Version of IM: ImageMagick 6.4.2 11/20/12 Q16 OpenMP

So I have the following php code to attach a some IPTC headers into my image using 8BIMTEXT, but I can't for the life of me get it working

<?php

$imWand2 = NewMagickWand();

MagickReadImage( $imWand2, "testinput.jpg" );

$meta = "2#40 ...

not quite solved yet :(

so the last image in the command ends up with 16 sizes

/images/3/0/44/966/472/msyri_phototour22_J.jpg
/images/3/0/44/966/472/msyri_phototour22_J-0.jpg
/images/3/0/44/966/472/msyri_phototour22_J-1.jpg
/images/3/0/44/966/472/msyri_phototour22_J-2.jpg
/images/3/0/44/966/472 ...

sorry it is there, I just was reformatting it so it was readable! (ive added it in now!)

thanks I dumbly copied that part about loseless.

awesome! that makes perfect sense.

now another issue, the last image i try to create never gets created:


convert 44966473.jpg -colorspace RGB -write mpr:image +delete
( mpr:image -filter Lanczos -resize 670x480! -format JPEG -compress Lossless -quality 85.0 -colorspace RGB -write /images/3/0/44 ...

well that was dumb of me.

i moved to using mpr:image method

convert input.jpg -write mpr:image +delete
( mpr:image -thumbnail x480 -write 480_wide.jpg )
( mpr:image -thumbnail x250 -write 250_wide.jpg )
( mpr:image -thumbnail x100 -write 100_wide.jpg )
( mpr:image -thumbnail 64x64! -write 64 ...

the major problem I have is the results are completely unexpected and differ, mainly because the order of the commands is different per invocation also.

I'll see if i can do it the way you proposed with im4java

yes, I want use the first "original" image and create multiple sizes different sizes from it, unless im wrong (which wouldnt surprise me) I believe this is the way to do it as

+clone, should clone the image from the stack (the original image) then -write will put my new image on the stack, then ...

So I am using IM4JAVA to create a commandline call and it outputs the following, now problem is even though I tell imagemagick to force the size (-resize WxH!) it still does not do exactly what it is told, highly confusing.

I have moved each sub operation onto a new line for readability.

Hi,

I've been running around in circles trying to workout where ImageMagick gets the colorspace of a JPEG from, I know there must be somewhere in the metadata, but I can't for the life of me find it and traversing the IM source is not as easy as I thought it would be :(

any help would be great

I ...

mmmm yeh

just for reference it kicks out that error in MagickReadImage()
