What software is cdr?
Cdr and photoshop are both drawing software, but the difference is that photoshop belongs to bitmap software, and the image is composed of pixels, that is, a small white square that appears after enlargement, with deep and shallow serrated edges, which will be blurred after enlargement and reduction. This has caused a series of problems such as blurred image edges, which greatly affected the appearance.
Especially if it is written in Photoshop, once it is enlarged, the blur will be serious.
CorelDraw belongs to vector software, and the edge of the image is smooth. After enlargement, the edge is still smooth and there is no sawtooth. Text input is generally done in CorelDraw.
In the past, this software was very cheap, but after being represented by a company, it rose directly to the sky-high price. I have to say that China people still have a sharp eye for making money.
