(Has anyone thought of using the examples pages etc as a regression test suite? Then new releases could be readily tested for breaking old functionality.

Just a thought, and probably a stupid one.)

I like the look of the 180. But, what is the artifact that will be added to the photos with color saturating like this? I'm not sure I understand the question. The command will increase colour saturation: dull colours will become more intense, without changing hue or lightness much. But greater val...

On Windows 7, IM 6.6.0-8, I get the same problem.

Follow the instructions at http://www.imagemagick.org/script/binar ... hp#windows

You just download and run an installation file.

"-crop" will crop images.

ImageMagick manipulates raster images, so it converts any text to raster (ie pixels). If you want to crop a PDF file while retaining text as text, ImageMagick can't do this (as far as I know).

ImageMagick is aimed at people who aren't afraid of the command line. For example, to increase the saturation of a number of JPEGs (in Windows): md \moresat cd \moresat copy \mypictures\*.jpg . mogrify -modulate 100,180,100 *.jpg In the above, "180" gives a massive increase, just to be obv...

It's a shame that "-debug annotate" doesn't seem to take shear into account. immortal26: I suspect your concern is in the time required for subsequent processing: writing then processing a text file of a million pixels. If so, you might "-trim" the file, and take note of the canv...

Thinking further, I think the docs say other non-zero values are possible on failure.

returns 0 on success, 1 on failure (eg if the file can't be converted).

Hmmm ... okay. That 45 MB SVG defines a canvas of 1000x1000, and draws a circle radius one on every single pixel. Most are blank, and you are picking out the others, the ones used to draw the font. Looking at final.png with Gimp, I see that each letter is made from dashes, and each dash is 1 or 2 pi...

$final = "convert final".$png." to final.svg";

??

The glare has removed information by burning it out. Some algorithms (not built into IM) can guess what has been lost, based on nearby colors.

Good result. The code looks fine, with the possible exception of the assignment to $final: $final .= $bm.'bm'.$rbm.$png.' -geometry +'.$s['cx'].'+'.$s['cy'].' -composite '; I don't know if php interprets the quotes around cx and cy as you want. I guess it does, or the convert would fail. Yes, you se...

I'm trying to understand, so we can help you. What do you hope to achieve with ImageMagick that you couldn't do with a camera phone in 30 minutes?

The compose method is changed to Copy_Opacity, so that's what the final composite uses. If it should be "compose over", you have to explicitly set it.
