Category: GUI - AXIS Group: None Status: Open Resolution: None Priority: 1 Private: No Submitted By: Bill Richman (brichman) Assigned to: Chris Radek (cradek) Summary: png file with gradient fade not converting correctly Initial Comment: I have a png file produced via export from InkScape, which includes some fairly fine detail with a gradient fade applied from top to bottom, which I'm hoping will cause the image to be engraved shallowly at the bottom and more deeply at the top. If I look at it with an image viewer, it looks fine, but when I try to import it to Axis, it comes up with most of the details replaced by solid black. If I let it go ahead and generate g-code, it does seem to have lost all the detail. If I hide the gradient fade in InkScape, however, and import that image with Axis, it renders the detail into g-code just fine (except without the slope I'm after). Any suggestions? ---------------------------------------------------------------------- >Comment By: Jeff Epler (jepler) Date: 2010-06-09 08:22 Message: Your images have an alpha channel. Image2gcode was not designed for images with an alpha channel. It looks like it treats a pixel that is not 100% transparent as if it is fully black(?) but images that are 100% transparent as white. I opened the gradient image in gimp and with the background color set to white invoked Image > Flatter Image, which gives an image with opaque pixels blended against a white background. This gives me an image that looks OK in the image2gcode preview. ---------------------------------------------------------------------- Comment By: Bill Richman (brichman) Date: 2010-06-08 21:47 Message: Hmm - it may be transparency in the image causing my problem. Let me work on it a bit before you spend any time on this. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=106744&aid=3013502&group_id=6744 ------------------------------------------------------------------------------ ThinkGeek and WIRED's GeekDad team up for the Ultimate GeekDad Father's Day Giveaway.
