IF you need to use JPG, why not set the compression rate to produce the best image. Software tend to do this differently. When exporting the image within DRAW, the filter for JPG asks for the image Quality. 100 is the max. quality for the image. This will produce an image with very little, to none, loss of image quality. I have used this 100% quality or 0 compression options to create a JPG file that will be used for re-editing or the highest quality images for detailed photo effects. Some of the best "high quality" file formats will include TIFF, but some software list options to allow compression in TIFF. If you can use TIFF without any compression, that may be the best but some software applications no longer supports TIFF for an acceptable input file. Most Web browsers do not support TIFF images well.
The use of the PNG file format is also an option, but along with the support problems with TIFF, there are some applications that do not like PNG. I tend to take any PNG files and convert them to "high quality" JPG files if the software requires the PNG file format for the exporting file. I have used too many software packages that do not support input of anything but JPG and GIF file formats. So as told by the last thread, TRY a few file formats and see what works best for your needs. If it is PNG, then use it. If it is JPG @ 100% quality and no loss of image quality, then use that. Use what works best for your needs. --------------------------------------------------------------------- To unsubscribe, e-mail: [email protected] For additional commands, e-mail: [email protected]
