Feature Request: replace Bound(src.Bounds) by Bound(src)

[celogeek]

Hi,

I want to create a CropMargin filter. This filter will look in the img, and remove the white line all around the image.
For this I need the source image to look for the pixel I want to remove.

If the Bounds method receive the src instead the src.Bounds, that would make a lot for filter possible.

For now I have to calculate the bound before I can create the filter Crop and apply it.

May be I can return the srcBound, and in the Draw I can draw the return the src.sub image. That may work, but the g.Bounds will return the wrong value.

Do you think it could be a possible evolution?

Indeed, it's what I do.
I first lookup for margin, then use the crop filter.

In the end, I can't use the gift instance for several images,
I create one set of filters, and transform 1 image,
then create another set of filters for another image.

Ideally we create a series of changes we want to do, then apply to a list of images.

Like:

• Cut margin
• Rotate if needed
• Change britness
• Change contrast
• Resize to fit / fill a specific bound
• Apply gray scale

So sometimes conditional filter, will endup doing nothing.
In that case, I still need to copy src to dst. I don't have a noop operation that can skip some filter based on condition.

but well, with parallel processing, and disabling parallelisation, I can handle a lot of transformation, in a pretty short amount of times.
I may try to optimise this, but that's pretty good already.
