Graphics for the web: JPG and PNG Files

Written by Richard Lowe

PNG, like GIF, supports lossless compression. This means that unlike JPEG, bits ofrepparttar image are not lost or thrown away whenrepparttar 134639 image is decompressed. This compression scheme is public domain and improved overrepparttar 134640 algorithm used by GIF.

Images inrepparttar 134641 PNG format may be made partially transparent. This is necessary for displaying good looking graphics on a web page.

Finally, PNG supports color depth of 24 bits or greater. This makes it a much better format than GIF for images which must have lots of colors.

An important thing to remember aboutrepparttar 134642 PNG format is thatrepparttar 134643 color pallet is contained withinrepparttar 134644 image. Thus, it's important thatrepparttar 134645 pallet be made as small as possible, containing onlyrepparttar 134646 colors that are necessary to displayrepparttar 134647 image. Most graphics programs should handle this detail for you whenrepparttar 134648 file is saved.

Note that JPG is still superior for large images because it's compression scheme is better suited for that purpose.

In addition,repparttar 134649 PNG design does not include support for animation. Thus, GIFs must still be used for that purpose.

Most ofrepparttar 134650 modern graphics editors support output inrepparttar 134651 PNG format. These editors include Paint Shop Pro, which is my personal favorite.

Personally, I think it's a little early to go and replace all of your graphics with PNG graphics. Support withinrepparttar 134652 different browsers is still very new, and you would be depriving many of your visitors of your graphics by including PNG images. However, in a few years I expect to see this format more and more.

is high as you want your melody to sing out aboverepparttar other parts. If you can't get enough volume, make a copy ofrepparttar 134638 melody on another track. Pan each melody part left and right and volume will be increased. Remember there is no way to add reverb to midi but you can give a reverb effect by making copies of a track and duplicating each track with an increasing delay. 2)Then add quantizing torepparttar 134639 melody. Look atrepparttar 134640 music. If you see eighth notes asrepparttar 134641 fastest note, then quantizerepparttar 134642 track to eight notes. Quantizing is a method pullingrepparttar 134643 notes torepparttar 134644 nearest beat. For example if you quantized an eight note part ofrepparttar 134645 melody to quarter notes,repparttar 134646 melody would be doubled up into quarter notes and wouldn't sound correct. If your timing is poor, you may need to quantize an eight note melody with a sixteenth note quantization. 3)Once you're sure your melody is rhythmically correct and in place. The other music parts can fit into place. It's important though that your initial melody be correct. 4) Next add a bass and drum part. Again it will be important to quantize these parts. The volume should be a bit lower thanrepparttar 134647 melody sorepparttar 134648 melody can sing out. 5) Next add a background part such as voices or strings etc. A good idea is to make a copy of this part on another track. Then pan each of tracks left and right givingrepparttar 134649 background music some depth. Some instruments don't sound as good as others on MIDI. Good instuments to use are piano, nylon guitar, bass, drums,vibes, strings. Instuments that don't sound as good are sax and brass. There are many more ways to achieve great sounding effects in MIDI but it would take a book to write them all down. Remember to keep it simple. Don't crowd your arrangement!
