ImagXpress 13 for ActiveX - API Reference > Properties, Methods & Events by Category > Loading

Overview

ImagXpress® can load many file formats through many mechanisms. ImagXpress can load from a local or remote file, an ftp/http address, a memory buffer, or from user supplied data through a callback mechanism. ImagXpress can also crop, resize or rotate an image as it loads it. The following properties, methods and events affect the loading of images.

Properties

LoadCropX Gets and sets the left component (x-coordinate) of the top-left of the load crop rectangle.
LoadCropY Gets and sets the top component (y-coordinate) of the top-left of the load crop rectangle.
LoadMode Gets whether image data will be interpreted as a raw image format or a standard image format.
LoadResizeAntiAlias Gets and sets whether the image is anti-aliased during a load resize.
LoadResizeEnabled Gets and sets whether the image will be resized when loading an image.
LoadResizeHeight Gets and sets the height to resize the image to when loading an image.
LoadResizeMaintainAspectRatio Gets or sets the option to preserve image aspect ratio when loading an image into the viewer control.
LoadResizePreserveBlack Gets and sets whether when loading with LoadResizeEnabled, black objects in the image should be enhanced during the resize to increase readability.
LoadResizeWidth Gets and sets the width to resize the image to when loading an image.
