However, since corelDraw is a vector program, you'd prolly have more luck in Illustrator with maybe an .eps file type. Not sure on this, though.
As it was stated what I have quoted. Yeah if you do have adobe illustrator you can work back and forth through illustrator and photoshop. It really comes in handy when working on projects that require vector fields and if you dont know much illustrator then you can bounce it into photoshop, I dont think you need to save it actually, if I remember correctly just click the layer in illustrator and drag it to the taskbar where photoshop is and wait for it to pop up and then release it inside of photoshop and it will appear as a vector layer object as if were drawn with the pen tool. But it is better to save the project file and then go back and forth between just so you always have it available again. Which you can open eps files inside of photoshop.
