I found some error in my log like:

ImageMagick only creates massive temporary files if the input file has a sizable width or height or if there are hundreds / thousands of frames in the image. As discussed on the web page we referenced, our web interface to ImageMagick pings an image first to ensure it has reasonable dimensions ...

Hi Magick:
thanks for recommendation.maybe I should describe more for my server.After read some material from forum,I have compiled and installed the IM with "-with-quantum-depth=8"option,after a night of running,from monitor I can still see ...

well,I use ImageMagick in my server program,this server will process image from network continuously.When I update the IM from 6.7.6 to 6.8.0-4,I found that there must be several times in one day that It will create some very large temporary files in /tmp,usually thousands of MB.when It write such a ...

I have similar problem.ImageMagick will create very large files in /tmp,thousands of MB.If I reinstall it with "--with-quantum-depth=8"option,it can help?

Webp conversion works for us with 6.8.0-4 under Fedora Linux. We could not try your image file, your link is not working properly.
I have uploaded the output file again and got a url "http://url.cn/4lqMTk",copy it to a chrome or ie,navigate to the responding page and click the download or in ...

can u see the input png I posted above? May I have someway(e.g. email?) to send u the input png and the output webp I got?I use 6.8.0-4 and webp2.0 it works well for ...

We can reproduce the problem you posted and have a patch in ImageMagick 6.8.0-3 Beta available by sometime tomorrow. Thanks.
well,I have tested it with ImageMagick-6.8.0-4.tar.gz,the quality param can affect the output webp file size,but the output webp picture is still wrong.the input basketball ...

magick wrote:The ICO format does not have a magic string to help identify it like JPEG or PNG does. Instead you must hint to ImageMagick the format the blob is in. Use magick("ICO") before you read the blob.

thank you so much.With your help,I have solved it successfully!

I noticed that the difference between these two way lie in that Image constructor will call the 'void Magick::Image::read ( const std::string &imageSpec_ )'in Image.cpp while the other will call the 'void Magick::Image::read ( const Blob &blob_ )',is this the reason?some pic format can only read ...

I use the ImageMagick-6.7.9-10 installed from source code on linux,and then write a very simple code to test IM API for for format conversion.like following:

Image image(argv[1]);
image.magick( argv[2] ); // Set JPEG output format
cout<<"File Name after magick:"<<image.fileName()<<endl;
image ...

I don't know much about webp format, but if it is a pixel format and not vector, then the -quality should come after reading the input image. But I am not sure that -quality is relevant to webp format -- that is I don't know if IM understands what quality means for that format. I believe that ...

I use the ImageMagick-6.7.9-10 and libwebp-0.2.0 both from source code an suse-like linux system and found two problem:

1.when convert a jpeg file to webp, the output file can be viewed,but file size is not affected by quality param.
Cammand line like: convert -quality 80 a.jpg a.webp

2.when ...

well,I want to use the IM to convert a jpg picture to webp format with different quality param to test how many bytes I can saved.code like this:

taf::Int32 convert(const struct SInfo targetInfo,
vector<char> &targetData)
{

try{
if(m_image.magick()== "JPEG")
{

if (targetInfo.type=="WEBP ...
