I have a pic of 400 pix X 283 pix with a resolution of 72 ppp.

I need resize the pic because its a wire diagram, and its written the description of each wire and object.

I have resize the pic, but i cant see what is written. I fix to 1800 pix and increased resolution to 1200 ppp. But I dont know what i have to do see what is written clear.

I need help. I will add the pic if anybody could helpme because i need resolve more pic with similar diagrams. I use 2020 Photoshop for mac

Did you try to print and scan it at the highest resolution?

Some Imaging software have a 'vectorize' function, did you try this also?

The exact name of what is shown in the diagram?

Do you know the old saying "You can't make a silk purse from a sow's ear?"

Or "Garbage in, garbage out?"

Well, it's the same with Photoshop. Your results are only as good as the quality image you begin with. Taking a low res graphic from the web is NEVER going to give you good results. When you attempt to make it bigger, all it does is enhance the artifacts and remove the details making it worse than what you started with.

Start over with a high res graphic or create one from scratch in Illustrator. Ideally this should be exported to SVG which retains details at any size. You can't do that with raster images like JPG and PNG.

I cant find the diagrams with better resolution, so I use them and i try get what is written or I have nothing. So If anybody could give and advice to see what's written, I would be very grateful.

Its the only i could find neither in other website or libraries. I know poor resolution doesnt help. But its the only i could.

This is like asking how to make chicken soup back into chicken. It can’t be done. It makes no difference that you can’t find an alternative it makes no difference how important it is. Perhaps you can buy a better copy from the copyright holder, and copies on the web are deliberately useless to make you pay.
