Image resizing/changes wash out color

ppowell

using imagefttext($image, $ttf_size, 0, $image_txt_x, $image_txt_y, $ttf_color, "$ttfPath/$ttf", $image_text, array());

or imagecopyresampled() for resizing...

These commands do work as it does put text onto the image or resizing the image, however, the entire image is then completely washed out. All of the color is replaced with some gray-green tint (though the depths remain the same).

How can I use the imagefttext or imagecopyresampled() command and ensure my color schemes on the image remain intact unless I grayscale?

Thanx

I would use

ImageCopyResampled()
ImageCreateTrueColor()

if your resizing images always workout the ASPECT RATIO to rescale correctly, e.g.

formulae to calculate the aspect ratios:

wide images:

$imgwidth = (desired_height_of_newimg)
$thumbnail_height = (desired_height_of_newimg) * (height_of_source_image) /

(width_of_source_image)

tall images:

$imgwidth = (desired_height_of_newimg) * (width_of_source_image) / (height_of_source_image)
$imgheight = (desired_height_of_newimg)

hope it helps 🙂

Yep I found that out, imageCreateTrueColor is more reliable for color resizing. However, I have a problem.

How then can I ensure that while the image indeed changes, that I can SEE the changes when I return to that page with the changed image? Because, I don't, not even with header() tags, Meta Tags and forcing a random string into the URL. Verified by gonig into the file folder itself to realize that the image has indeed been changed, though.

not sure what you mean by that, do you mean the image on your browser stays the same? if so, perhaps it's a Cache problem, if so, you may want to stop caching of files by using a header(),

e.g.

header("Cache-Control: no-store, no-cache, must-revalidate");

could I view to code you are using?
