Sorry for the cross post but it occurs in both command line and PHP Imagick
ImageMagick Version: ImageMagick 6.3.3 04/21/07 Q16 (Win32 on Vista x64)
imagick module version 2.0.0-rc1
PHP Version 5.2.4
I have run into a few issues attempting to annotate an 8-bit TIFF file. UsingImageMagick 6.3.6 Q16 with and without imagick. I was never able to get CMYK color values i.e. "cmyk(100%,0,0,100)" for cyan. It interprets the fist three items and uses them in an RGB type color scheme. Instead of cmyk(100%,0,0,0) being cyan, it show up as a true red as would be expected in rgb(255,0,0) represented as C:0%,Y:100%,M:100%,K0%. The test starting file is attached to the PHP post.
Code Below:
Command Line:
convert base-business-card.tif -font arial -pointsize 52 -fill cmyk(255,0,0,0) -draw "text 200 200 'This is a test'" new.tif
PHP Code:
$fontdir = getcwd().'/fonts';
$imgdir = getcwd().'/images';
$imagick = new Imagick($imgdir.'/base-business-card.tif');
$imagickDraw = new ImagickDraw();
$imagickPixel = new ImagickPixel();
$imagick->setImageColorspace(Imagick::COLORSPACE_CMYK);
$imagickPixel->setColor('cmyk(100%,0,0,0'));
$imagickDraw->setFillColor($imagickPixel);
$imagickDraw->setStrokeColor($imagickPixel);
$imagickDraw->setFont($fontdir.'/arial.ttf');
$imagickDraw->setFontSize(52);
$imagick->annotateImage($imagickDraw,200,200,0,'This is a test');
header( "Content-type: " . $imagick->getImageType() );
print $imagick->getImageBlob();
