjust the opacity, blend mode, and other settings of the layer to further edit the lines. **

The image in Procreate can remain sharp when zooming in because it is a vector-based program, which means that the image is made up of mathematical equations and points rather than pixels. This allows the image to be infinitely scalable without losing quality. Additionally, Procreate uses advanced rendering techniques to maintain the sharpness of the image even when zooming in, ensuring that the details and edges remain crisp and clear. Finally, Procreate also supports high-resolution canvases, which further contributes to the sharpness of the image when zooming in. **

Procreate uses a feature called "canvas acceleration" to keep the image sharp when zooming in. This feature dynamically adjusts the resolution of the canvas based on the zoom level, ensuring that the image remains crisp and clear even at high magnifications. Additionally, Procreate's advanced rendering engine optimizes the display of the image, maintaining its quality regardless of the zoom level. These technologies work together to provide a seamless and high-quality drawing experience in Procreate. **

To export in Procreate, you can simply tap on the wrench icon to access the Actions menu, then select "Share" and choose the format you want to export your artwork in, such as JPEG, PNG, or PSD. You can also choose the resolution and quality of the export. Once you have selected your preferences, you can then choose where to save the file, such as to your device, cloud storage, or to share it directly with others. **

As of my knowledge cutoff in September 2021, Procreate costs $9.99 USD as a one-time purchase on the App Store. However, prices and subscription models can change, so it's best to check the current pricing on the App Store or the Procreate website for the most up-to-date information. **
