My code goes like this:

But this change the images appeareance, even after I have rendered to the image it a second time.
I have set the image to this:

So it should upsample somewhat softly giving the low-resolution pixel image a natural blur when sized up. However, The image gets much sharper if I resize it to its own size! What strange voodoo is this?

It depends on your virtual resolution

oldX = getImageWidth (renderImg)
oldY = getImageHeight (renderImg)
ResizeImage( renderImg, oldX, oldY)

Alpha Blending the pixels in the original image (alpha compositing), and not blending in the resize function (255 for all alpha).

Something you can play with when using the image/memblock commands...

CreateMemblockFromImage( memID, imageID )

CreateImageFromMemblock( imageID, memID )

Coding things my way since 1981 -- Currently using AppGameKit V2 Tier 1

Thanks, that was it exactly! I fixed it by adding a background-colored sprite behind the text when I rendered it to the image
