IE6 - can't load a normal JPG

只谈情不闲聊 提交于 2019-12-01 15:41:54
Try loading this normal .jpg file in Internet Explorer 6.0. I get an error saying the picture won't load. Try it in any other browser and it works fine. What's wrong? The .jpg file is just a normal picture sitting on the web server. I can even create a simple web page: <a href="http://www.zodiacwheels.com/images/wheels/blackout_thumb.jpg">blah</a> and use right click + save target as with IE6 to save it to my desktop, and it's a valid JPG file. However, it won't load in the browser! Why?! I even tried checking the header response and MIME type and it looks fine: andy@debian:~$ telnet www

NEED HELP! I create a cmyk image by php imagemagick, but cmyk color is different on photoshop! e.g.: set ImagickPixel color cmyk(0,0,0,100)(black), but found cmyk(61,61,61,0) on photoshop. why? and how to set the correct cmyk color? You need to set the colorspace to CMYK, other wise your pixels will be converted to RGB. $img->setImageColorspace(Imagick::COLORSPACE_CMYK); http://php.net/manual/en/imagick.setimagecolorspace.php Also all make sure that you are using file type that supports CMYK. ( eg. .jpg, .tif ) Edit It seems Imagick has a bug. Until it is fixed you can try and use this work

SVG image with CMYK colours - is it possible?

倖福魔咒の 提交于 2019-11-30 04:56:38
Is it possible to specify that as SVG image should produce output in CMYK? If so, is it a big task? What if the image has its colours specified in RGB, is it difficult to convert them to CMYK? SVG supports ICC colors, using ICC color profiles , which would let you do what you need, but it's not yet supported by any browser :( SVG 2.0 adds support for unmanaged colors allowing you to specify a CMYK color with an sRGB fallback: <circle fill="#CD853F device-cmyk(0.11, 0.48, 0.83, 0.00)"/> You can also use icc-named-color() to specify a spot color which would be defined in a linked ICC color

Pure Java alternative to JAI ImageIO for detecting CMYK images

心不动则不痛 提交于 2019-11-30 03:41:41
first I'd like to explain the situation/requirements that lead to the question: In our web application we can't support CMYK images (JPEG) since IE 8 and below can't display them. Thus we need to detect when someone wants to upload such an image and deny it. Unfortunately, Java's ImageIO won't read those images or would not enable me to get the detected color space. From debugging it seems like JPEGImageReader internally gets the color space code 11 (which would mean JCS_YCCK ) but I can't safely access that information. When querying the reader for the image types I get nothing for CMYK, so I

UIColor CMYK and Lab Values

走远了吗. 提交于 2019-11-29 23:06:34
问题 Simple question, more than likely complex answer: How can I get CMYK and Lab values from a UIColor object (of which I know the RGB values if it helps)? I have found this regarding getting CMYK values but I can't get any accurate values out of it, despite it being everywhere, I've heard it's not a great snippet. CGFloat rgbComponents[4]; [color getRed:&rgbComponents[0] green:&rgbComponents[1] blue:&rgbComponents[2] alpha:&rgbComponents[3]]; CGFloat k = MIN(1-rgbComponents[0], MIN(1

Converting PDF without any images to CMYK

天涯浪子 提交于 2019-11-29 17:58:26
I read this post about how to convert PDF to CMYK, but when I try the accepted solution gs \ -o test-cmyk.pdf \ -sDEVICE=pdfwrite \ -sProcessColorModel=DeviceCMYK \ -sColorConversionStrategy=CMYK \ -sColorConversionStrategyForImages=CMYK \ test.pdf I does not get a pdf with CMYK color space, if my original pdf does not contain an image. If I add an image to it, I get the right result (checked with identify ). For example, if I create a svg with inskcape with one rectangle, export it to pdf, and then use the ghostscript command, it still gets a pdf in sRBG color space. But, if I add an image in

how can I convert an RGB image to CMYK and vice versa in Java?

依然范特西╮ 提交于 2019-11-29 14:13:51
our web app let users download dynamically generated images in different formats (bmp, png and jpeg). Some of our users download the images for printing, thus we would like to allow them to choose between RGB or CMYK. Is there a way to specify the color model when creating a RenderedImage/BufferedImage? If not, what is the default color model and how can I change it to another? Code snippets are welcome :) Thanks, Olivier. It appears that it's not simple and you'll have to either load up a color profile to do it or extend the colorspace to support CYMK. Some image formats doesn't allow CMYK
