Thanks for confirming this

What script? I meant the way the command line works, you can give multiple commands in a single line and I read some posts here telling that way imagemagick provide some performance improvements. I was trying to improve performance of my application which uses imagemagick ( imagemagick is eating CPU ...

Hi all,

Is it possible to resize same image multiple times for different sizes in single api, same way script is doing?

Thanks in advance

Hi Rodlie,
Thanks for your reply. I just used the api as you suggested.
Is the per pixel will take 4 bits here? Is the one bit for alpha ?

Hi,

Is some one aware about Magick++ API for creating 8 bitmap (1 byte per pixel).
I am using Imagemagick version 7

Thanks in advance

Thanks for your reply. It will test the performance of draw as well. As you said, with annotate we can draw text with single API call. I just want to know whats the in Magick++ api to create 8 bit bmp image. I didnt see any api for that?? I am sorry that I am asking too many queries in a single ...

Thanks for the comment! I am going keep the sample algorithm as as now for scaling.
Is there any difference between annotation and label in terms of performs? Or which is better API for text rendering?

Any thoughts???

Interesting! As you said, I have already done the below steps ( disabled HDRI, Q length is 8 bit) except disabling OpenMP. Those steps improved performance a lot. I am not doing complex steps, doing text to bmp image conversion basically. But this is very frequent mostly less than a second. Is there ...

Right now we don't have an option for GPU :(. This is an embedded device we have the limitation over hardware resources. Only thing I am trying to achieve is optimize as much as possible. Since you guys are expert in imagemagick, please suggest some of the performance improvement tricks from ...

Thanks dlemstra by confirming API :) But now I am wondering about the performance. I wanted to scale the image every second or even less. I have tried using "resize" API and then used "scale" API which is even better. And then I have used sample API which makes the cpu usage even better. This will ...

Hi,

I am not sure this will help you or not. I have faced same kind of issue, you probably need to set environment variable "MAGICK_CONFIGURE_PATH".

Hi, Thanks for your reply, I didnt see any API called SetImageOption in Magick++. I have seen another api callled "defineValue" where I can give magick option as "bmp" and key as "subtype" and value as "ARGB1555". Is it the right API? How can I get bmp pixels from Image object created???

Hi,

Thanks for your quick response.
I am using ImageMagick 7.0.7-31 and I am looking for the APIs, since I am using ImageMagick++.

Hi, I am new to imagemagick and started using ImageMagic++ api for the image operations. So far its a great product, but I need help from you guys. I need to create a bmp image with ARGB1555 (16 bit), since I need to pass pixels as ARGB1555 to hardware(and its support only this format). I could not ...
