Adjusting images : Enlarging images by using AI-Powered upsampling
Enlarging images by using AI-Powered upsampling
When you use the PaintShop Pro Resize window to enlarge an image (upsample), AI-Powered options become available. AI-Powered options use artificial intelligence (AI) to analyze the pixels in your image so that newly added pixels provide a crisper more detailed result than standard upsampling methods. This can help you salvage low-resolution images that you might not otherwise be able to use. For example, you might have a photo that has been cropped to an area of interest, but the resulting resolution is too low to print, or you might have older JPEG images that were captured with a low-resolution camera.
Note: GPU Acceleration can sometimes improve the speed performance of the AI analysis. Results will vary according to your computer system, so experiment to see which setting works best.
Note: The maximum pixel dimensions for AI-Powered upsampling is 10,000 x 10,000 pixels—you cannot apply this option if the dimensions exceed the limit (settings are disabled).
* To enlarge an image by using AI-Powered upsampling
Edit tab 
1 Choose Image Resize.
The Resize dialog box appears.
2 Enlarge the image by choosing one of the following options:
By Pixels — lets you specify a size in pixels by typing values in the Width and Height boxes. You can also choose from a drop-list of standard sizes.
By Percentage — lets you change the size by a percentage (of the original) by typing a percentage into the Width or Height box.
By Print Size —lets you specify a size in inches, centimeters, or millimeters by typing values in the Width and Height boxes. You can also choose from a drop-list of standard sizes and set the Resolution value.
Based on One Side —based on pixels, you can specify the size of either the Width or Height and the image will be resized, using the current proportions.
3 Mark the Advanced and AI-Powered Settings check box.
4 Mark the Resample using check box, and in the drop-list, choose AI-Powered.
5 From the Mode area, choose one of the following options:
Photorealistic: Choose this options for photos.
Illustration: Choose this option for drawings and other illustrations.
6 Set the amount of Noise Reduction you want to apply. Drag the slider to the left to maintain finer pixel details; drag the slider to the right for smoother edges.
7 Mark or unmark the GPU Acceleration check box, according to what works best for your computer system.
8 Click OK.
The green progress bar at the bottom of the application window lets you track the progress of the AI analysis.
