# TIP 545: image photo SVG options: remove -unit and add target height/width option
	Author:         Harald Oehlmann <[email protected]>
	State:          Draft
	Type:           Project
	Vote:           In progress
	Created:        19-May-2019
	Keywords:       Tk, image
	Tcl-Version:    8.7
	Tk-Branch:     tip-545-svg-options




-----

# Abstract

Image photo SVG support was added to Tk by TIP 507.
This TIP is about the options of SVG rendering:

................................................................................

Rene has another use-case for visual graph generation.
A svg file is created on the fly using the given data.
This is then rendered and displayed by a label widget.
This procedure is faster than the canvas or the tkpath widget (and has much less features).
This solution is a good fit to this application.

# Abstract

Image photo SVG support was added to Tk by TIP 507.
This TIP is about the options of SVG rendering:

................................................................................

Rene has another use-case for visual graph generation.
A svg file is created on the fly using the given data.
This is then rendered and displayed by a label widget.
This procedure is faster than the canvas or the tkpath widget (and has much less features).
This solution is a good fit to this application.

Francois Vogel commented with his vote:

The TIP says "The image size is set to height 1 and/or width 1 if width and/or height is 0 after scaling and rounding.". Where is that statement implemented?

IMO this story is a leftover in the TIP from a previous mistake made in the implementation that I corrected later (details at https://sourceforge.net/p/tcl/mailman/message/36693070/ ). If so, I would prefer the TIP to be corrected so that it accurately reflects the implementation: all this story should be deleted throughout the TIP.
