An instance of the ImageCollection class contains all images in a Text Control document or part of the document represented through objects of the type Image. An instance of this class can be obtained with the TextControl.Images, HeaderFooter.Images or TextFrame.Images property. The ImageCollection class implements the IEnumerable and the ICollection interfaces.

The following example iterates all images and sets the Image.SaveMode to SaveAsFileReference, so that all images will be exported the next time the document is saved. The images, will be saved in a subfolder called "'document name'_Images" of the location where the document has been saved to. The additional properties can be used to set the image's quality, format and maximum resolution.

foreach (TXTextControl.Image myImage in textControl1.Images) 
myImage.SaveMode = TXTextControl.ImageSaveMode.SaveAsFileReference;
myImage.ExportCompressionQuality = 100; //Export with maximum quality 
myImage.ExportFilterIndex = 4; //Export as PNG format
myImage.ExportMaxResolution = 96; //Export with 96 DPI max 
For Each MyImage As TXTextControl.Image In TextControl1.Images

MyImage.SaveMode = TXTextControl.ImageSaveMode.SaveAsFileReference
MyImage.ExportCompressionQuality = 100 'Export with maximum quality 
MyImage.ExportFilterIndex = 3 'Export as PNG
MyImage.ExportMaxResolution = 96 'Export with 96 DPI max
