Create around 50 images in Corel Draw

I have a set of images as bitmaps in low resolution? and size? and would like to print them in large size and high quality. However, after the images are increased, prints are pixellated. I would like to recreate bitmap pictures as vector images to be able to print them in any size in high quality. Corel Draw seems to be the best choice, however, you are welcome to advise. ## Deliverables All images are relatively simple. I am attaching a couple of typical images.
