Hi,

I've been blocked on this for a whole day. Really need some help or idea.

I run the command:

convert -limit area 128mb -limit map 256mb -limit disk 512mb -format %w,%h, <inputFile> -identify <outputFile>

It give the error: Could not read file as specified mime-type, file is invalid or corrupted: Illegal Argument Exception, bailing out: Could not read file as type 'image/gif' or 'image/jpeg', Not a JPEG file: starts with 0xff 0xd9

However, when I remove the three -limit argument and run only

convert -format %w,%h, <inputFile> -identify <outputFile>

It convert successfully.

Why is this?

I've also tried change the limit to smaller or bigger value and even tried change mb to MB or MiB(though I don't think that is the problem) but no luck.

Please hlep! Thanks!

try

identify -ping -format "%w,%h" yourimage

or

convert yourimage -ping -format "%w,%h" info:

or

convert -limit memory 32 -limit map 32 yourimage -ping -format "%w,%h" info:

if you use a disk limit, it will give an error message if you exceed the limit

try leaving off the mb

Thank you. But it doesn't solve my problem

If I'm not specifying a disk limit will there be any problem?

When it gives the error, is that because the disk limit (512mb) is too small? But I think it wouldn't take much space to process image, right? What is a proper value for disk size, e.g. 2 times max acceptable size? What about other limit value?

Any insight?

convert -limit area 128mb ...

"MB" is case-sensitive and should be in capitals. I suspect that "mb" is ignored, so it tries to fit the image in 128 bytes.

(This is on v6.8.7-0 on Windows 7.)

I tried. But that doesn't seem make any difference...

Try

• convert -limit area 128MB -list resource

It should return an area limit of 128MB. If so, ImageMagick is behaving as expected.

It gives:
convert: invalid argument for option '128MB' : -limit

What version are you running? On what platform?

These together provides some information which moves me to the next question:

when I run:
convert -limit map area 128 -limit map 256 -limit disk 512 -list resource

it gives:
File Area Memory Map Disk
-----------------------------------------------------------------------------
2.6e+02mb 1.3e+02mb 5.1e+02gb

It seems IM has default unit for different resource(Area in mb, Map in mb and Disk in gb)? Any way to make disk limit down to 512mb?

Tried on 6.5.6 and 6.8.2 on RedHat
