Re: alpha channel and Fred's Imagemagick Tidbits

Thanks for confirming it's not just me.
And for the pointers to the new features - I'll read up on the. It certainly keeps the little grey cells active.
Cheers,

alpha channel and Fred's Imagemagick Tidbits

I'm trying some commands from here: http://www.fmwconcepts.com/imagemagick/tidbits/image_info.php#alpha and they don't seem to work as per Fred's examples. Is Fred wrong or is ImageMagick broken?

Re: Need Depth 8bit Red/Green/Blue 1-bit, Alpha 8-bit png. H

Thanks Fred - noted.
Think I'll need to check a few scripts I have - I don't think I've consistently done that. Haven't noted any problems, however.

Need Depth 8bit Red/Green/Blue 1-bit, Alpha 8-bit png. How?

I'm using a program "Seam Carving GUI" that can save .png files of its masks. The program can also read in masks. There are 2 types of mask - in appearance they are either green or red images on a transparent background. Created my own mask using gimp but it isn't recognised properly by th...

Re: Converting from PDF to JPG

Hi,
Don't know about the php bit, but I can confirm that from a command line:

Code: Select all

convert -density 100 -colorspace rgb test.pdf -scale 200x200 test.jpg
works OK for me with gs 9.00, ImageMagick 6.6.6-9
Do you see any useful messages if you run it from a command line?
Cheers,
Peter

The commands are: composite -compose Src -gravity center 03_active-highlight.png bg_canvas.png highlight.png # highlight.png from above is then used in the command below. Of course, if highlight.png is bad, then result.png is bad too. # On my web pages I put the ImageMagick version into the filename...

Re: PDF TIFF conversion

Hi,
Do you have ghostscript installed? I believe ImageMagick needs it to handle PDF.

Re: ebook distortion

All pages would have same distortion, so once I find the algorithm for first pages, it will be ok for all of them. Gwenview (Linux viewer) displayed a thumbnail image of your book in which I saw it being held between two hands standing on a table. I was thinking that it would be difficult to make t...

Re: ebook distortion

Out of curiosity I tried to remove the distortion using Hugin as per the tutorial http://hugin.sourceforge.net/tutorials/perspective/en.shtml Somewhat successful. It might have been better if I'd had the page edges to use for control points. Probably useless for batch processing if you're trying to ...
