Background Transparent – help!

"djmasala.com" wrote in message

Hi,
I’ve just started to use PhotoShop 7.01, and want to know how to make the background transparent? I selected Transparent from the Contents box when making a new file, but when I save it as a JPG, it always has a white background. Can anyone help??

Thanks…

JPG does not support transparency. Only the .gif format supports transaprency…. (Believe the .png does too but i don’t know too much about it.)

Err, that is not an absolute truth!

Depending on the program you’re going to use it in, JPG-pictures with a clipping path give a 100% transparency. It works in the e.g. InDesign and RagTime DTP progs.

The advantage of JPG over GIF is the reduction in bits at a comparable picture quality.

Mmmm… as far as i’m aware, JPG does not allow for transparency…. you can have a background colour… that merges with existing background… but transparency? No.

Can’t you read?
Maybe you do not know what a JPG picture with a clipping path is? As I wrote, it DOES work in e.g. InDesign 2 and in RagTime. I did and tested it myself and I did see and printed the result!! 100% transparency!!

At the placement c.q. import of such a JPG picture it even shows the recognition of the PhotoShop clipping path.
That there is either a single colour background or even the original picture outside the clipping path makes no difference. In the DTP progs everything outside the clipping path is treated as transparency.

Perhaps you should try it too before you put a silly comment in this newsgroup.

Perhaps the poster was assuming, as I did, that the original post was referring to the use of transparency with a JPEG in the context of the web, not printing. After all, most people serious about quality commercial printing use clipping paths in conjunction with TIFFs, not JPEGs.

With PNG support erratic, GIF is the only file format that will reliably display transparency in a web browser.

The clipping path is not part of the official JPEG specification; most applications can’t read a JPEG with a clipping path.

In any event, it certainly won’t work on the Web, and JPEG is not really an appropriate image format for print.

Thanks, never knew that, works perfectly! (tried with InDesign 2 and Photoshop 6)

Depends on the contents of the image, I have many, many examples where JPEG is both bigger and has less quality (screenshots for example).

But to come to the point of the original poster: JPEG and transparency is not supported by a browser I am aware of (would be fun, clipping path support in a browser…).

Usually this question refers to using JPG images on a website. JPG images with a clipping path are not what one expects when talking about JPG images – and I’d bet large amounts of money that none of the four most used web browsers supports clippping paths.

The advantage of JPG over GIF is the reduction in bits at a comparable picture quality.

When using photographic (as P in JPEG) images, yes. When using graphics with only a few colors (<256) but sharp borders JPG compression has to be reduced (for quality) that GIF can be the format of choice – but then, PNG compresses better 🙂
