## Member Enumeration Documentation

enum MyGUI::Canvas::TextureResizeMode

Available resize and view modes of texture

Remarks
  PT - Power of Two (size)

Enumerator
TRM_PT_CONST_SIZE | Mode when the texture has constant size and stretching on all widget. Remarks The size specified at creation of the texture increases to nearest power of two and doesn't change any more. Texture is always stretched on all widget.
TRM_PT_VIEW_REQUESTED | Mode when texture pixels look as is. Remarks The texture size is always more or equal than the widget size and is equal to a power of two. Note The size specified at creation of the texture is ignored. The texture is automatically recreated if the size of the widget becomes bigger.
TRM_PT_VIEW_ALL | Mode when the texture stretched on all widget and automatically changes the size for nice look. Remarks The mode same as TRM_PT_VIEW_REQUESTED, but the texture is scaled till the size of the widget. Note The size specified at creation of the texture is ignored. The texture is automatically recreated if the size of the widget becomes bigger.
