image-formats

I often use JPEG images, and I have noticed that there are two very similar file extensions: .jpg , which my mobile's camera and the Preview application use, and .jpeg , with which Image Capture saves the images from scanning with my Canon MX455 printer. LaTeX doesn't seem to distinguish, as I gave it a .jpeg with the extension changed to .jpg and the result seems to be the same as if it had been a .jpg right from the start. I have wondered what the difference between the two is. I have come across this question , and will certainly read through it, though at the moment I'm slightly out of

JPEG, GIF and PNG can be displayed with the img tag and will work in all browsers, the object element can be use for displaying images specifying its MIME type, but what other graphic formats are supported by img or object tag in most browsers without installing plugins? (TIF, SVG, PCX, PICT, etc..) ConroyP There's an excellent chart on wikipedia that lists common image types and their support by browser. The file types you listed (jpg, gif and png) seem to be the main formats supported by nearly every browser, albeit with certain caveats: Internet Explorer supports PNG images but is unable to

I am trying to add a image to a RTF document which I am creating. I would prefer to not use 'copy/paste' methods (that involve pasting the image within a RichTextBox and then accessing the .RTF property) which purge the clipboard (as this will be a bother and confusion for my end users). The code I have so far returns the string that needs to be inserted into the RTF document to print the image. The inputted image (located at $path) is usually in bmp or jpeg format, but at this stage I am not concerned with how the image is stored within the RTF only that i can get it to work. public string

Is it possible to find out the type of an image encoded as a base64 String in PHP? I have no method of accessing the original image file, just the encoded string. From what I've seen, imagecreatefromstring() can create an image resource from a string representation (after it's been decoded from base64), but it automatically detects the image type and the image resource itself is a special PHP representation. In case I want to save the image as a file again, I would have no idea if the type I am saving it as corresponds to the original type from which the String representation was created.
