bug report: hex color codes in fx expressions

This works:

Code: Select all

convert -size 100x100 xc:  -fx "#cccccc" x:
But this produces an error:

Code: Select all

convert -size 100x100 xc:  -fx "#cccc6c" x:
convert: unable to parse expression `#cccc6'.
Numbers in hex codes break parsing.

Using Imagemagick 6.3.0 11/07/06 Q16 with Debian.

Also `keep' is not a valid argument to -density. See http://imagemagick.org/script/command-l ... hp#density

Too many hyphens in "--density".

The alpha channel is correctly empty in the left zone. The color channels do have color data in some of the transparent areas, as shown with -separate. There are a few pixels in column 0 whose alpha value differs, as you can see with: convert upgrade_sound06.png -crop 1x600 txt: | less You can over...

You need quotes around Times New Roman so that the shell will treat it as a single string.

I don't know the answer to your question about why some fonts cannot be found. I have that problem too.

Only by giving up transparency. Gif supports only binary transparency, so you cannot blend a color with transparency. If, however, you know that the gif will be displayed on a white background, you can get an antialiased effect with a command like the following. But now white jaggies will show up if...

feature request: splicing with transparency

Hi, I would like to be able to -splice with a transparent color when the image I am operating on does not necessarily already have an alpha channel. What are your thoughts on this patch: http://jjfoerch.com/bitbucket/splice-transparency.diff --- ImageMagick-6.3.0/magick/transform.c 2006-07-03 13:23:...

Actually this file is 16 bit unsigned fits file, so that DATAMAX header is correct. I found the following link that explains how unsigned data types are supported by FITS. http://heasarc.gsfc.nasa.gov/docs/software/fitsio/c/c_user/node22.html So ImageMagick should look at the BSCALE and BZERO header...

ImageMagick and FITS

Can anybody show me how to do anything at all with FITS files? Convert and Display treat my files as being completely black.
