Re: How to reduce png file size

Hi glennrp,

yes, that did it! Puh... I'm glad. Now my images are only about 1/3 of the original size. This is much more 'realistic'.

I do not really understand what happens. Anyway, many thanks for your solution!!! :D

Re: How to reduce png file size

Thank you for your help. I think 8-bit is not appropriate since in.png is a photo. Also the round border should be smooth. At least it shouldn't be gif-quality. (Sorry, I don't know the terms, but is it the alpha channel that is required?) What is interesting: I have opened the created out.pnp in ...

How to reduce png file size

Hi, I have a convert command that produces a png file which is too big for my purposes. I get files with more than 200 kb but it should be less than 50 kb, if this is possible. How do I have to modify the parameters? What can I do? The quality of the image should be as close as possible to the ...

:D Now it's working! :D I was told that there is a newer version in /usr/bin/im_6.6. With this version it works. Thank you both for your help.

Re: Create a round section of a picture

Okay, I have realized now that this version is already 5 years old. I guess, some things won't work with this version. I hope I can get a newer version installed. But I'm wondering if my request isn't possible with this version or if there are any other approaches.

Re: Create a round section of a picture

Dear Bonzo and fmw42, thanks for your help so far. @Bonzo: This would be a possible solution. However, I cannot try this out. My solution worked locally on Windows fine but on the Linux server I've got a problem with '-alpha Set'. This creates an error as it seems. Version on the server is 6.2.4 Q16 ...

Re: Create a round section of a picture

The processing will be started with PHP, but with a direct command line call not with Imagick-API.

IM itselsf is not able to do some calculations for this? Though, it is no problem to this with PHP.
