Commands to project an image to VS space are shown below.
| command | description | referer |
|---|---|---|
image-get-affine | Return affine_xy2vs (also affine_ij2vs and anchors_xy) estimated from anchors and anchors_ij in imageometry file. This command is subset of image-warp, without image manipulation. | |
image-warp-clicks | Offer similar functionality to image-warp. User can create imageometry file with clicking image and typing stage coordinates. This command cannot accept --range and --density options unlike image-warp. | |
image-warp | Project an image into VS space based on Affine matrix affine_xy2vs stored in imageometry file and export sub-area of the VS space as image file. | |
make_tiles | Project image to VS space and export squared sub-area of VS space as mosaic. The mosaic consists of tiles of image with 256x256 pixels. Note that the edges of the original image must be parallel to axis of VS space because this program does not support projection with rotation. Location to project the original image is set by x or y coordinate of four edges (x coordinate of left and right edges and y coordinate of upper and bottom edges). The squared sub-area on VS space is specified by center and width. The number of tiles depends on zoom levels. At zoom level 0 the squared sub-area is exported as a tile. Resolution of the tile is 256/width (pixel/micron). With increment of zoom level the number of exporting tiles is multiplied by 2x2. This program generates a series of tiles for zoom level from 0 to max. The zoom level max is specified by arguments. The tiles are compatible with Leaflet.js (a Javascript library for interactive maps). The tiles are exported as {zoom level}/{x}_{y}.png where x and y correspond to n-th coordinate of tile in horizontal and vertical direction. At zoom level 2, 16 tiles are exported as 2/0_0.png, 2/1_0.png, 2/2_0.png, ..., and 2/3_3.png with resolution 1024/width (pixel/micron). | rails project -- medusa |
Commands to estimate Affine matrix are shown below.
| command | description | referer |
|---|---|---|
h_from_points | Return Affine matrix calculated from four pairs of coordinates. Coordinates should be fed by arguments. | gem package -- opencvtool, gem package -- vstool, rake project -- mosaic-sem, gem package -- multi_stage |
haffine_from_points | Same as h_from_points but takes three pairs of coordinates instead of four. | |
affine_from_points | Same as haffine_from_points but coordinates should be fed by stdin instead of by arguments. | |
haffine_from_params | Return Affine matrix calculated from center of rotation in original image, rotation angle, and magnification. Parameters should be fed by arguments. | gem package -- opencvtool |
Commands to transform an image by Affine transform affine-ij2ij are shown below.
| command | description | referer |
|---|---|---|
warp_image | Transform an image using Affine matrix affine_ij2ij and export image. Affine matrix can be specified by (1) 3x3 matrix, (2) center of rotation in original image, rotation angle, and magnification as similar to haffine_from_params, and (3) coordinates where the 4 corners of the original image are projected. The area to be exported can be specified by width and height via arguments. Without width and height specified, those of the original image would be applied. This program also imposes the original image on wall image. In this case, the area to be exported is set by width and height of the wall image. | gem package -- opencvtool, gem package -- vstool, rake project -- mosaic-sem, gem package -- multi_stage |
image_in_image | Impose an image on wall image after Affine transformation. Affine matrix affine_ij2ij is specified by coordinates where the 4 corners of the original image are projected. This command is subset of warp_image. | rails project -- medusa |
transform_image (obsolete) | This command is subset of warp_image. The area to be exported is set by width and height of the original image. | |
transform_points | Return coordinates after Affine transformation. Original coordinates and Affine matrix are specified by arguments. | gem package -- opencvtool, gem package -- vstool, rake project -- mosaic-sem, gem package -- multi_stage |
Commands to mix images and extract image are shown below.
| command | description | referer |
|---|---|---|
blend-image | Impose image to wall image with alpha blend techniques. Location to impose the image is set by ij coordinates via arguments. | |
crop_image | Crop a rectangular region of an image. | gem package -- opencvtool, gem package -- vstool, rake project -- mosaic-sem, gem package -- multi_stage |
