I need a program to edit text in a Jpeg file. Which software is the best?
If by editing a text in a .jpeg file, you refer to editing an existing text from a .jpeg file, you will have to use an Optical character recognition software(OCR), such as ABBYY FineReader, http://abbyy-finereader.software.informer.com/ This kind of application is capable of reading the text from any jpeg file, allowing you to perform further adjustments over your document.
Most of the existing picture editors will allow you to apply text over a graphic file. You can use a simple picture editor, such as Paint, or something more feature-rich, like Adobe Photoshop http://adobe-photoshop.software.informer.com/ If you are looking for something complex, Adobe Illustrator is an application you can rely on, because it offers a wide range of sophisticated vector drawing tools. Adobe Illustrator helps you create distinctive vector artwork for any project.
