Hi,
this seems a ZLib error, not a jpeg error. Is it possible to test this file?

Hi

You might want to use a web transfer service if it is too big for e-mail:

Hi,
are you using a beta of ImageEn? This bug should exist only in current beta release.
The workaround is to execute following line before load the image (just one time in your application):

iegUseCMYKProfile := false;

This will degrade CMYK->RGB conversion. Anyway you can still enable the embedded ICC color profile setting::

iegEnableCMS := true;

iegUseCMYKProfile and iegEnableCMS are defined in imageenio unit.

You can ask for the latest beta which fixes this problem at support email.

Hi,
it loses time applying the ICC profile (if you have set iegEnableCMS). Of course it is fast when iegEnableCMS=false.
Anyway here is my times:

#1 : apply file color profile
iegUseCMYKProfile := false;
iegEnableCMS := true;
2800 ms

#2 : do not apply color profile (raw CMYK->RGB conversion)
iegUseCMYKProfile := false;
iegEnableCMS := false;
890 ms

#3 (see below) : apply internal CMYK->sRGB profile
iegUseCMYKProfile := true
iegEnableCMS := false;
12823 ms <- not more with current beta

#4
Windows preview (windows 7)
about 3000 ms

However current beta (you can ask it at support email) optimizes the case #3, porting loading time of jpeg-CMYK without ICC to be equal to case #1.

It is still possible to load thumbnails instead of full images, if you want.
