Size – Size to which the input image is to be resized. If the image is neither a PIL image nor a tensor image, then we first convert it to a tensor image and then apply the Resize()transform. This transform also accepts a batch of tensor images, which is a tensor with where B is the number of images in the batch. A tensor image is a torch tensor with shape, where C is the number of channels, H is the image height, and W is the image width. Resize() accepts both PIL and tensor images. It's one of the transforms provided by the ansforms module. Įxample 2: When in a GET_IMAGE request using dpi.The Resize() transform resizes the input image to a given size. When parent element is GET_LAYOUT when using ArcMap Server:īack to top Examples for IMAGESIZE Example 1: When in a GET_IMAGE request using printwidth and printheight. When parent element is GET_IMAGE when using Image Server:ĭetermines whether to increase or decrease symbology in relative proportion to a map image as the image increases or decreases in size. When parent element is GET_IMAGE when using ArcMap Server: The actual size is returned as the height and width in OUTPUT.
This applies only to the following formats: GIF, JPG, BMP, PNG24, and PNG8. When using GET_LAYOUT with ArcMap Image Services, height and width are resized automatically to keep the proper page ratio for the layout.A more thorough explanation of using these attributes is in the IMAGESIZE section of Using GET_IMAGE and IMAGE with Image Services or Using GET_IMAGE and IMAGE with ArcMap Image Services. In the third option, calculations are made using dots per inch (dpi). In the second option, calculations are made using pixels. Both options produce the same results, but the method for calculating the new map differs. To avoid changing the scale as a map is increased or decreased in size, the second two options do take scale dependencies into consideration. The result is that data content and layer rendering may change as the width and height increase or decrease. If the size of the image changes, but the envelope remains the same, the scale of the map changes. (Image and ArcMap Image Services)The first method is the default, but this method does not take scale dependencies into consideration. By using printwidth and printheight along with height and width.The image output map size can be determined three different ways:.If a layer is out of range based on the scale, it will not be extracted. In a GET_EXTRACT request, IMAGESIZE is used to calculate which layers should be extracted based on any scale dependencies.Used only with Image, Extract, and ArcMap Servers.When the output type is AI, EMF, EPS, PDF, or SVG, dpi takes precedence over height and width, and the height and width are ignored. If height and width are not specified, the image size is calculated based on a dpi of 96. The image size is based on the values of height and width. When using GET_LAYOUT with ArcMap Image Services, the attribute dpi is ignored when using the following formats: GIF, JPG, BMP, PNG24, and PNG8.When used with GET_EXTRACT, defines which layers should be extracted if scale dependencies are present. (r): Attribute or child element is required.ĭescriptionWhen used with GET_IMAGE or GET_LAYOUT, defines width and height of output map.
