Re: pixel and vectors

Hi snibgo,
thanks for your answer.
I know pdfimages to extract the raster images from a pdf, but is there a way to remove it from the pdf file?
This would make it a lot easier to handle the different parts separately.
Thanks
Roland

pixel and vectors

Hi imagick users, I use imageMagick to create large ( I mean really large) images to print out as wallpapers and other 20squaremeters+ posters. Therefore I always have to resize images by factor 10 or more, which works great on my 64GB Ram 16Core Xeon machine. But now I got a new customer providing ...

Re: extra large vector graphic

Aktually the printer I have is smaller but much faster... however, thanks for your answer. I thought it might be the wrong job for IM. But do I understand it right? If the vector is in SVG IM could o it? OR do you mean, if it is SVG, it is easy in general to slice it and then feed IM with the slices...

extra large vector graphic

Hi, it's me again, Roland. I successfully managed to deal with large images thanks to the help of anthony and fmw42 during the last few years. Thanks again. My main job is to enlarge images and cut them into slices to produce something similar to legths of wallpaper. The resulting images are up to 3...

Re: number of neighbors

Hi fmw42, nice to see that you are helping on every taskes :D Yes, the Mitchell is the standard an after testing some options I do agree that Mitchell is the best choice for me, too. So I just use the standard. When you say one output pixel uses 4 input pixel, is this one each on top, bottom, left a...

number of neighbors

Hi, this is a theoretical question wich affects my practical problem. I have to enlarge a given image to a huge size and then cut it into slices. It is simular to creating photo-wallpapers. The slices will be 200 inches long (from Top to bottom) and 20 inches wide, but up to 100 of them. You can ima...

Re: bug on very large images

negative I have 256GB of Ram, 128 as free Ram, 128 as a Ramdisk, where I store the image, I watch the mem in a seperate window and it is far away from swapping. Set MAGICK_TMPDIR to a filesystem with plenty of free disk space. What happens if I do not set it, Does it use the path I work in? Or is it...

I have to resize it to 76591x48633 still cmyk tiff (8.7 GB) with the command convert -resize 76591 img1.tif img2.tif (works fine with smaller resolution, lets say...

Re: split with overlap

@snibgo: That's exactly where I got it from :D So if there is no "normal" feature for cropping with overlap into fixed pixelsize, I wrap a pice of code around making sure the image gets enlarged just about that much that I can do the cropping into equally sized tiles with fixed pixels. I think I wil...

split with overlap

Hi forum, (hi anthony, hi fmw42), I want to split a larg image into rows. The standard would be (eg: 10.000 pixel into 10x 1000 pixel rows) convert large_image.tif -crop 1000x0 +repage +adjoin row_%03d.tif but I want to have an overlap. If I use convert large_image.tif -crop 10x1@ +repage +adjoin ro...

Resize speed

Hello forum, I just wondered if my imagemagick is slow or if just the task is too big. I have an Ubuntu 64bit running on a 8x4Core (yes, 32 Cores!) Xeon Server with 256GByte Ram. So this machine is top of the range I ever worked with. I am running : convert -version Version: ImageMagick 6.6.9-7 2012...

Re: cmyk - rgb - cmyk

Ok, it seems I got a workaround. I leave the original cmyk.tif file and create a new rgb.png with transparent background with the same dimensions. I do all my drawings and compostings and labelings there. then I convert this rgb.png to a cmyk-label.tif. and then i do a composite cmyk-label.tif cmyk....

Re: composite image with gravity

Hi, I just solved it myself, if you know a better way, tell me... <? $vimage = new Imagick(); $vimage->readImage($Filename); // I leave out all error protection, because it is void for this example $w=...; // it doesn't matter how I get these values... $h=...; $vimage->scaleImage($w, $h,TRUE); $x=.....

Re: composite image with gravity

Hi Fred, nice to meet you again, thanks for your never ending help! Hi Bonzo, thanks for your help, too! I obviously didn't make it clear, sorry. I have a large image, lets say 3000x4000 and I have an area in this image at position x/y with w/h which is settable by the user, lets say Position 2000x2...
