Let me know how to resolve these issues.

Thanks in advance .

"-flatten" removes transparency, so that's one problem solved. If you don't want to lose transparency, don't "-flatten".

"+matte" is deprecated. Don't use it. What do you want that to do?

If you are working with profiles, you almost certainly should not also use "-colorspace CMYK". Doing so will cause "colour shifting".

Any other problems?

you can download the source files from below link

2 Other Problems

1 . Colour shifting with RGB Conversion
2 . Loosing Alpha Channels

With v6.9.5-3, I can't see a colour problem with, for example: That image is opaque (according to IM's "identify"). But it does have a clip path, if you want to use that. See http://www.imagemagick.org/script/comma ... s.php#clip

pssvarma8881 wrote:2 . Loosing Alpha Channels

All of your commands use "-flatten". This removes all transparency. With no transparency, there is no need for an alpha channel.

When we are converting original PSD to PSD with 100 dpi we are losing alpha Channels . We need these alpha channels after the transformation as these will be used by our consumers.

For Color shifting please download the document which i uploaded to that .That document explains the differences between Source file and converted file.

Thanks for your quick response



For Alpha Channels :

I am i tried without -flatten command which solved my transparency problem .But i am still loosing the alpha channels.

Command i used :

convert -verbose -units PixelsPerInch +profile 8bim -density 100 %1[0] "M:%MYPARAM4%%~n1.PSD"

I do not know if this will help, but proper IM 6 and 7 syntax would read the input PSD image first before applying any settings or operators.

Your image has a group layer and adjustment layers. IM cannot deal with group or adjustment layer fully.

Also when I do

identify -verbose W_MYAG_CDH52_14143_001_ORIG.psd
Abort trap

But I will let one of the IM developers look at your file and explain further.

I also get on IM 6.9.5.10 Q16 Mac OSX
Abort trap


convert: memory allocation failed `tmp.psd' @ error/psd.c/WritePSDImage/3131.

thanks for your help .

Let me know the developer so that I can contact him.

P.S.S.Varma

He should contact you by tomorrow. I sent him a note to look at this topic.

You did not leave me a note but I got your e-mail. I will take a look at this topic later this week/weekend.

p.s. I really don't understand why IM fails with an 'Abort trap' on your system Fred. Can you give it a try with an earlier version?

dlemstra:

Not sure why you did not get my PM. But you got my email. The following current and older versions still abort trap on me.


IM 6.9.5.10
identify -verbose W_MYAG_CDH52_14143_001_ORIG.psd
Abort trap

im6959 identify -verbose W_MYAG_CDH52_14143_001_ORIG.psd
Abort trap

im6958 identify -verbose W_MYAG_CDH52_14143_001_ORIG.psd
Abort trap

IM 7.0.3.1
im7 magick identify -verbose W_MYAG_CDH52_14143_001_ORIG.psd
Abort trap
