Image#remap produces unreasonable result

Issue by jxtps
Wednesday Jun 09, 2010 at 02:49 GMT
Originally opened as #8

Image#remap produces an unreasonable result for the attached images. The pixel at 0,0 is remapped from (254, 254, 254) -> (255, 227, 0) despite there being a (255, 255, 255) in the remap_image ("colors" below), which is much closer in RGB space than the color picked.

don't conflate SetImageColorspace and TransformImageColorspace

Issue by smparkes
Sunday Apr 21, 2013 at 23:04 GMT
Originally opened as #75

rmagick is conflating SetImageColorspace and TransformImageColorspace. This is the difference between "convert foo.png -set colorspace rgb ..." and "convert foo.png -colorspace rgb ..."

The former is like a reinterpret-cast in C++: it doesn't change the data, it just says the data is the given colorspace. The latter is a transform that changes the data based on the original image colorspace and the parameter.

I need SetImageColorspace and in the current code, it's not available if TransformImageColorspace is available.

This is a partial patch. I didn't wire in or test image.transform_colorspace(colorspace). If you're interested, I can ...

Problems installing with homebrew (and not macports)

Issue by tute
Tuesday Apr 19, 2011 at 21:24 GMT
Originally opened as #24

I hardwired the following to be able to install rmagick, since I don't have Macports:

$ sudo ln -s /bin/mkdir /opt/local/bin/gmkdir $ sudo ln -s /usr/bin/install /opt/local/bin/ginstall

Because I've seen in lines 85 and 86 of ext/RMagick/Makefile:

MAKEDIRS = /opt/local/bin/gmkdir -p INSTALL = /opt/local/bin/ginstall -c

Shouldn't the Makefile test if /opt/local/bin/gmkdir and /opt/local/bin/ginstall exists?

could/should cycle through converts

Currently on windows if I have more than one "convert.exe" in the path, it might be nice to try each of them until it can hopefully find one that works :)

Resolution management

Issue by daniel2d2art
Saturday Feb 11, 2012 at 21:40 GMT
Originally opened as #46

I've next resource:

file: 300dpi.jpg
dimensions: 1782px x 1181px
size: 304539 bytes
resolution: 300dpi x 300dpi

when I use:

image.resize_to_fill!(460, 345)

I get:
file: 300dpi_conversion_1.jpg
dimensions: 460px × 345px
size: 21718 bytes
resolution: 300dpi x 300dpi
Result: Ok expected

Now I want to try reduce the resolution, I use:

image.density="72x72"
image.resize_to_fill!(460, 345)

I get:
file: 300dpi_conversion_2.jpg
dimensions: 460px × 345px
size: 21718 bytes
resolution: 72dpi x 72dpi
Result: resolutions seems change but size its the same at 300x300

No I try to reduze adding resample too, I use:

image.resample(72.0, 72.0)
image.density="72x72"
image.resize_to_fill!(460, 345)

I get:
file: 300dpi_conversion_3.jpg
dimensions: 460px × 345px
size: 21718 bytes
resolution: 72dpi x 72dpi
Result: resolutions seems the same 72x72 as above test, but size its the same at 300x300 too

???
How change resolutions works???, I don't get clareance about it on documentation, it's working ok?
How can I upload a image file (JPG, GIF, PNG) optional (TIFF, BMP), and transform they change resolution and resize?

Thanks

Could you please post a binary for ruby 1.9.1 on win32!?

Really, would it be so much trouble for you to please build and post a binary for a current ruby 1.9.1/win32 runtime? Tonight?! Otherwise this is blocking ruby development with 'rmagick' dependencies for a lot of people. I really have other things to do than build rmagick from source right now as I see it doesn't build with mingw! Thanks!

"stack level too deep" when calling Magick::Image.read within a fiber (Ruby 1.9.3-p0)

Issue by mamu
Wednesday Nov 30, 2011 at 01:28 GMT
Originally opened as #38

Hi!

I'm not exactly sure what's going on since I get inconsistent results between my Linux dev box and my OS X dev box, both running the same version of Ruby (1.9.3-p0), both using rvm, both running the same version of RMagick (2.13.1), and both running the same version of ImageMagick (6.7.1, compiled from source).

My OS X dev box plays along nicely, but my Linux dev box throws a "stack level too deep" exception when I call Magick::Image.read within a fiber. I'm using the fiber to untangle evented code in a fashion quite similar to igrigorik's em-synchrony project), so this is all being done within the context of EventMachine's event loop. If I downgrade to Ruby 1.9.2-p290 on my Linux box, RMagick begins to work fine again.

Really at quite a loss why OS X would behave but Linux wouldn't. I don't know what else I ought to provide to help track down the issue, but I'd be happy to post anything extra anyone requests.

Thanks!

support for ImageMagick morphology option

Issue by goodwillta

morphology option is powerful and extremely handy, and has been available since ImageMagick 6.6.0-1. Are there any plans to include the option in rmagick? It would be greatly appreciated.

uninitialized constant Magick::Hatchfill (NameError)

Issue by jadiaz
Thursday Sep 30, 2010 at 22:52 GMT
Originally opened as #17

Having installed and verified ImageMagick I downloaded the latest gem for RMagick. I wanted to make sure that the RMagick installed correctly so I ran the following script:

require 'rubygems'
require 'rmagick'

canvas = Magick::Image.new(240, 300, Magick::Hatchfill.new('white', 'lightcyan2'))
gc = Magick::Draw.new

gc.fill('red')
gc.stroke('blue')
gc.stroke_width(2)
gc.path('M120, 150 h-75 a75, 75 0 1, 0 75, -75 z')
gc.fill('yellow')
gc.path('M108.5,138.5 v-75 a75,75 0 0,0 -75, 75 z')
gc.draw(canvas)

canvas.write('path.png')

No matter what I do (uninstall gem, install via tarball) I get the Hatchfill error.

Removed the SplineInterpolatePixel check

Hi Guys,

In a commit in June 2009 a check in the extension config was removed relating to SplineInterpolatePixel and InterpolatePixelMethod. I noticed, after a fair bit of hunting, that the check regarding this enum was not removed in the rmmain.c file, so in the end SplineInterpolatePixel is never made available.

Here is a small patch which removes the check and makes SplineInterpolatePixel available for all :)

Thanks for the great gem!

Can't install rmagick

I am trying to install rmagick on a shared host. I don't have root access.
But I can compile things.

I compiled ImageMagick like this:

./configure --prefix=$HOME/bin --disable-static --with-modules --without-perl --without-magick-plus-plus --with-quantum-depth=8 --with-gs-font-dir=$FONTS

Then I exported the paths and tried to install the gem:

export LDFLAGS="-L/home/dorfbran/bin/lib" 
export CPPFLAGS="-I/home/dorfbran/bin/include/ImageMagick" 
gem install rmagick

This is the resulting error message:

Whether from rails, script, or irb, anytime I attempt to even open an image the process locks up. It does not even respond to ctrl-c. I have to force quit it. I compiled ImageMagick with --disable-openmp and convert works as expected from the command line. Is this a known issue?

ImageMagic installed via Homebrew doesn't work

Issue by jkamenik
Thursday Dec 01, 2011 at 18:55 GMT
Originally opened as #39

I use a Mac, and homebrew for many packages including ImageMagick. I noticed a very annoying issue that I had to work around. Homebrew symlinks to /usr/local/bin and /usr/local/include. For example: /usr/local/include/ImageMagick -> /usr/local/homebrew/.../ImageMagick. This works fine with most libraries that need imagemagick since Magick-config produces the correct paths to the symlinks and the compilers just follow the sym links.

The rmagic gem compile does not seem capible of following symlinks and therefore cannot find /usr/local/include/wand/MagickWand.h which is there.

$ gem install rmagick

My solution was to install ImageMagick via https://github.com/maddox/magick-installer/blob/master/magick-installer.sh, which doesn't use symlinks. Without symlinks things work fine.

You can see the log here http://pastie.org/1256503

Why isn't there an unsharp_mask!

To do it in place, is this the usual way:

ImageList destroy!

Issue by mmb
Saturday Feb 18, 2012 at 05:37 GMT
Originally opened as #47

It looks like if you call destroy! on an ImageList instance it destroys only the last image in the list. If this is the case other people might make the same mistake I did and not be destroying what they thought they were.

Should ImageList.destroy do

il.each { |i| i.destroy! }

Annotating fails when '@' is first character

Issue by VxJasonxV
Thursday Nov 08, 2012 at 10:44 GMT
Originally opened as #59

I had a script in use for years that would record data from Last.fm, and build an image out of various song information.

Some time ago, on the order of months, this script would keep showing the current song being played, but would simply stop working when showing historical playback data.

After poking around, it appears that this was due to a leading @ character when using the annotate method. The rest of the data following the at-symbol does not appear to have any affect.

When invoked, Ruby would return this information:

bin/lastfmsig.rb:14:in `annotate': no text (ArgumentError)
        from bin/lastfmsig.rb:14:in `text'
        from bin/lastfmsig.rb:42
        from bin/lastfmsig.rb:37:in `each'
        from bin/lastfmsig.rb:37

shell returned 1

Changing the first three characters to be " @ " (space-at-space, really any character leading besides @) appears to have fixed this issue.

Converting JPEG from RGB to CMYK results in segfault

Issue by meanphil
Tuesday Jul 10, 2012 at 23:27 GMT
Originally opened as #55

Trying to save any image as a CMYK Jpeg will result in a crash. If you change CMYK to any other colorspace such as RGB, CMY, or Gray it writes the image OK.

My test script is as follows:

require 'rubygems'; require 'RMagick'

i = Magick::Image.read('test.jpg').first 
i.write("cmyk.jpg") do |ii|
    ii.format = 'JPEG'
    ii.colorspace = Magick::CMYKColorspace
end

$ ruby test.rb 
test.rb:4: [BUG] Segmentation fault

gdb says the segfault is in ImageMagick here:

0x0000000803642ef7 in WriteJPEGImage (image_info=0x80386f000, image=0x803859000) at coders/jpeg.c:2604
2604                  *q++=(JSAMPLE) (ScaleQuantumToChar((Quantum) (QuantumRange-

However the following command line works fine, so it must be something that RMagick is (not?) doing:

convert test.jpg -colorspace CMYK cmyk.jpg

Environment is Ruby 1.9.3-p194, ImageMagick 6.7.7-7, RMagick 2.13.1, FreeBSD 8.2, gcc 4.2.1

RMagick 2.13.2 on Windows 7 x64

Issue by bodrovis
Monday Feb 04, 2013 at 11:24 GMT
Originally opened as #66

Hello. I just noticed that RMagick was updated to 2.13.2 and that it should support ImageMagick 6.8. So i uninstalled my old ImageMagick, downloaded a new one (6.8.2-3-Q16-x64-dll) and installed in with C/C++ headers. Then i tried to install RMagick using instructions found in the Wiki (it helped me to install rmagick 2.13.1), but got the following error:

======================================================================

Exactly the same error i got when trying to use ImageMagick x86. My Ruby version is 1.9.3-p374. I recall, that when trying to use ImageMagick 6.8 with older rmagick 2.13.1 i got the same (or near the same) error about conflicting types.

Any clues about this issue?

Rails 3 Development mode crashes after the first usage of ImageMagick

Issue by jeffdeville

I think what's happening is that in development mode, Rails tries to clear itself, and reload the environment somewhat after each page. It's this process that is dying.

this doesn't work,

this works

image = Magick::Image.new(100,100)

Why can't the colorspace be set during the block? Is this a bug or intended (if so, why?).

Ruby 2.0 warnings

Issue by dicom

Originally opened as #69

Hello

I just tried installing the RMagick gem on the newly released Ruby 2.0.0 on Windows XP 32-bit (using DevKit), and it seems to produce several warnings while building the documentation. These are probably related to the fact that Ruby 2.0 has switched default encoding from ASCII-8BIT to UTF-8. Although RMagick seems to work fine after the install, I still think these warnings should be eliminated, to avoid alarming the user.

Here's the installation log:

RMagick thumbnail doesn't work like ImageMagick thumbnail

Issue by mattneub
Tuesday Aug 16, 2011 at 00:47 GMT
Originally opened as #33

In ImageMagick I can say:

 $ convert marcelle.jpg -thumbnail 300x1000 -quality 90  -unsharp 0x.5 marcelle_th.jpg

The -thumbnail 300x1000 part means: resize proportionally, and be smaller than or equal to width 300 and height 1000. In other words, 300x1000 represents a maximal bounding box.

But in RMagick, pic.thumbnail(300,1000) does not resize proportionally - instead, it makes an image whose size is exactly 300x1000.

Of course I can work around this by using GreaterGeometry and change_geometry, but my point is that having to do so makes thumbnail kind of useless. So I suggest that the lack of match between ImageMagick's thumbnail behaviour and RMagick's thumbnail behavior is a possible bug.

vector density on read

I'm trying to convert a vector image to a raster image of a larger size, let's say 4x larger. Suppose just running convert img.svg img.png gives you a 100x100 image.

With ImageMagick's convert command, the conversion with enlargement would look like:

convert -density 288 img.svg img.png

Where 288 is of course 4x the default density of 72. And that works beautifully, resulting in the desired 400x400 image without the ugly artifacts you'd get from upsampling a 100x100 raster image to 400x400 (which is indeed why I'm using a vector image for the original in the first place).

But what I would have thought was the corresponding RMagick code:

image = Magick::Image.read('img.svg'){self.density = 144}.first
image.write('img.png')

... results in the same 100x100 image you'd get by just running convert img.svg img.png. Moreover, the image reports its density as "72x72" as though I hadn't supplied anything in read's block.

Am I simply approaching this problem wrong, or this a bug?
