Loads a new GdkPixbuf from filename and returns it. The caller must assume the reference to the reurned pixbuf. If an error occurred, error is set and NULL is returned.

pixbufFromFileAtMaxSize

pixbufFromFileAtMaxSize Source #

Arguments

:: (HasCallStack, MonadIO m)
=> Text	`filename`: A file name
-> Int32	`maxWidth`: The requested max width
-> Int32	`maxHeight`: The requested max height
-> m (Maybe Pixbuf)	Returns: A pixbuf, or `Nothing` on error. (Can throw `GError`)

Deprecated: Use handleNewFromFile and handleRenderDocument instead.

Loads a new GdkPixbuf from filename and returns it. This pixbuf is uniformly scaled so that the it fits into a rectangle of size max_width * max_height. The caller must assume the reference to the returned pixbuf. If an error occurred, error is set and NULL is returned.

pixbufFromFileAtSize

pixbufFromFileAtSize Source #

Arguments

:: (HasCallStack, MonadIO m)
=> Text	`filename`: A file name
-> Int32	`width`: The new width, or -1
-> Int32	`height`: The new height, or -1
-> m (Maybe Pixbuf)	Returns: A pixbuf, or `Nothing` on error. (Can throw `GError`)

Deprecated: Use handleNewFromFile and handleRenderDocument instead.

Loads a new GdkPixbuf from filename and returns it. This pixbuf is scaled from the size indicated to the new size indicated by width and height. If both of these are -1, then the default size of the image being loaded is used. The caller must assume the reference to the returned pixbuf. If an error occurred, error is set and NULL is returned.

pixbufFromFileAtZoom

pixbufFromFileAtZoom Source #

Arguments

:: (HasCallStack, MonadIO m)
=> Text	`filename`: A file name
-> Double	`xZoom`: The horizontal zoom factor
-> Double	`yZoom`: The vertical zoom factor
-> m (Maybe Pixbuf)	Returns: A pixbuf, or `Nothing` on error. (Can throw `GError`)

Deprecated: Use handleNewFromFile and handleRenderDocument instead.

Loads a new GdkPixbuf from filename and returns it. This pixbuf is scaled from the size indicated by the file by a factor of xZoom and yZoom. The caller must assume the reference to the returned pixbuf. If an error occurred, error is set and NULL is returned.

pixbufFromFileAtZoomWithMax

pixbufFromFileAtZoomWithMax Source #

Arguments

:: (HasCallStack, MonadIO m)
=> Text	`filename`: A file name
-> Double	`xZoom`: The horizontal zoom factor
-> Double	`yZoom`: The vertical zoom factor
-> Int32	`maxWidth`: The requested max width
-> Int32	`maxHeight`: The requested max height
-> m (Maybe Pixbuf)	Returns: A pixbuf, or `Nothing` on error. (Can throw `GError`)

Deprecated: Use handleNewFromFile and handleRenderDocument instead.

Loads a new GdkPixbuf from filename and returns it. This pixbuf is scaled from the size indicated by the file by a factor of xZoom and yZoom. If the resulting pixbuf would be larger than max_width/max_heigh it is uniformly scaled down to fit in that rectangle. The caller must assume the reference to the returned pixbuf. If an error occurred, error is set and NULL is returned.

setDefaultDpi

setDefaultDpi Source #

Arguments

:: (HasCallStack, MonadIO m)
=> Double	`dpi`: Dots Per Inch (aka Pixels Per Inch)
-> m ()

Deprecated: (Since version 2.42.3)This function used to set a global default DPI. However,it only worked if it was called before any Handle objects had beencreated; it would not work after that. To avoid global mutable state, pleaseuse handleSetDpi instead.

Do not use this function. Create an Handle and call handleSetDpi on it instead.

Since: 2.8

setDefaultDpiXY

setDefaultDpiXY Source #

Arguments

:: (HasCallStack, MonadIO m)
=> Double	`dpiX`: Dots Per Inch (aka Pixels Per Inch)
-> Double	`dpiY`: Dots Per Inch (aka Pixels Per Inch)
-> m ()

Deprecated: (Since version 2.42.3)This function used to set a global default DPI. However,it only worked if it was called before any Handle objects had beencreated; it would not work after that. To avoid global mutable state, pleaseuse handleSetDpi instead.

Do not use this function. Create an Handle and call handleSetDpiXY on it instead.

Deprecated: (Since version 2.36)There is no need to de-initialize librsvg.

This function does nothing.
