Re: Problems with combining Set and Mogrify

Reporting back many years later. Issue still persists.

Is there anyone with ideas on a possible workaround?

Re: Unusual result while using GetPixel

I seemingly answered my own question today. Appears that you need to define the quantum depth when working on an image stream - the library apparently doesn't just "know" the quantum depth.

Oddly this is a non-issue when writing a file.

Unusual result while using GetPixel

Hi, I am right now using PerlMagick to iterate through the pixels of an image. I'm doing something super basic - just taking an image, iterating through the pixels and outputting the result as an HTML table. We've all seen this before... but I'm running into a problem. So basically if I parse the pi...

Re: Problems with combining Set and Mogrify

Reporting back a few months later and with a much newer version of ImageMagick - problem continues. I'm on "6.7.7.7_1" now, and the exact same issue reported above continues to occur on about 1 of every 300 images I process. The strip functionality definitely appears to have some sort of long standi...

Re: Problems with combining Set and Mogrify

Also as a clarification, I do not have any files at all here.

I accept these images as GLOBs via perl and then I store them in a DB. I never physically write them to a disk in the standard sense.

Re: Problems with combining Set and Mogrify

I disagree with your assessment. I do not have this problem with any images except for JPG. In addition I only have this problem with a small number of JPG, maybe 2% of the total 60K JPG that I have. If this were something that was supposed to happen, it would happen for all images. Also, please rea...

Re: Problems with combining Set and Mogrify

Yeah... so I wrote the code as I outlined above, and now it works properly. Either there is a bug, or some documentation needs to be written in order to explain what exactly is going on. Here is my code to accept and normalize an image: my $im = Image::Magick->new(); if ($im->BlobToImage($imagedata)...

Re: Problems with combining Set and Mogrify

Hi anthony, What you are performing in your suggestion is unfortunately not directly available via the API. If you do a search in this forum for stripping off the "create/modify" values using the perl API you will find a number of posts that contradict eachother. It's not even clear to me right now ...

Re: Problems with combing Set and Mogrify

Hi glennrp,

I am running "6.7.4.4_1" on FreeBSD, so this seemingly is an ongoing problem. I am willing to run all sorts of tests to ferret out the problem, I'm just not sure what else to do.

thanks.

Re: Problems with combining Set and Mogrify

Hi - thanks for the suggestion. I am aware of the Signature method, but for our use case it makes more sense to normalize the image metadata and generating a signature that way. I did not know of the Compare method, but we accept a large number of images per day, and comparing an uploaded image to 6...

Problems with combining Set and Mogrify

Hi, I'm attempting to detect duplicates among our internal image hosting service. Currently it has about 65K images, a fair number of which I suspect are duplicates. We have been using ImageMagick to open the images as uploaded from the user, validate them, and then store them into our database for ...
