Icon in the upper right of the AJAX viewer, which will bring up the menu shown in the figure below. Currently, you can obtain all of these variable values from BrainMaps images of interest by clicking on the Width of the image in pixels, though the Brain Maps API will try to obtain these values automatically if they are absent. It is also recommended that you specify the The 'path' refers to the absolute or relative image path. There is one javascript variable that must be specified, either through the URL or through the HTML source code: the image You will see Brain Maps is now on your site, and it should look like the page at the following URL: If you upload these files to your web server, then try loading the following page: #IMAGEVIEWER FREE#The Brain Maps API is a free service, available for any web site that is free to consumers.Ĭlick on the thumbnail below to see an example of the Brain Maps API in action, and when you do, try using your mouse scroll wheel to zoom in and out.ĭownload the following files (by right-click and save): It has been designed to be small and fast, and to consume very little memory, yet still be very functional and extensible. The Brain Maps API is a lightweight multiresolution image viewer with customizable label overlays that lets you embed BrainMaps images in your own web pages with JavaScript, and that can also be used with your own multiresolution images. Saunders Monodelphis domestica Atlas Legend (xls).Complete Delineated Saunders Monodelphis domestica Atlas (pdf).Simple flat shading and transparency rendering is also supported to help visualize certain datasets. 3D TexturesģD textures can be displayed as well and are supported by the majority of image viewer features (export, custom filtering, mipmap generation and more). The detailed filter guide can be found here. #param Factor, factor, float, 1.0, 0 // this function will be called once for each pixel float4 filter( int2 pixelCoord, int2 size)Ĭolor.rgb = pow( abs(color.rgb * factor), float3(invGamma, invGamma, invGamma)) define displayed name, variable name (for the shader), variable type, default value and optional minmum, maximum #setting description, Nonlinear operation used to encode and decode luminance. Some filter, like the gaussian blur, are already implemented and can be imported via the filter tab:Īn example for a simple gamma correction filter would look like this: User defined parameters can be set from within the GUI. Only a single function needs to be implemented that will be called for each pixel of the image. Custom HLSL Compute Shader Filterįilter are HLSL compute shader that can be imported by the ImageViewer. The detailed image equation guide can be found here. sRGB values are in range and you can combine them with following operators: * + - / ^. I0 and I1 are the pixels from the first and the second image. Additionally you can use the + and - Key to adjust the exposure. Side By Side Comparision and Image ManipulationĬompare up to 4 images side by side and use custom formulas to modify the displayed result. You can create a Cubemap or an arbitrary Texture2DArray from multiple images with File->Import as Array. View the raw polar image or look around in polar mode:Ĭonvert between Lat-Long and Cubemaps with Tools->LatLong to Cubemap and Tools->Cubemap to LatLong. Select a specific mipmap level and layer (face) of DDS and KTX textures and view cubemaps in projection or crossview: The display type can be changed from linear color space to Srgb color space via: View->Pixel Display->Format. The status bar displays the current texture coordinates (cursor) along with the corresponding RGBA color values in linear color space. computations are done in linear color space.mipmap generation (including box filter and lanczos).arithmetic image manipulation (image calculator).If you want to build and debug the Image Viewer, follow the instructions here. Microsoft Visual C++ Redistributable for Visual Studio 2019.block compression (BC1-BC7) for DDS, KTX.An image viewer for anyone related to computer graphics.
