Input 250 as width, 195 as height, choose 0.
Do RLE Convert.
Save image as BIN. Input again 250 and then 195 when it asks you for these values.

If you Cancel any of the questions then it won't save the image correctly.

Now I'm writting from my phone, but I'll have a second look. For testing the new version I went with 200x100, 200x198, 400x100.. maybe 250x195 is a "magic" combination that breaks things

Custom resolution for Logo:
As explained before, the CPU needs to have this image at the same resolution as the display, as it can't and doesn't have any engine for image resize.
If you want to be able to add to ConversHacker an image of a different resolution and have CH do the resize for you, then this might be possible, but it's easier to do this with another image editor.. something as easy to use as IrfanView.

Custom resolution for Icons and other Images that are used by Convers:
This is way beyond the scope of this tool. You'll have to edit the entire external flash memory in order to modify them and then to modify the main flash in order to let it know the new offsets.

DGAlexandru wrote: ↑31 Dec 2020, 14:37 OK, there is a BUG in CH regarding encoding of images that have a width size which isn't a multiple of 4.
I've replaced the archive for CH 1.3.3 in my previous post with a new one that has some improvements regarding the questions for the image width and height, but for now it still has this BUG, as I couldn't find an explanation on what goes wrong - most probably at RLE encoding.

### Improvement
- Now when you select another Theme the shown images are automatically repainted to show the change. It works for any image-related action: in VBF/BIN mode, in Convert Image mode, in RAW Image mode and so on.
### Fixed
- The BUG that was affecting Image Conversion is because of how QImage convertToFormat(QImage::Format_Indexed8) is designed:
it makes the new image's width (= bytes per line) to be a multiple of 4, so upon conversion it adds the "missing" bytes to every line (1, 2 or 3 bytes) and fills them with random data.
(https://forum.qt.io/topic/115559/qimage ... exed-image ; https://stackoverflow.com/questions/532 ... in-release)
The fix was done by skipping those added bytes in order not to encode them.

Using CH to downsize the image to the desired dimensions produces a pretty good quality (at least for tests) but I still recommend using an external image application that has more options regarding this.
400x198 resized to 249x195 CH.png 400x198 resized to 249x195 external.png
In this case the one resized with CH has more sharpness and it seems to actually be better
