<p>You must upload one .png or .bmp image and one .grit file for each image you want converted. Uploading multiple pairs of images and GRIT files at a time is supported.</p>
|
|
<p>A ZIP file with your converted GRF files inside will then be downloaded.</p>
|
|
<p>
|
|
If you graphics come out corrupted it's probably because the palettes are somehow wrong.
|
|
Check that there aren't more colors in the image than the <code>-pn</code> in your GRIT file. (ex. <code>-pn32</code> is 32 colors)
|
|
It may work better to upload a non-paletted image depending on the image.
