Pics done with a 1 or 2 mpx camera or something. How do I remove/reduce noise and smooth out pics?

How do I limit JPG to 256 colors and not blend surrounding colors?

The same technique used by GIF.

If I were to compare a low quality picture of GIF and JPG, the GIF would be sharper and more clear because it does not blend surrounding colors together like JPG does. How can this be achived in JPG?

I tried cat file | convert -size resolution label:@- image.gif and it gave me a very bad result. I can not even make out what it is since it looks like a thumbnail of a text file. I had to use the -size because it is asking for one. And no matter what size I enter, it would still appear as a ...

Need help with shape and text file. I am trying to draw a circle in the background while have text from a text file on the foreground overlapping it. But no matter what I do, the circle always end up on the foreground covering the text. Anyone know the proper code? Again, using a text file. Not ...

Some pictures came out kind of pale. How do I intensify the colors? I want to make it look like it is warm and sunny.

Can IM extract GIF animations into single GIF pictures?

Can IM make GIF animation from single GIF pictures and set a timer on it?

If so, how?

Version 6.3.7.9 When "identify -verbose" is used in an older version, it would give me information on how many colors is used in the file. But in the above version, it no longer gives me a color count. How do I find out how many colors the picture contains? By the way, is there a way (or alternative ...

How are you displayting a GIF animation???

With 'animate' of course.

When the animation starts to play, parts of the animation becomes transparent where there is suppose to have color.

In many command line programs, there are shortcuts of the switches, but in imagemagick, the full switch has to be typed in. i.e. -quality instead of -q. Most of the time, more than one switch is used. Thus making the command line long and more to type. Is there a trick or a script available to make ...

In the original GIF animation, there is no transparancy. But when played by imagemagick, there is transparency in parts of the picture.

Why does this happen?

By the way, why does it take so long to load a GIF animation in imagemagick? While it loads instantly in a browser?

How do I change the preset speed of the animation (GIF)?

Lowering the quality would of course reduce the size. But I asked: How do I prevent it from increasing the size when stripping or cropping? How do I go about discarding these useless stuff and at the same time save a few kilobytes? When it comes to pictures. The least thing to sacrifice would be ...

Yes, JPG. So it is the extra channels that are increasing the size? If so, how do I prevent it from increasing the size when stripping or cropping? Often, I discard useless stuff such as metadata and thick borders. So there is a minor change. But the increase in size is ironic. How do I go about ...

Using the convert command. Sometimes, when I -strip the image metadata, the new image size is larger than the old! How and why is that? Rarely, when I -crop an image, say by 25 pixels, the new image size is larger than the old! How and why is that? Regarding the above, no additional switches were ...
