Here is a simple demo project which draws an ITK RGBA image and show it in vtkRenderer. We will read DICOM data and put the ITK image above vtkImageData. CMakeLists.txt ULabelImage.h ULabelImage.cpp main.cpp
This article is a sequel to the previous one https://www.weiy.city/2023/04/draw-a-circle-around-mouse-postion-on-screen/. Let’s check if the vertex of cone is inside the red circle when we move mouse. CustomIteractorStyle.cpp UPaintBrush.cpp UPaintBrush.h Output:
The example draws a red circle around mouse position by vtkContextItem, vtkContext2D and vtkContextActor. When moving mouse, the red circle following it. CMakeLists.txt CustomIteractorStyle.h: CustomIteractorStyle.cpp UPaintBrush.h UPaintBrush.cpp main.cpp
This post is based on an old project Use ITK And VTK To Show DICOM Image. We want to add an above layer which drawed translucent red color on the gray image. Use alpha blend algorithm to merge two different color: origin color = $(R_1, G_1, B_1, 255)$ canvas color Read more…
Environment: VTK8.2.0, ITK5.0.0 Here is a demo project to display DICOM data by ITK and VTK. CMakeLists.txt main.cpp The folder contains a series of dcm files.Run it. Convert it to RGBA Image crudely.
When you use php to execute shell script to handle file, the filename may have to be preprocessing due to a few special characters. It’s better to set character encoding before running shell command.
In DOS/Windows text files a line break, also known as newline, is a combination of two characters: a Carriage Return (CR) followed by a Line Feed (LF). In Unix text files a line break is a single character: the Line Feed (LF).You can use cat -A fileName to check if there is ^M$ in Read more…
We had improved our online tool Images To MP4. You can upload the zip file which contains images with different sizes. The generated video’s size will be maxWidth x maxHeight of these images. It’s free and no registration requirement, enjoy it! Here is demo video generated from the tool Images Read more…
