Set(density,...)

[tomred]

Hi,

ImageMagick 6.6.5-8 Q16

I can't seem to set the density on a tiff image. Here's my code

Code: Select all

...
$image->Read($tif);
$image->Set(units=>'PixelsPerInch');
$image->Set(density=>'300x300');
$image->Set(density, '300x300');  # a little extra nudge
$image->Set(depth=>8);
$image->Resize(width=>$width, height=>$height);
$x = $image->Write(filename=> $new_name);
warn $x if $x

I have moved the order of the Set/Read items around but it hasn't made a difference. Here the output from identify:

• Format: TIFF (Tagged Image File Format)
  Class: DirectClass
  Geometry: 2847x3069+0+0
  Resolution: 72x72
  Print size: 39.5417x42.625
  Units: PixelsPerInch
  Type: TrueColor
  Base type: TrueColor
  Endianess: MSB
  Colorspace: RGB
  Depth: 8-bit
  Channel depth:
  red: 8-bit
  green: 8-bit
  blue: 8-bit
  Channel statistics:
  Red:
  min: 0 (0)
  .....

Does anyone know what might be wrong?
Thank in advance.

Photoshop ignores the normal TIFF format density setting, but reads its own special profile image meta-data if present.
You will need to remove or modify that profile if you want photoshop to see the right density

See, IM Examples, Common File Formats, TIFF
