CodePudding user response:

Don't know what is your demand. PDF: why do you want to convert images?

I guess you should be your winform read PDF and display?

In this case I think convert PDF to image is not a good solution.

If it is me.. I will use some js components to realize such as PDF. Js these.

When the UI rendering you can set a browser controls to display these things than your own conversion easier..

This solution is more extensive.

Such as you want to achieve some graphical control under the Windows graphics or less and also not convenient.

Many people like to use every so this way is more appropriate.
